Silicon Wafer

Etching wafer

The etching wafer has the characteristics of low roughness, good glossiness and relatively low cost, and directly substitutes the polished wafer or epitaxial wafer which has relatively high cost to produce the electronic elements in some fields, to reduce the costs. There are the low-roughness, low-reflectivity and high-reflectivity etching wafers.
