UMC today issued the following statement in response to an indictment (United States v. United Microelectronics Corporation, et al., CR 18 465 (LHK/SVK)  and civil complaint (United States v. United Microelectronics Corporation, et al., 18 CV 06643) unsealed on November 1, 2018 by the United States Attorney’s Office for the Northern District of California.

The indictment and civil complaint allege that starting in 2015 UMC and others conspired to steal trade secrets of another company, Micron Technology, Inc., and used that information to develop technology that was subsequently transferred to Fujian Jinhua, a Chinese company. The allegations in the indictment and complaint are virtually the same as allegations in a civil complaint previously filed against UMC by Micron. UMC regrets that the U.S. Attorney’s Office brought these charges without first notifying UMC and giving it an opportunity to discuss the matter.  

UMC is an industry-leading Taiwanese semiconductor company that has been developing integrated circuits and other technologies for four decades. It devotes vast resources to researching and developing technologies and owns a portfolio of thousands of active technology patents worldwide. UMC takes seriously any allegation that it may have violated any laws and fully intends to respond to these allegations accordingly.
