Semiconductor Cleaning: Processes, Methods, and Principles

Since the invention of the four basic processes of ion implantation, diffusion, epitaxial growth, and lithography in the 1950s, semiconductor manufacturing processes have continued to develop. Chips are extremely susceptible to particle and metal contamination during production, leading to failures such as short circuits or open circuits. Therefore, in addition to strictly preventing external contamination throughout the entire production process, wet or dry cleaning is required before and after key manufacturing steps such as high-temperature diffusion and ion implantation.
