Company Profile

In response to the booming and strong market demand for III-V semiconductor component, Epistar (TWSE: 2448) split off the internal foundry division as an independent entity: Unikorn Semiconductor Corp. on October 1st, 2018. Unikorn is a professional III-V compound semiconductor foundry located in Hsinchu Science Park, Taiwan, and focuses on epitaxy and wafer/chip processing by providing corresponding process parameters and production platforms that meet customers’ unique specifications and technology requirements. Not only offers customers our professional and quality manufacturing service on lead time, yield and customized designs but also ensures the protection of intellectual properties, process recipe, and structural designs of our customers with the strictest standards.

With the development of new technologies and applications, III-V compound semiconductor markets grows rapidly. Unikorn has the proven ability to provide a comprehensive foundry services that meet these booming applications.

Sensing Applications: VCSEL、EEL
Datacom Applications: 10G/25G VCSEL, PIN, APD
Display Technology: Advanced LEDs (Micro LED)
5G applications: RF device, BAW filter
Others: GaN on Si power device & other III-V devices

In addition to standard process service solutions, Unikorn possesses other unique platform which combines the customer's design concept to create new product values and differences, and enhance product competitiveness. Assist customers in fulfilling their needs in different application areas and define the goal of "Actualize III-V semiconductors potential with excellent expertise and services".

Core Technology

Unikorn’s technical team mainly comes from Epistar Corporation and other silicon wafer foundry. With more than 20 years experience in the III-V semiconductor industry, Unikorn provides vertically integrated III-V materials epitaxial and advanced device processing in both 4-inch and 6-inch production lines.

In the epitaxy field, we are familiar with materials such as AlGaAs, AlGaInP, GaP, InP, AlInP, GaN, InGaP, InGaN, etc., which have wavelength ranging from 350 nm to 1000 nm. The part of wafer process, we provide a complete semiconductor process on a sub-micron scale. Total foundry solutions will simplify the process flow at different stage, reduce OEM cycle time and respond to customer needs quickly.

Unikorn not only provides standard process service solutions, but also possesses other unique process platform which we have developed before. The innovated technologies will provide the benefits of reducing dimension of package or terminal products, improving heat dissipation, and driving higher current. With the adjustment of opto-electro characteristics will increase the value or competitiveness for customer’s products.
