Our Low Stress Nitride can be used for Membranes, Cantilever Beams, and other mechanical structures associated with MEMS devices. This Silicon Rich Film is excellent as a KOH Etch Mask. All silicon wafers have been thoroughly inspected and receive a pre-furnace clean prior to LPCVD Nitride deposition. All orders are sent with a Certificate of Conformance containing wafer specifications and Nitride film thickness data.
