Etch UNITY™ Series
The long-selling etch system has been receiving a lot of attention from the SiC market
The UNITY™ achieves excellent cost performance for plasma etch process within 200mm wafer, which provides exceptional reliability and productivity. Recent years, the system has a great deal and favorable approval through demonstration of high performance Si/SiC trench etch process for leading-edge power devices manufacturing.
UNITY™ Me+ is a successor to the UNITY™ Me dry etch platform that has received high acclaim for 200mm or smaller wafer processing. The renewal of UNITY™ Me in 2021 has significantly extended the support life for the product. The system can be configured with DRM and SCCM™ chambers for SiO2/SiN etch as well as chambers for Si/SiC trench etch. The system supports 100/150/200mm wafer sizes and has a track record of processing Si wafers as well as LT, LN, and other compound wafers. TEL uses an in-house demo tool to evaluate to solve customers’ process issues and achieve the required performance.
