1.123 new three board companies IPO, these two semiconductor companies are worthy of attention;
According to the micro-net news, as 2017 financial reports are successively disclosed, new third-tier companies that are seeking IPO listing counseling will face embarrassing situations. If the performance is 'changing face' and there is no clear strategic plan, IPO is difficult to retreat. According to incomplete statistics on micro-nets, as of March 15th, there were 123 new three-board companies sprinting IPOs, of which there are two semiconductor companies, namely, core-micro, and Aschco’s.
Xinpengwei: Core Product Revenue Decreases Year by Year
Xinpeng Wei is an older domestic power management chip design company established in 2005. The company was listed on the new three boards in January 2014. The prospectus shows that Chongpeng Microelectronics intends to issue no more than 25.7 million shares on GEM, accounting for the issuance of shares. After the total share capital of 25%, it plans to raise funds of 220 million yuan for the development and industrialization of smart home power system management chips, new motor drive chips and module development and industrialization and R&D center construction projects. It is reported that the core friends micro IPO The sponsor institution is Hualin Securities.
During the reporting period, the core revenues of the core and microelectronics were 163 million yuan, 187 million yuan, 230 million yuan and 52.85 million yuan, and the net profit was 14.929 million yuan during the same period from January to June 2017. 2062.89 Ten thousand yuan, 300.513 million yuan and 6.073 million yuan.
As of the signing date of the prospectus, C&P Microelectronics had three wholly-owned subsidiaries and one shareholding company. In 2016, only Suzhou Bochuang achieved profitability.
According to the disclosure, the mobile digital chip is one of the core products of the core chip microelectronics. The sales revenue for the 2014-2016 and January-June 2017 sales was 83,315,800 yuan, 71.714 million yuan, 6,622,126 yuan and 1,208.90 million yuan, respectively. The proportion of main business income was 51.48%, 38.23%, 28.85% and 22.87%, respectively. During the reporting period, there was a drop in mobile digital chip revenue.
However, Xinpengwei is continuously investing in R&D support to increase its core technology accumulation. During the reporting period, C&P's R&D expenditure was RMB 24,941,600, RMB 31,175,600, RMB 41,116,250 and RMB 10,704,000, respectively, which accounted for the proportion of the company's operating income. They were 15.34%, 16.67%, 17.93% and 20.25%, respectively.
Xinpeng Wei said that the company's focus is constantly shifting to high-end product lines, from 'import substitution' to 'upgrading,' and actively from the home appliance market to drones, electric vehicles, charging piles, smart homes and other emerging market areas expand.
Axal Optoelectronics: Profits and Research & Development Rise Significantly Decline
According to public information, Aschwide was listed on the New Third Board on July 21, 2015. Its main business is the design, development, production, and sales of small and medium size liquid crystal displays and liquid crystal display modules. The company's main customers are the manufacture of end products. Businesses and their associated technical service providers are mainly distributed in Germany, the United States, Japan and China and other countries and regions.
According to the prospectus, ASG's performance in recent years is not stable. In 2015, 2016 and 2017, ASG achieved operating income of 385 million yuan, 398 million yuan and 242 million yuan, net profit of 61.1822 million yuan, 7759.17 Ten thousand yuan and 30.5732 million yuan.
It can be seen that Azbil’s revenue in 2017 both declined, which is not ideal. Axalore stated that the main reason for the decrease in net profit during the reporting period was that the company’s two touch-screen TFT products had large difficulty levels and low yields. 2. In the first half of 2017, the RMB exchange rate against the US dollar has been in a state of appreciation.
With the rapid development of the touch panel industry, technological evolution is also relatively fast. It also requires strong technical R&D support for ASG. However, it is difficult to understand that Aschwide’s R&D and technical personnel account for no increase. Reduced.
According to the public transfer specification (Feedback) disclosed by Aschoff in July 2015, as of December 31, 2014, the company had a total of 530 employees, of whom 165 were R&D and technical personnel, accounting for 31.13%.
According to the latest disclosure prospectus (submission draft) of Asch & Optoelectronics, as of the end of March 2017, the company had 1,693 employees, including 110 R&D technicians, accounting for 6.50%.
Under the background that revenues and profits have both declined, and the proportion of R&D technicians has been greatly reduced, it may be difficult to see the moment when Aschois IPO successfully passed the meeting.
2. China University of Science researchers successfully achieved single particle or cell capture;
Science and Technology Daily Hefei, March 16th (Reporter Wu Changfeng) The reporter learned from the University of Science and Technology of China that the micro-nano engineering laboratory of the School of Engineering Science of the university has made important progress in the field of single particle or cell capture research. They proposed using real-time femtosecond laser dual Photon lithography technology has successfully achieved the capture of single particles or cells. This technology can also realize the real-time capture of controlled multi-particles or cell clusters. It can be used for cell communication or interaction studies between particles and is expected to greatly promote cells. Capture the development of the research field. The research results were published in the microchip international laboratory "Chip Lab" recently, and were selected as the cover, and published by the "Photonics of Nature".
In single-cell analysis studies, capture of target cells is the first step in achieving single-cell analysis. Microfluidic chips have some advantages over traditional experimental methods and have been extensively studied and applied in the field of single cell capture. The microfluidic-based capture array method is the simplest and most commonly used method to achieve cell or particle capture separation. However, the current micro-capture arrays face several challenges: first, very low capture efficiency (below 10%); Secondly, it is impossible to achieve real-time controllability for the target structure size and geometry; furthermore, it is difficult to capture the controllable particle clusters at the same time.
The research team first designed and manufactured a certain degree of microfluidic chip, and introduced a photoresist or hydrogel containing the target microparticles or cells into the chip; real-time observation and screening of the target particles through the image, and then quickly controlled the liquid stoppage; Using a femtosecond laser to process the micropillar array around the target particle or cell; finally wash off the photoresist or hydrogel to get the target structure for subsequent single-cell analysis. The capture efficiency of a single cell or particle is close to 100%, and the capture target The geometric size and shape can be adjusted in real time. In addition, a controlled number of particle clusters can be captured.

Academician Fan Yanyuan, Director of the Selection Committee, and Academician Li Ruxin, Director of the Shanghai Institute of Optics and Mechanics, Chinese Academy of Sciences presented the awards to the representatives. And certificate. Prof. Huang Dongdong, Director of the Department of Electronics, Tsinghua University spoke as the winner.
Professor Huang Xiaodong made a speech.
The two results selected by Tsinghua University are:
Prof. Liu Fangdong, Professor of the Department of Electronics Huang Weidong of Tsinghua University, developed an on-chip integrated free-electron light source, and for the first time in the world realized the thresholdless Cherenkov radiation. This result subverts the form of the traditional free electron light source, and also makes flying research on the chip. The interaction between electrons and micro-nanostructures becomes possible.
Prof. Huang Xidong’s research group began research on micro-nanostructured optoelectronic devices in 2004. He has accumulated international leading advantages in micro- and nanostructured photoelectron physics and manufacturing processes, and test technology. Prof. Liu Fang, Associate Professor of the Research Group led the Ph.D. student Xiao Long et al. In the study of Cherenkov radiation in artificial hyperbolic metamaterials, it was found that in the hyperbolic metamaterial, no matter how slow the electrons are, radiation can be generated, ie, the thresholdless Cherenkov radiation can be realized.

In order to verify this major discovery, after more than two years of unremitting efforts, members of the research team have continuously overcome many bottlenecks in the fabrication and testing of nanostructures such as on-chip planar electron emission sources, hyperbolic metamaterials, and surface plasmon polariton slits. After electrons were emitted from a molybdenum tip with a radius of curvature of several tens of nanometers, a 40-nanometer straight-line flight of 200 micrometers was performed on the surface of the chip. Eventually, a non-threshold Cherenkov radiation was observed. The radiation wavelength is 500 to 900 nm, and the electron energy is only It is between 250 and 1400 electron volts, which is 2-3 orders of magnitude lower than the electron energy of hundreds of thousands of electron volts required for the same kind of experiments reported so far. The experiment yielded 200 nanowatts of radiant light output power, which was obtained with other nanostructures. Compared to Cerenkov radiation, the output power is more than 2 orders of magnitude higher.
Threshold Cherenkov radiation experimental results.
Tsinghua University's Department of Electronics Professor Ning Cunzhen's research group combined single-layered molybdenum diselenide with silicon-based nanoarm cavity and realized for the first time in the world a two-dimensional material nanometer laser operating at room temperature. This result is based on silicon-based lasers and excitons. Research on polarimetric lasers is of great significance.
The research group led by Prof. Ning Cunzheng from the Department of Electronics of Tsinghua University combined with the experience of nano-laser research carried out over the years, using a single layer of deuterated molybdenum with a thickness of only 0.7 nm as a gain material, with a width of only 300 nm and a thickness of more than 200 nm The silicon nanoarm cavity is used as a laser resonator. The research group found that in the above two-dimensional material, the binding energy of electrons and holes is very high, and a stable exciton state can be formed with high luminous efficiency. Silicon-based nanoarms The cavity has an ultra-high optical quality factor, and the exciton radiation wavelength of the molybdenum diseloxide has almost no absorption in the silicon material. Therefore, the combination of the “strong-strong” two-dimensional material and the silicon-based nanoarm cavity is to operate the laser. The important reason why the temperature is raised to room temperature.

The reticular structure shows a single layer of two-dimensional material, and underneath is a silicon nanocantilever used as a laser cavity.
This research requires the fabrication of a nanometer cantilever structure with precise dimensions and etching of one-dimensional circular hole arrays of different sizes on the cantilever. At the same time, the single-layered two-dimensional material is accurately transferred to the nano-cantilever structure. Nano-technology has brought great challenges. Professor Ning Cun-zheng led young teachers Li Yongzhuo and others to overcome a series of difficulties and finally realized for the first time in the world that the two-dimensional material nano-laser operates at room temperature.

The research on nano-laser is of great significance for basic research and practical application. First of all, two-dimensional material as the thinnest optical gain material has been proved to support laser operation at low temperature, but whether this single-layered molecular material is sufficient to support room temperature The laser operation still has doubts in the scientific and technological community. Room temperature operation is the premise of the practical application of most lasers. Therefore, the room temperature operation of the new laser has an index significance in the history of semiconductor laser development. In addition, due to the strong Coulomb in the two-dimensional material Interactions, electrons and holes always appear in exciton states, so this laser is actually closely related to a new type of exciton polariton Bose-Einstein condensate, which is the most active in the field of basic physics One of the topics.
The other eight major optical research advances in basic research categories are: Chaotic Highway, a photon momentum conversion discovered by Peking University; All-optical drive developed by the Shanghai Institute of Optics, Chinese Academy of Sciences, producing a 'micro-wavelength' of strong terahertz radiation. Nankai University uses a complementary light-absorbing strategy for oligomeric materials to construct a stacked organic solar cell device with broad spectral absorption characteristics; Sun Yat-sen University cooperates in designing a valley photonic crystal to obtain a new energy valley-strontium spin interaction and achieve Spin-spin and topology control; Southeast University realizes parity-time symmetrical quantum walk in open system, and observes new one-dimensional topology protection boundary state; Generalized magnetic mirror of National University of Defense Technology; Huazhong University of Science and Technology based on orbit resolution Atomic-scale molecular nuclear dynamics detection of high-order harmonic spectroscopy; Nanjing University found that three-dimensional Dirac semi-metal film material can be used as an ideal switch material for the preparation of high-performance mid-infrared pulsed lasers.
