Wolfspeed Inc nke Durham, NC, USA - nke na-eme silicon carbide (SiC) ihe na ngwaọrụ semiconductor ike - ekwupụtala mmalite azụmahịa nke ngwaahịa ngwaahịa SiC 200mm ya, na-aka akara dị ịrịba ama na ebumnuche ya iji mee ka mgbanwe nke ụlọ ọrụ si na silicon gaa na silicon carbide. Mgbe mbụ enyechara 200mm SiC ka ịhọrọ ndị ahịa, ụlọ ọrụ ahụ na-ekwu na nzaghachi dị mma na uru ya nyere ikike ịhapụ azụmaahịa na ahịa.
Wolfspeed na-enyekwa 200mm SiC epitaxy maka ntozu ozugbo nke, mgbe ejikọtara ya na wafers efu 200mm, na-ebuga ihe a na-ekwu na ọ bụ scalability na mma dị mma, na-enyere ọgbọ na-esote ngwaọrụ ike arụ ọrụ dị elu.
"Wolfspeed's 200mm SiC wafers karịrị mgbasawanye nke dayameta wafer - ọ na-anọchite anya ihe ọhụrụ nke na-enye ndị ahịa anyị ike iji obi ike mee ngwangwa ụzọ ngwaọrụ ha," Dr Cengiz Balkas, onye isi azụmahịa.
