Etching wafer

Brief introduction of 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.

The etching wafer is mainly applied in the diode/triode, thyristor, TVS products, IGBT, high-efficiency solar panel, etc.
