Why Pre-Diffusion Cleans Are Important for Silicon Wafer Cleaning

why-pre-diffusion-cleans-are-important-for-silicon-wafer-cleaning

Pre-diffusion cleans are carried out several times during the semiconductor manufacturing process, and each time the chemical residues and particles on the wafers have to be removed as completely as possible. If silicon wafers still have surface contamination when they are placed in the diffusion oven, diffusion may be uneven and the resulting semiconductor products […]
