micronet news, in December 2017, Micron Technology filed a civil lawsuit in California, accusing UMC and Fujian Jinhua of infringing DRAM business secrets. In response, UMC made a counterattack today, filing lawsuits with the Fuzhou Intermediate People's Court against Micron Semiconductor (Xi'an), Micron Semiconductor Sales (Shanghai), Xiamen Siming District Xintongyuan Computer Business Department, Xiamen Antaisheng Electronic Technology and other companies filed three lawsuits, requesting compensation totaling RMB 270 million.
In addition, UMC requested the court to order the relevant defendants to stop manufacturing, processing, importing, selling, and offering to sell the accused infringing products, and to destroy all inventory and related molds and tools.
It is reported that UMC not only accused Micron of infringing on multiple of its patents, but also claimed that Micron manufactured, produced and sold Crucial DDR4 2400 8G notebook computer memory, Crucial MX300 2.5-inch SSD 525GB solid state drive and Colorful iGame1080 Flame God of War X-8GD5X The graphics memory chip in the graphics card is suspected of infringing UMC's patents in mainland China.
UMC stated that the company has long invested a lot of resources and manpower in the research and development of semiconductor manufacturing technology, and the results are used in logic chips or memory chips (DRAM). Over the years, it has applied in various countries and obtained multiple patents. It also continues to pay attention to the company's patents in the market. status. Micron is a well-known international company. In the past year, Micron has been making frequent moves against UMC, apparently exaggerating the disputes between Micron and its resigned employees into corporate infringement, and sued UMC in the United States. After an in-depth review, UMC found that Micron's products sold in mainland China infringed on UMC's patent rights. Therefore, it filed a patent infringement lawsuit in mainland China, hoping to obtain a fair judgment.
In fact, the dispute between Micron and UMC dates back to last year. In May 2017, UMC announced a contract with Fujian Jinhua Integrated Circuit Company. UMC accepted Jinhua's entrustment to develop DRAM-related process technology. Regarding the cooperation between UMC and Jinhua, the Taiwan District Prosecutor's Office investigated that Jinhua provided US$300 million in funds to purchase R&D equipment, and paid UMC US$400 million in succession according to the progress. The development results were shared by both parties. After the overall technology was completed, it was transferred to Jinhua For mass production.
In September 2017, the Taichung District Prosecutor’s Office discovered that employees surnamed He and Wang from Taiwan Micron had switched jobs to UMC and were suspected of leaking Micron DRAM technology to UMC to help UMC develop 32nm DRAM. The design rules can be completed quickly, violating the Business Secrets Act, etc. The suspects were prosecuted by men surnamed He and Wang, UMC's associate manager surnamed Rong, and UMC.
Subsequently, at the end of 2017, Micron Technology filed a civil lawsuit in California, accusing UMC and Fujian Jinhua of infringing DRAM business secrets.
