2. About Polished Wafer

High-purity electronic grade polysilicon undergoes the steps of crystal pulling, slicing, beveling, lapping, etching, polishing, and cleaning to produce a polished wafer, which meets electrical, surface physical properties, impurity standards and other specifications. Wafers with special processes such as annealing, epitaxy, and SOI are processed based on polished wafers.

Polished wafer (PW) is a silicon chip with atomic flatness that is single side or double sides polished silicon wafer, accounting for about 70% of silicon wafer applications. After the monocrystalline silicon ingot is produced, it is cut into thin slices from the cylindrical monocrystalline silicon of the ingot, which is a wafer of high-purity silicon element. The purpose of polishing is to further remove the residual damage layer on the processed surface. The polished monocrystalline silicon wafer can be directly used to fabricate devices or as an epitaxial substrate material. Polished Si wafer is widely used in digital and analog integrated circuits, memory, power devices and other chips.
