Wafer manufacturing is the foundation of semiconductor and MEMS device production. From high-purity silicon preparation to slicing, grinding, polishing and inspection, each step affects the reliability and consistency of the final device.

A typical wafer workflow includes crystal growth, ingot slicing, edge processing, lapping, chemical treatment, CMP polishing and final cleaning. Strict control of flatness, surface roughness, thickness and contamination is essential for subsequent lithography and deposition.

MEMS fabrication adds further process requirements, including photolithography, etching, thin-film deposition, doping, wafer bonding and dicing. These processes create microstructures, functional layers, cavities and electrical features on or inside the wafer.

For R&D and pilot production, choosing the correct wafer material and process route can reduce trial-and-error cost and improve project efficiency. Important parameters include wafer size, crystal orientation, resistivity, thickness, surface quality and compatibility with downstream processing.
