- Business
- ENNOSTAR Inc. (TWSE: 3714) engages in the research, development, manufacture, and sale of compound semiconductor-based optoelectronic products, with a vertically integrated supply chain spanning epitaxial wafers, LED chips, packaging, and modules. The company offers EPI wafers and chips including aluminum gallium indium phosphide (AlGaInP) and indium gallium nitride (InGaN) varieties; packaged light-emitting diodes (LEDs) for lighting, backlighting, displays, sensors, micro/mini LED applications; and advanced modules for automotive lighting and displays, smart sensing, advanced displays, and emerging AI optical interconnects and high-efficiency III-V solar cells. ENNOSTAR serves markets in displays, professional lighting, automotive, sensing, and high-value optoelectronics, operating primarily from Taiwan with sales across Asia including China, Hong Kong, Korea, Malaysia, Japan, Singapore, and international regions.
Founded in 1996 and headquartered in Hsinchu City, Taiwan, ENNOSTAR was established in January 2021 through a share swap merger between EPISTAR (formerly known as the company) and Lextar, creating a holding structure for upstream epitaxy/chip production via EPISTAR and downstream packaging/modules via Lextar. The company pursues a 3+1 long-term strategy targeting automotive, advanced displays, smart sensing, and emerging markets like optical communications, supported by subsidiaries including Unikorn Semiconductor for advanced compound semiconductor foundry.
In recent developments, ENNOSTAR announced in late 2024 the merger of subsidiaries EPISTAR and Lextar into a single entity tentatively named Ennostar Corporation, with a reference date of October 1, 2025, aimed at streamlining operations, enhancing efficiency, and accelerating growth in high-value optoelectronics without impacting parent shareholders' equity. Earlier in 2025, the company acquired ProLight Opto Technology Corp. through subsidiary WeiBang Investment to bolster microLED capabilities and align with its strategic focus areas. Additional partnerships include a September 2025 collaboration with X-Celeprint for silicon photonics integration and with Valeo for mini LED automotive exterior matrix displays launched at IAA Mobility 2025.
