UMC and Mei Guang tort lawsuit for more than 1 years in dispute, the mainland Fuzhou Intermediate People's Court to the United States to prohibit the light, to the United States and UMC patent infringement proceedings, the cessation of the United States Light Semiconductor (xian) and the United States Optical Semiconductor (Shanghai) products production and sales, temporarily from UMC next wins. But the immediate news of the mainland's verdict is a matter of concern. The two sides have already turned into an outpost of the US-China trade war, from the outset, from the start of the US-China optical-power-blocking scheme. UMC 3rd issued a notice, the mainland Fuzhou Intermediate People's Court has made a ban on the United States, in UMC patent infringement proceedings, the United States Light Semiconductor (xian) and the United States and Light Semiconductor (Shanghai) 12 items and 17 products must stop production and sales. At present only preliminary judgment, the United States and light in the mainland can still appeal. However, it is worth noting that, in addition to UMC and the United States and light tort lawsuit against the first confrontation has been considered by the market is the U.S.-China trade war outpost, both sides of the future battle plot climax can be, at the same time the lawsuit will affect the development of continental memory and the global Memory layout shuffle And from the UMC and the United States light confrontation process, has not been a mere tort case, the two sides of the duel represents the significance has been extended to the U.S.-China trade war and the mainland semiconductor Li Shi warlords. The first can be traced back to the 2015, in large funds backed by the group is interested in 23 billion U.S. dollars to acquire the United States light, fast-pulling memory research and development strength, but finally rejected, the mainland in 2016 fully accelerated the development of memory, including UMC and Fujian Jinhuagong signed DRAM Technical Cooperation Development Agreement, followed by the purple and large funds to jointly fund the establishment of the Yangtze River storage, Hefei Chang Xin also announced the investment of 50 billion yuan to build a wafer factory, 3 large memory plant to shoulder the development of the mainland DRAM and 3D NAND technical task. Market analysis pointed out that the mainland in recent years to develop the semiconductor industry, 2014 set up a "national Integrated circuit Industry Investment Fund" (large Fund), the first phase of funds up to 130 billion yuan, the recent 300 billion yuan silver bullet will be loaded, the scope of support including IC design, memory, Wafer foundry and testing industry chain, the recent U.S.-China trade war more accelerated the mainland government to fully develop semiconductor development. The mainland Fuzhou Intermediate People's Court of the United States to ban the light, can be said to be a good stone, in addition to the U.S.-China trade war to make a strong return, but also for the development of the mainland's semiconductor moat, to increase the future patent war chips on the hand. Mainland China with a large domestic market advantage, the first to take the mainland revenue is not low proportion of the United States light case surgery, warning Samsung Electronics (Samsung Electronics), SK Heidelberg (SK Hynix) and other international semiconductor manufacturers means strong, because the mainland semiconductor industry strength and international manufacturers still have a significant gap, Memory is still in the beginning, the current mainland government set 2019 as the first year of DRAM, so long as can advance the research and development process, any tricks is a good strategy, when there is no loss, the mainland to take a chance to nurture the heart of semiconductors, will be the global semiconductor layout shuffle time acceleration. Semiconductor manufacturers believe that UMC and the United States and light competition, who won the big, can be seen from their own advantages. In the light of the United States, the United States and light in the world's third largest memory plant, revenue ranked second only to Samsung and SK Rexroth, but it is worth noting that the mainland's revenues of about 50%, highly dependent on the mainland business is very deep, the United States light by the Fuzhou court quickly determine infringement, and issued a ban on production and sales, fear will bring heavy damage to its operations, Even though the future of the United States will retaliate in the US, but because the current mainland DRAM industry is still only in the beginning, there is no loss, but it has a large domestic market, in contrast, UMC behind the mainland government strong backers, the infringement of the United States light attack point is too weak, the loss will be higher than expected. For UMC, "binding" with the mainland continues to deepen, from Suzhou and the ship, Xiamen United core to the Shandong United 暻 Design and manufacturing layout, as well as with the Fujian Jinhuagong Technical Cooperation Agreement, and the United States and the light of the memory products infringement case, UMC did not choose to mention in Taiwan, but in January to the mainland Fuzhou court to Sue, The latest planned and ship A-share listing case, are prima facie UMC real implementation of the mainland wafer foundry business in the land strategy, with the mainland government to nurture the memory industry, and in the U.S.-China trade war, intends to use the United States to contain the U.S. offensive, the mainland government's UMC, borrowed force to force the force can be expected to fight back. It is noteworthy that the mainland has fully developed the semiconductor industry, it is generally believed that the memory to see, from scratch, the mainland faced with a patent-owned Samsung, SK, and other international manufacturers such as the United States, fear will encounter a number of patent lawsuits, development is not as good as expected, but the latest situation has been reversed by the mainland, with huge domestic demand advantages, The mainland to UMC, the United States and light tort cases, warning Samsung, SK Heidelberg and other manufacturers are obvious intentions, if any suppression of the mainland semiconductor development means, will retaliate at all costs, at least in the mainland any sales and marketing strategy will be stopped.
