WebⅠ. Introduction. After the 1950s, four basic processes (ion implantation, diffusion, epitaxial growth, and lithography) were invented, and the semiconductor IC process was gradually developed.It is simple to harm the circuit function in the chip if it is polluted by dust particles and metals, generating a short circuit or open circuit, etc., resulting in the failure of the … WebJul 16, 2024 · By adding a layer of SiO 2 mask between SiC and the original metal mask together with ultrasonic cleaning and oxygen plasma cleaning process, the sample surface roughness was effectively reduced from 1.090 to 0.055 nm. Moreover, this method supplies a valuable reference for solving the problem of surface contamination caused by plasma …
