United Microelectronics Corp (UMC, 聯電) and Micron Technology Inc yesterday said they have settled a civil lawsuit in which the US memorychip maker accused the Taiwanese company of stealing and leaking its intellectual property to a Chinese partner.
UMC is to make a one-time payment of an undisclosed amount to settle all competing claims between the companies globally, a joint statement said.
UMC said that it did not expect the payment to have any significant impact on its financial status.

The move ends a high-profile chapter in tensions between the US and China, with the international case serving as a focal point for Washington complaints of Beijing facilitating forced technology transfers, a charge that China denies.
The case concerned an allegedly illegal transfer of Micron’s memory designs in a chip manufacturing deal between UMC and Jinjiang-based Fujian Jinhua Integrated Circuit Co (福建晉華).
Following the move, Micron said that it would continue to seek “full restitution” from UMC in a separate civil lawsuit, the statement said.
Last year, UMC pleaded guilty in San Francisco federal court in a deal with US prosecutors, who agreed to drop charges of economic espionage and conspiracy.
UMC instead admitted to trade-secret theft and agreed to pay a US$60 million fine.
Evidence submitted in connection with the guilty plea showed that the three workers — Steven Chen (陳正坤), Ho Chien-ting (何建廷) and Wang Yung-ming (王永銘) — were employed 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.
The US Department of Justice 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.
Three experts in the high technology industry have said that US President Donald Trump’s pledge to impose higher tariffs on Taiwanese semiconductors is part of an effort to force Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) to the negotiating table. In a speech to Republicans on Jan. 27, Trump said he intends to impose tariffs on Taiwan to bring chip production to the US. “The incentive is going to be they’re not going to want to pay a 25, 50 or even a 100 percent tax,” he said. Darson Chiu (邱達生), an economics professor at Taichung-based Tunghai University and director-general of
‘LEGACY CHIPS’: Chinese companies have dramatically increased mature chip production capacity, but the West’s drive for secure supply chains offers a lifeline for Taiwan When Powerchip Technology Corp (力晶科技) entered a deal with the eastern Chinese city of Hefei in 2015 to set up a new chip foundry, it hoped the move would help provide better access to the promising Chinese market. However, nine years later, that Chinese foundry, Nexchip Semiconductor Corp (合晶集成), has become one of its biggest rivals in the legacy chip space, leveraging steep discounts after Beijing’s localization call forced Powerchip to give up the once-lucrative business making integrated circuits for Chinese flat panels. Nexchip is among Chinese foundries quickly winning market share in the crucial US$56.3 billion industry of so-called legacy
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) yesterday held its first board of directors meeting in the US, at which it did not unveil any new US investments despite mounting tariff threats from US President Donald Trump. Trump has threatened to impose 100 percent tariffs on Taiwan-made chips, prompting market speculation that TSMC might consider boosting its chip capacity in the US or ramping up production of advanced chips such as those using a 2-nanometer technology process at its Arizona fabs ahead of schedule. Speculation also swirled that the chipmaker might consider building its own advanced packaging capacity in the US as part
Zhang Yazhou was sitting in the passenger seat of her Tesla Model 3 when she said she heard her father’s panicked voice: The brakes do not work. Approaching a red light, her father swerved around two cars before plowing into a sport utility vehicle and a sedan, and crashing into a large concrete barrier. Stunned, Zhang gazed at the deflating airbag in front of her. She could never have imagined what was to come: Tesla Inc sued her for defamation for complaining publicly about the vehicles brakes — and won. A Chinese court ordered Zhang to pay more than US$23,000 in
