◼ Documented marks

01

Chairman of ASE Technology Holding Co. (NYSE: ASX; TWSE: 3711), the world's largest independent semiconductor packaging and testing company, processing chips for Qualcomm, AMD, Broadcom, MediaTek, and most major chipmakers; ASE's facilities in Kaohsiung, Taiwan, and across Asia handle packaging for a significant share of the world's advanced chips.

In November 2013, Taiwan's Environmental Protection Administration (EPA) discovered that ASE's Zhongli/Kaohsiung plant was discharging high-concentration metal-laden industrial wastewater into the Houjing River (鳳山溪), contaminating the waterway and killing fish; the Taiwan EPA ordered a production suspension at the facility. ASE was fined and required to implement wastewater treatment upgrades before resuming operations.

ASE's 2018 merger with USI (Universal Scientific Industrial) created ASE Industrial Holdings, which combined semiconductor packaging with electronic module manufacturing for automotive, IoT, and communications applications; the combined entity employs 95,000+ people globally, making ASE one of the largest private-sector employers in the global semiconductor supply chain.
