PHOENIX SILICON INTERNATIONAL Business Summary

Phoenix Silicon International Corp (PSI) operates a service-centric business model specializing in high-precision semiconductor wafer processing and energy solutions. The company generates the majority of its revenue through three primary segments: Wafer Reclaim services, which restore used test and monitor wafers for reuse; Wafer Thinning, providing critical back-side grinding and metalization for power semiconductors; and its Energy division, which manufactures lithium iron phosphate (LiFePO4) battery cells and packs. PSI occupies a vital niche in the semiconductor supply chain by enabling cost-reduction and sustainability for Tier-1 foundries and IDMs. It competes directly with specialized players such as Orient Semiconductor Electronics, Elite Advanced Laser, and Keystone Microtech, distinguishing itself through its integrated MEMS foundry capabilities and a dominant market share in the 12-inch wafer reclaim sector within Taiwan. The leadership team is anchored by Chairman Mike Liang (Ming-Cheng Liang), a veteran executive with a high-profile pedigree including former roles as President of King Yuan Electronics and Amkor Technology Taiwan, as well as Vice President at Micron Memory Taiwan. The executive suite is led by CEO and President Dr. Tony Tsai, who holds an Engineering Ph.D. from UC Berkeley and has overseen the company’s technical expansion for over seven years. Supporting them are Senior Vice President FN Huang and COOs Eric Pan and TK Huang, the latter bringing significant operational experience from Infineon. The company’s strategic direction is further influenced by a board featuring representatives from notable industrial investors, including Acter Group Co., Ltd. and Gallant Precision Machining Co., Ltd., ensuring deep alignment with the broader Taiwanese electronics manufacturing ecosystem.
