In the case of SiC at high temperatures, Si evaporates and causes surface roughness, so this is dealt with by forming a dense carbon film by sputtering. Ion Implantation for SiC WebHow SiC Wafers Are Made. Unlike the traditional silicon-based CMOS process, the manufacturing of SiC wafers is a batch process. Once a boule of SiC crystal is grown into individual wafers, they are loaded into a batch lapping system. The system reduces the thickness and makes the top and bottom surfaces parallel. list of scp doctors
