Taipei, Sept. 6 (CNA) United Microelectronics Corporation (UMC), the second largest contract chip maker in Taiwan, and three of its employees were indicted Wednesday for violating the Trade Secrets Act and the Copyright Act.
UMC and the three individuals, surnamed Ho, Wang and Rong, allegedly illegally replicated Micron Technology, Inc. manufacturing techniques for the profit of UMC businesses in China, the Taichung District Prosecutors Office said in its indictment.
Ho and Wang are former employees of Micron Technology, where the former was a section chief and the latter a manufacturing deputy manager, prosecutors said.
In November 2015, Ho joined UMC where he became technical manager for special projects. Wang followed suit in March 2016, joining UMC as a technical manager for component parts, they said.
Ho is suspected of stealing classified trade information from Micron Technology and using it at UMC, thereby helping a UMC subsidiary manufacture computer memory wafers in China, according to prosecutors.
Wang, on the other hand, is suspected of stealing manufacturing technology and protocols and giving them to a UMC technical division associate, surnamed Rong, to speed up the design of UMC's process protocol, prosecutors said.
Micron Technology filed a suit after discovering that Wang had made electronic copies of company files and handed over to UMC.
Prosecutors searched UMC's Tainan plant in February this year.
It is reported that when Rong learned about the search, he instructed Ho and Wang to delete all related information from Micron Technology databases.
When questioned by prosecutors, Ho and Wang claimed that they took the data for personal research, while Rong said he only made suggestions to Wang on manufacturing design.
