History
King Yuan Electronics was incorporated in 1987 and is headquartered in Hsinchu City, Taiwan, with its main production base in Miaoli; it listed on 2001-05-09. The company built itself as a dedicated, independent test house focused on wafer probing and final test, plus burn-in and system-level testing. In 2025 it divested its China operations, completing the sale of its Suzhou subsidiary on 2025-02-13. Annual revenue rose from NT$23.992 billion in 2023 to NT$26.856 billion in 2024 and NT$34.934 billion in 2025.
Industry position
King Yuan Electronics is a pure-play third-party semiconductor test company; per its own website it is the world's largest professional independent semiconductor test house and the second-largest by test revenue. Its business is selling test capacity and hours rather than chips, with test services accounting for about 97% of revenue in the fourth quarter of 2025. It is positioned as a leader at the high-end test bottleneck, with Taiwan peers including 欣铨 and 矽格, and broader references such as Powertech (力成), ASE (日月光) and Amkor.
