Epitaxial WafersManufacture and sales of Epitaxial Wafers including HBT, pHEMT, Diodes and VCSELs for wireless, semiconductor, optical, automotive and smart phone industries
Manufacturing, Marketing, and Selling of Epitaxial Wafers:
Compound semiconductor epitaxial wafers are used in a variety of commercial applications including: Mobile handsets, optical fiber communications, automotive LiDAR, and 5G systems. Sumitomo Chemical Advanced Technologies manufactures custom epitaxial wafers using MOCVD (Metalorganic Chemical Vapor Deposition) in our state-of-the-art facility in Phoenix, AZ.
From development to high volume manufacturing, our growth processes have been proven to produce wafers with the high level of uniformity and reproducibility necessary for demanding applications.
Our current capacity is >100,000 wafers/year
Our facilities in Phoenix include:
- A 50,000 sq. ft. building with over 6000 sq. ft. of clean room space utilized to produce gallium arsenide (GaAs) epitaxial wafers for the Compound Semiconductor market worldwide.
- 11 installed reactors with permits/expansion space for up to 19 reactors.
- Full characterization facilities including large area, quick turn device fab.
Research and Development:
In Phoenix, our dedicated engineering team is committed to providing development quantities of wafers for low volume or one of a kind applications. We have the experience needed to move from concept all the way to high volume manufacturing.
Our current capabilities include the following processes and products:
- LEDs (GaAs-based)
- Diodes (GaAs PIN, Schottky, Varactor, Gunn)
- InGaP HBT
- InP-based materials
