Undoped Indium Arsenide Substrate, 4”, Test Grade

PAM-XIAMEN offers InAs wafer – Indium Arsenide which are grown by LEC(Liquid Encapsulated Czochralski) or VGF(Vertical Gradient Freeze) as epi-ready or mechanical grade with n type, p type or undoped in different orientation(111),(100) or (110). PAM-XIAMEN can provide epi ready grade InAs wafer for your MOCVD & MBE epitaxial application .Please contact our engineer team for more wafer information.

4" InAs Wafer Specification

What is the InAs Process?

InAs wafers must be prepared prior to device fabrication. To start, they must be completely cleaned to remove any damage that might have occurred during the slicing process. The wafers are then Chemically Mechanically Polished/Plaranrized (CMP) for the final material removal stage. This allows for the attainment of super-flat mirror-like surfaces with a remaining roughness on an atomic scale. After that is completed, the wafer is ready for fabrication.
