United Microelectronics Corp (UMC, 聯電) pledged “substantial assistance” to the US in a high-profile trade-secrets prosecution of Chinese chipmaker Fujian Jinhua Integrated Circuit Co (福建晉華).
UMC on Wednesday pleaded guilty in a San Francisco federal court in a deal with US prosecutors, who agreed to drop charges of economic espionage and conspiracy for the alleged theft of proprietary information from Idaho-based Micron Technology Inc.
UMC instead admitted to trade-secret theft and agreed to pay a US$60 million fine, the second-largest ever in a criminal trade secrets prosecution in the US.
The case was the first filed under the “China Initiative” of US President Donald Trump’s administration, a US Department of Justice program aimed at prioritizing trade-theft cases and litigating them as quickly as possible.
With UMC removed as a defendant, China becomes the target as tension with the West is aggravated by issues that include Beijing’s hacking and control of key technologies, its handling of the COVID-19 outbreak, tightening grip over Hong Kong and treatment of Muslim Uighurs.
“UMC’s guilty plea points this case toward trial against Fujian Jinhua in 2021,” US Attorney David Anderson said. “Criminal trade secrets cases protect freedom and innovation. These cases have global significance when a foreign defendant is charged with stealing intellectual property protected by US law.”
Prosecutors have not publicly detailed the cooperation that they are seeking from UMC against Fujian Jinhua. UMC declined to answer questions.
Investigations into three UMC employees who are allegedly involved in the case would continue, the justice department said.
According to the evidence admitted in connection with the guilty plea, the three employees — Steven Chen (陳正坤), Ho Chien-ting (何建廷) and Wang Yung-ming (王永銘) — all worked at Micron Taiwan before joining UMC.
Chen, who had been president at Micron Taiwan and was made senior vice president at UMC, brokered a deal with Fujian Jinhua to develop DRAM technology for the Chinese firm.
He then recruited Ho and Wang, who were still working at Micron as engineers, to join UMC.
Prior to leaving their jobs, Ho and Wang stole trade secrets from Micron and took them to UMC.
Wang, in particular, made adjustments to the DRAM technology they were developing at UMC based on the confidential information from Micron, the justice department said.
After UMC’s IT department found the stolen property on Ho’s computer, Chen approved the issuance of two “off network” laptops that allowed UMC employees to access confidential Micron information without being detected by UMC’s IT department.
When Taiwanese authorities began investigating the case, Ho and Wang asked another UMC employee to hide “papers, notes, USB drives, a personal phone and a laptop computer while the local authorities executed their search warrants,” the justice department said.
The justice department in 2018 formally charged UMC and Fujian Jinhua, as well as Chen, Ho and Wang, with crimes related to conspiracy to steal, convey and possess stolen trade secrets from a US firm.
UMC yesterday said that the company was glad to have reached an agreement with the US government.
“UMC takes full responsibility for the actions of its employees and we are pleased to have reached an appropriate resolution regarding this matter,” it said in a statement.
Micron said in a statement that it would continue to seek “full restitution” from UMC in a separate, ongoing civil lawsuit.
Neal Stephens, a lawyer for Micron, told US District Judge Maxine Chesney that with the resolution of the criminal case against UMC, Micron would push forward with its civil trade-secrets case against the company, which had been put on hold.
UMC has opposed reopening the case, Stephens said.
Still unknown is how much more money UMC might ultimately pay. In addition to the US fine, Micron would seek to make UMC pay restitution for the loss and damages caused by the theft.
The firms agreed that the sum would be argued in the civil suit, because there is a “great gulf and disparity” between what the two sides believe the value to be, said Leslie Caldwell, a lawyer for UMC.
A lawsuit against UMC in Taiwan about the same matter is still ongoing.

COMMUNICATION: A US representative said that Starshield is inactive in and around Taiwan, which could put US military personnel at risk in the Western Pacific in a conflict Space Exploration Technologies Corp (SpaceX) might have contravened its Pentagon contract by not providing access to its satellite communication network Starshield in and around Taiwan, a letter from a US House of Representatives committee to the company said. In September last year, the US Department of Defense awarded SpaceX a one-year contract for Starshield access, worth US$100 million. A few months before that, the Pentagon also commissioned SpaceX’s Starlink satellite network to be used by Ukrainian forces amid Russia’s invasion. Starshield is a derivative of Starlink intended for military use. SpaceX has long worked closely with the US military and intelligence agencies, which
SEEKING CALM: The US called for maintaining the ‘status quo,’ while the Ministry of National Defense said it would not bolster defenses in the area to avoid raising tensions Taiwanese should have greater faith in the government’s investigation into the capsizing of a Chinese vessel that resulted in the death of two Chinese fishers last week, the Coast Guard Administration (CGA) said yesterday, adding that Taiwan abides by the rule of law. On Wednesday last week, a Chinese speedboat was spotted trespassing in “prohibited” waters within 1.1 nautical miles (2km) of the east coast of Kinmen. It fled after refusing the coast guard’s request to board the vessel, setting off a chase that led to the boat capsizing, with two Chinese fishers dying. Two survivors were deported back to China
KINMEN: Coast guards on both sides of the Taiwan Strait should prohibit the entry of illegal vessels into ‘restricted’ waters to uphold maritime safety, Chen Chien-jen said Premier Chen Chien-jen (陳建仁) yesterday called for both sides of the Taiwan Strait to approach the security of Kinmen and Xiamen waters with rationality and equitability, following a boat chase that resulted in the death of two Chinese fishers last week. Chen was responding to media inquiries ahead of a legislative session amid rising cross-strait tensions following the capsizing of a Chinese speedboat off the east coast of Kinmen on Wednesday last week during a pursuit by the Taiwanese coast guard. The Ministry of National Defense established the boundaries of “prohibited” and “restricted” waters around Kinmen in 1992 to better protect
GREAT EXPECTATIONS: TSMC founder Morris Chang said he has high hopes for the new fab, based on his experience in Japan 56 years earlier, and amid high demand for AI Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) yesterday held an opening ceremony for its first chip manufacturing fab in Kumamoto, Japan, which it hopes will improve chip supply resilience and help Japan usher in a semiconductor renaissance. The Kumamoto fab is slated to enter volume production in the fourth quarter of this year. The Japanese government said it would extend its financial support of the project to include the construction of a second factory, as TSMC’s investment is crucial to its efforts to revive its semiconductor industry. The Kumamoto fab is owned by a joint venture, Japan Advanced Semiconductor Manufacturing Inc (JASM), which
