EPi Business Summary

Episil-Precision Inc. (EPi) is a premier Taiwan-based semiconductor manufacturer specializing in the research, development, and production of silicon and compound semiconductor epitaxial wafers. The company generates revenue primarily through the sale of high-performance epitaxial products, including buried-layer, multi-layer, and silicon-on-insulator (SOI) wafers, as well as wide-bandgap (WBG) materials such as Silicon Carbide (SiC) and Gallium Nitride (GaN). Its business is strategically segmented into silicon epitaxy—serving power management ICs (PMICs), MOSFETs, and IGBTs—and compound semiconductor epitaxy, which targets high-growth applications in electric vehicles (EVs), AI data centers, and 5G infrastructure. EPi is currently scaling its 8-inch wafer production capabilities to maintain its competitive edge in technical performance and cost-efficiency. In the global market, EPi competes directly with major players such as Wafer Works (6182.TW), GlobalWafers (6488.TW), and uPI Semiconductor (6719.TW), positioning itself as a specialized leader in advanced epitaxy services for the power semiconductor industry. The company’s leadership is headed by Chairman Jian-Hua Shyu, a semiconductor industry veteran with a distinguished pedigree from United Microelectronics Corporation (UMC) and Hwa-Jie Technology (HJTC). President Jin-Xiang Wen (Wen Js), who assumed his role in March 2025, brings extensive technical and operational expertise from his previous leadership tenures at Unikorn Semiconductor and HannsTouch Solution. The executive team is further supported by Vice President and Spokesperson Amy Fan and Director Chris Chen, a materials science expert and former Technology Director at TSMC. EPi operates as a key subsidiary of Episil Technologies Inc., which maintains a controlling stake of approximately 57.86%, ensuring robust strategic alignment and industrial backing. The board of directors is characterized by a diverse mix of semiconductor engineering and financial management expertise, featuring representatives from Hermes-Epitek and independent directors with deep roots in Taiwan’s electronics ecosystem.
