Set micro-grid launch WeChat IC: "Everyday IC", big news immediately released, every day IC, every day set micro-network, micro-into a! Scan the end of the two-dimensional code to add attention.
1. Dunlop will continue to be responsible for the letter Wei, nearly 40 cases related to the ongoing proceedings;
Set micro-mesh news:
In the semiconductor and the entire science and technology, there is a common phenomenon, once the company employees move their own old house 'cheese' often tend to defeat the end, caught in shame is also often occur in the industry is the most familiar case of Lee than male And Huawei's story.However, today to say is that in the field of fingerprint chip, a listed company after the departure of R & D vice president, not only take R & D personnel to their own homes, but also in violation of the non-competition restrictions to engage in the same business with the old club.
Insiders may have thought that this is Dunlop Technology and Xin Wei, general manager of Mo Weihua (also the original vice president of Thai Science and Technology R & D) between the incidents, according to industry sources, Xin Wei not only engaged in the same business and Duntech Fingerprinting business, but also in terms of investment and financing 'downwind' is about to usher in the second million financing.
So, Xin Wei can go to this step is Dunta Technology does not chase it? Or that the chase has been completed? Duntai Chairman Hu Zhengtao Science and Technology recently accepted a micro-network interview, the whole story of the ins and outs of the incident , And stressed that DunTech Technology will retain all the responsibility for the responsibility. At present, there are still about 40 related lawsuits concerning the infringement related to Moeller and Xinwei.
Leave Dunlop independent, rely on labor relations to avoid competition restrictions
Pull back the time to March 2015, it is time for Moelva to completely leave Dunlop Technology.
Prior to this, Mo Lianghua joined Dun Tai in September 2006. After nine years of tempering and promotion, Mo Lianghua has grown from an initial R & D engineer to a vice president of R & D at Dun Tai, after the founder of Dun Tai Hu Zhengzheng's number two; and after leaving in March 2015, just over three months, Mo Lianghua officially established Shenzhen Xin Wei Technology Co., Ltd. (hereinafter referred to as 'Xin Wei') and served as general manager, start And Dun Tai, the same cut into the field of fingerprint chips.
As for leaving Dunlop, MoLianghua claimed that he had "left Dunlop and wanted to make a small test-chop in the capital market," and later set up XinWei Technologies, which claimed to be "I'm in full swing in the capital market, , By a friend's invitation to join Xin Wei.
However, Dun Tai pointed out that this is not a fact.
Dun Tai said Mo Liang Hua made a lot of groundwork before leaving the company. Prior to his departure, he had set up Shenzhen Millstone Technology Co., Ltd. ("Millstone") for fingerprint recognition technology research and development, with him at the same time there are more than a dozen BitTun Technology R & D engineers leave, some leave Dun Tai to join the letter Wei, some to avoid competing restrictions and its personnel relations linked to the seemingly unrelated to the business of Dun Tai related affiliates. At that time Dun and fingerprint chip R & D team From nearly 50 people to concentrate after leaving only a few people, Dun Tai fingerprint chip research and development team collapsed overnight.
The author found through the eyes of the day, letter Wei was established in June 25, 2015, Mo Lianghua as a director of the company, the direct shareholding of 20%; February 26, 2015 set up grinding stone company, direct shareholding 99.9% of the total shares of the Company; Shenzhen Core Technology (Limited Partnership) ("Core Wei") was established on 24 April 2015 with a holding of 98%; and on May 8, 2015, Shenzhen United Technologies Co., Ltd. (limited partnership) Referred to as 'stone'), holding 65%; November 20, 2015 letter Wei biological established .Mo Lianghua directly or through the millstone, stone, Wei indirectly hold 80% equity interest in Wei, through layers Ownership structure design, openly engaged in fingerprint identification business by the letter Wei.
As we all know, as a technology company, especially the chip company's technology research and development staff to sign a non-compete agreement that requires a period of time to leave the original owner can not engage in the same areas of work, otherwise it will be a non-compete agreement, facing the old club's Breach of contract.
Dun Tai certainly will not abandon the breach of contract due to non-compete agreements. In 2015, it sued over a dozen former Dun & Bradstreet developers including Mo Lianghua and provided them with more social security contributions The company filed a lawsuit against the noncompete restrictions, including BoGeng Technology, Cheung Long 3D, the East, deep plowing technology, Asia tillage electronics, etc. Including Mo Liang Hua, Xin Wei, millstone, stone, core Wei, Qin a However, Dun Tai said that due to the careful planning of Mo Lianghua and other concealed illegal means, many lawsuits have not yet resulted in the final verdict at the moment.
In the case of Dun Tai and Xin Wei, the labor arbitration suit filed under the non-compete agreement is only the beginning. More importantly, the patent ownership between Dun Tai and Xin Wei and the trade secret litigation initiated by Dun Tai.
Nearly a hundred patents were 'abandoned' and commercial secret litigation was taking place
For high-tech chip companies, the patent is the crown jewel, trade secrets is the most important, while in Dundee and the letter Wei's case, both include the same.
In the early days of the founding of Xinwei, it claims to have more than 100 patents related to fingerprinting, driving and touch.Dunter said that most of these patents are actually from the pre-departure and post-employment period of these patents by Mo Weihua to Xinwei Technology Or other related companies on behalf of the application.
'According to the law, these patents should belong to job creation, application rights and patent rights should belong to Dun & Tung.' In this regard, Dun Tai formally filed a lawsuit in Shenzhen Intermediate People's Court in July 2016, After submitting the relevant evidence, the trial of the case has been completed and all the 18 core patent judgments filed by Dun & Bradstre are vested in Dun & Bradstreet.
After the Shenzhen Intermediate People's Court decided that all 18 core patents should be vested in Dun & Tung, Credit Suisse and its affiliates quickly revoked nearly one hundred other patents, resulting in Dunhuang being unable to get the above patents back through its inventions, Dunnett also led to the above technology can not apply for patent protection.
Hu Zhengda said that the revocation of nearly a hundred abandoned patents that originally belonged to Dun Tai would not be denied by Dun Tai to Xinwei and its affiliates. Even if Dun & Bradstreet did not authorize Dunhuang, Xinwei and its affiliates did not The right to produce products based on these patents, the follow-up must require the letter Wei and its affiliates compensation.
In addition, the industry is concerned about the commercial secret lawsuit of both parties.In November 2015, Dun Tai to Molly Wah and Shin Wei on suspicion of infringement of Dun Tai trade secrets, filed a lawsuit to the Shenzhen Intermediate People's Court.
Dun Tai believes that press-type fingerprinting technology is its lasted 3 years of research and development, and strict protection measures to protect, and Mo Lianghua used to serve as vice president of Dunhuang and R & D head of the position was obtained from the relevant staff Technology and further research and development, and then by the letter Wei product promotion to customers.Dun Tai believes that the defendant letter Wei infringed its trade secrets.
Although the commercial secret case was first tried and Dun Tai's claim was not supported, Dundee filed an appeal with Guangdong Provincial Higher People's Court and is still in the process of hearing the case.
Mo Lianghua believes that the letter Wei did not infringe Duntai's trade secrets.But Dun Tai said the industry with the basic facts can analyze and determine whether Mo Lianghua and Xin Wei infringed the business secrets of Dun Tai.Related situation: Xin Wei Affiliates (Millstones) were established in February 2015. In March, Mo Liang Hua resigned from Dun Tai and Xinwei was established in June. In just a few months, he applied for more than 100 patents and issued fingerprint products However, due to the fact that he took advantage of the position of R & D manager during his tenure of office in Taitung, he used various means to cover up the facts, resulting in extremely difficult investigations and verifications of the case. In addition, the complexity of commercial secret cases was the case of Correct ruling has increased the difficulty, leading to the first instance court of commercial secrets failed to correctly restore the facts in determining the facts.At present, the two cases of commercial secret litigation are still under way.
At this point, Dun & Bradstreet and its related companies and individuals litigation, including non-competition restrictions, infringement of trade secrets and patent ownership are still ongoing, there is no end and no settlement.
Xin Wei Wei right to do the current product, Dun Tai retains the chasing rights
Commercial rights protection is a long process, and in particular the fingerprinting technology involved in both cases has gone through a wave of upsurge. It is also precisely because of the above events that Dunlop missed a good chance of catching up in 2015 when the capacitive fingerprint identification burst .
Hu Zhengda said although the incident caused some trauma to the company, we did not stop, but actively stepped up efforts in the deployment of R & D resources in the field of capacitive fingerprint identification in a short period of time. Set up a research and development team in the field of fingerprint identification.
At present, Dun Tai already has a complete capacitive fingerprint identification product line, perfect capacitance detection and fingerprint patent, Coating, Cover solutions have been successfully mass-produced in the brand client.Of course, objectively speaking, due to the incident of Mo Lianghua Influence, Dun Tai missed the first wave of opportunities to cut into the fingerprint identification market, but Dun Tai's other optical fingerprint R & D team has achieved initial success and has been officially released on January 8 this year, the optical screen fingerprint products, is expected Will be mass production soon 2018 is also the development of optical fingerprint opportunities, vivo has released the industry's first screen fingerprint recognition phone.
Hu Zhengda stressed that the letter Wei products do now if the alleged patent infringement, letter Wei is not entitled to do, because at the time of the letter Wei patent applications at least to the present, according to Shenzhen Intermediate People's Court ruling belongs to Dun Tai.Therefore, no Dunlop authorized, Xin Wei is not entitled to the production of related products, the follow-up Dun Tai will also require the letter Wei compensation. At the same time and Mo Weihua and letter Wei's litigation has not yet ended, around Mo Lianghua, Xin Wei infringement as the center Of the relevant disputes, including patent ownership, non-competition restrictions, trade secrets, nearly 40 lawsuits are being heard.
Finally, Hu Zhengda said that the fingerprint chip is a high-tech industry barriers, technological evolution from generation to generation is also very different, just have the funds not to research and develop more methods to focus on.Industry sources said that in a rapidly changing market environment, due to violations Competing restrictions, suspected infringement of trade secrets and patent ownership and many other disputes Xuan Wei, but also how far it is doubtful.
Of course, regardless of the final outcome, we should view the facts in a fair and objective manner. Especially in the domestic semiconductor industry is in the golden period of development, the maintenance of fair facts is also a benign guide to the entire industry. Wei's dispute.

2. China's selection of high-end talent to join the military focus on artificial intelligence and quantum technology;
Hong Kong media said that according to media reports, the PLA's top research institutes have collectively selected and dispatched more than 120 scientists who are in urgent need of scientific research. This is one of the efforts to develop the military applications of artificial intelligence and quantum technology.
According to the Hong Kong "South China Morning Post" website reported on January 26, according to the "Liberation Army Daily" reported that the Academy of Military Sciences focused on the entire army more than 120 urgent need for scientific research personnel in place.
Reported that the selection of researchers, with doctoral degree qualifications more than 95%, but also in some areas, especially smart unmanned, quantum technology has expertise.
Analysts said the election is part of China's efforts to become a superpower of military technology and to catch up with the technological superiority of the U.S. Armed Forces.
Colin Valley, a military expert on maritime security at the Sri Rajeeon Institute for International Studies in Singapore, said: "The Chinese People's Liberation Army is exploring these technological fields under the inspiration of the United States or the entire West."
'China's long-term desire is to stay on the same plane with these leaders in military technology, both for national defense purposes and for realizing its own position as a global arms supplier.'
He also said that China hopes that a technological breakthrough can confront the U.S. military dominance in the Asia Pacific region.
He said: 'China's exploration into these fields of military technology is also in line with its military strategy and posture. The strategy and the situation are expected to offset, through asymmetrical measures, the overall U.S. military advantage in the foreseeable crisis areas such as the Taiwan Strait. '
According to the report, a team led by Pan Jianwei at the University of Science and Technology of China is one of the teams leading the study of quantum technology in China, and quantum technology research can be exploited as scientists understand the world's principles of functioning at the subatomic level Some applications
Analysts believe that if China manages to exploit any breakthrough in quantum technology for the armed forces, it can gain military advantage.
Ben Ho, a researcher on the military research project at Nanyang Technological University in Singapore, said: 'One of the important benefits is that it enables users to have more sensitive sensors and thus has a better sense of the environment.'
He said: 'Information is the king of modern warfare, and having a better picture gives you a clear advantage over your opponent, after all, you can not fight what you can not see.'
Ho added that quantum technology and computers will also help crack the adversary's cryptographic code in the coming years.
3. Chinese and American scientists use graphene system to explore new ways of processing quantum information;
Xinhua News Agency, Hefei, January 28 The reporter learned from the University of Science and Technology of China that Guo Guoping, a professor at the university, Deng Guangwei, an associate researcher, and Tian Lin, a professor at the University of California, Merced, The pioneer of introducing the third harmonic oscillator as the phonon cavity mode has successfully realized long-range strong coupling and created the conditions for storing and transmitting quantum information using the phonon mode as the carrier. International Journal of Nature 1 The result was released on the 26th.
The nanometer harmonic oscillator has the advantages of small size, good stability and high quality factor, and is an excellent carrier for information storage, manipulation and transmission. Both classical and quantum information can be encoded in the phonon state of the harmonic oscillator, and the phonon state can also be used In order to realize this scheme, one of the major challenges is how to realize tunable phonon interaction over long distances. In recent years, the international academic community has tried to use the optical cavity or the superconducting microwave cavity as the medium for transmitting coupling. However, due to the difference in frequency Huge and coupling strength is usually small, it is difficult to achieve a strong coupling range.
In response to this challenge, Guo Guoping's research group proposed the idea of using the resonator itself as a phonon cavity cavity instead of a cavity or a microwave cavity, and designed and prepared a series structure of three graphene nanometer resonator. In this device, The resonance frequency of each resonator can be greatly adjusted by the metal electrode at the bottom of each resonator.It has been experimentally proved that the adjacent resonators can reach the strong coupling region in the series structure and when the frequency of the intermediate resonator is adjusted to be close to both ends of the resonance When the resonant frequency of the son, there is a great mode splitting between the two resonators, and the splitting value can be widely controlled by controlling the frequency of the intermediate harmonic oscillator.
Using the theoretical analysis of optical Raman process, the research team obtained the equivalent coupling strength of harmonic oscillators at both ends and their relationship with the detuning volume. The experimental results show that the measured equivalent coupling is in good agreement with the theoretical results.
According to reports, the experiment for the first time to achieve a non-neighbors in the graphene nanoshelf resonator coupling, for the study of mechanical and electrical harmonic oscillator has an important impetus for the phonon mode as a carrier for storage and transmission of quantum information to create the conditions.
4. From quantum dots to quantum ring changes more than one word
Quantum computing has become one of the hottest research projects nowadays, and the implementation of quantum bits as an information carrier is a key technology in quantum computer research.
Recently, researchers from the Institute of Microelectronics, Chinese Academy of Sciences, and Inspur Electronic Information Industry Co., Ltd. jointly published research papers jointly by Chongqing University of Posts and Telecommunications and Xiamen University, put forward the theoretical assumption of constructing quantum computers with multi-electron semiconductor quantum rings, Quantum bit implementation.
As the author of the article, Wu Zhenhua, a researcher at the IC R & D Center of the Institute of Microelectronics of the Chinese Academy of Sciences, said in an interview with Science and Technology Daily: 'The construction of quantum bits with a semiconductor quantum ring is a new idea based on the existing mature semiconductor technology to build a quantum computer '
The transistor size is close to the physical limit
In the recent 40 years, the microelectronics industry has followed the prediction of Moore's Law and has continued its rapid development.
But with the progress of technology, device integration is higher and higher, the number of transistors on the chip more and more, a single transistor size smaller and smaller.Can be said that the current semiconductor chip development has been close to the size of the physical limits, Moore's Law era is coming to an end, the urgent need to develop new computing principles and new device architecture to meet the growing computing needs. 'Wu Zhenhua explained that' in this context, scientists from all over the world vigorously study the laws of quantum mechanics, the development of quantum computing and quantum Information technology, in order to develop a practical computer that can replace the traditional computer quantum computing, super high quantum parallel computing power.
Quantum computers increase computational power by stacking and entangling quantum phenomena, which allow quantum bits to have values of 0 and 1 simultaneously for 'synchronous computation.' With each additional quantum bit, computational performance doubles . "Another author of the paper, Dr. Liu Yu, Inspur AI and HPC said.
At present, Google, Microsoft, IBM, Intel and other technology companies have laid out quantum computing research.Liu Yu said that IBM claims to have successfully developed a 50 qubits bit prototype; Quantum hardware leader Google Google John Martins Then in October last year revealed that Google already has 22 qubits of chips; China also released in early May 2017 the world's first quantum computer beyond the early classical computer, the successful realization of the 10 superconducting quantum bit entanglement is expected in the near future The future can be manipulated 20 superconducting qubits.
Meet a few specific 'indicators' to be more good
Quality quantum bit implementations typically need to meet several specific requirements, such as easier physical implementation of the vector, easier initial preparation and manipulation, longer coherence times, and more.
At present, the implementations of quantum bits mainly include superconducting loops, trapped ions, semiconductor quantum dots, diamond vacancies, topological arbitrary molecules, photons, etc. Each of these technologies has its own advantages and disadvantages. The final route in the future is not yet clear Wu Zhenhua told reporters.According to him, the above program, the semiconductor quantum dot program has the most core advantages, which can make use of existing semiconductor technology based on the development, operation speed, easy to achieve high-density integration, which attracted many research institutions attention.
However, due to the strong quantum confinement effect in semiconductor quantum dots, the electron coherence time is short and the electronic entanglement is difficult. To solve this problem, we use the configuration interaction method to theoretically study the semiconductors including 3 to 6 electrons Quantum ring in the multi-electron state and found that the number of electrons in the quantum ring is different from the electron will be coupled to form different entangled state, and can be different with the applied magnetic field, electric field showing different characteristics in order to achieve quantum state regulation.In addition, Our research also systematically expounded the scheme of measuring the characteristics of quantum rings by optics, Liu Yu said.
Available with existing semiconductor technology
In the view of Wu Zhenhua and Liu Yu, constructing a quantum bit with a multi-electron semiconductor quantum ring is a new concept for the existing single-electron semiconductor quantum dot scheme.The main obstacle to quantum computing is that it is difficult to maintain the quantum state for calculation, Which means the coherence time is short.The research shows that compared with the semiconductor quantum dots, the confinement potential of the semiconductor quantum ring is easy to be adjusted and the electron coherence time is longer, which is conducive to more quantum bit manipulation.Quantum quantum dots can only conduct single electron spin Fine control of the experimental requirements difficult.Multiple electronic quantum ring using electronic hybrid quantum number and electron spin state quantum bits, so have more freedom to manipulate.In addition quantum dots, the electron is bound at zero Dimensional space.Electrons in quantum rings also have the freedom to orbital motion in quasi-one-dimensional space, providing new coding possibilities beyond the spin of such charges.
Not only that, like the semiconductor quantum dots, the quantum ring can also be realized by using the existing semiconductor process, so that the transition from the classical semiconductor chip to the quantum chip can be smoothed based on the prior art, "Wu Zhenhua said.
This new research result is still a fruitful result of the cooperation between industry, universities and research institutes. "Liu Yu said:" This study uses a more rigorous and accurate theoretical simulation method, but with a huge amount of computation. The Institute of Microelectronics and Inspur Group, Give full play to the wave of high performance computing in the field of the advantages of the two sides will continue to promote cooperation in the field of quantum computing to seek new breakthroughs.
