Company Profile

Established in 2018, Unikorn Semiconductor Corp. specializes in providing compound semiconductor foundry services. Unikorn was formed when EPISTAR Corporation, the leading global supplier of LED chips, split from its internal foundry division and established an independent company based on its own core technology. GCS Holdings, Inc. has been an important strategic partner of Unikorn since Unikorn inception. GCS Holdings’ vast experience and advanced manufacturing technology in terms of III-V compound semiconductor communications and optoelectronic component foundries are critical in assisting Unikorn to expand its foundry services.

With the merger of two major LED corporation groups, EPISTAR and Lextar Electronics, in 2021 to establish Ennostar Inc. (Stock Code: 3714), Unikorn became one of the three largest subsidiaries of the Ennostar Group. Unikorn took on the crucial task of being“ the N0.1 investment platform for compound semiconductors” for Ennostar Group through its core work in providing compound semiconductor foundry services.

Unikorn’s foundry services include epitaxy and wafer/chip processing, with applications in sensors, 5G communications, displays, and power outputs. As per the different requirements of clients, Unikorn provides optimal manufacturing parameters and production platforms to satisfy the client’s delivery deadlines, yield, and customized design. In addition, Unikorn protects the rights and interests of clients by strictly adhering to the highest standards of quality. Unikorn is the ideal partner to allow clients to expand in the market and manufacture products.

Core Technology

Unikorn’s technical team has over 20 years of compound semiconductor manufacturing experience. We provide advanced manufacturing foundry services through four- and six-inch epitaxial wafers, with production including infrared VCSEL (sensors, optical communications), micro LEDs (displays), PIN/APD (optical communications), gallium (III) nitride (GaN) power components, radiofrequency (RF) components, and bulk acoustic wave (BAW) filters.

Unikorn’s comprehensive foundry services enable the simplification of feeding raw materials into different stages of production, reducing the length of time spent at the foundry stage and allowing for rapid responses to client requirements. In addition, Unikorn is equipped with a special technology platform that aids clients in reducing the size of package modules and end products, improving heat dissipation efficiency, expanding the operating range of driving currents, and enhancing the optoelectronic properties of products. By doing so, Unikorn creates new value and enhances competitiveness in client products.
