Wolfspeed Inc nke Durham, NC, USA — nke na-emepụta ihe silicon carbide (SiC) na ngwaọrụ semiconductor ike — ekwupụtala mmalite azụmaahịa nke ngwaahịa ihe SiC 200mm ya, nke na-egosi ihe dị mkpa n'ọrụ ya iji mee ka mgbanwe ụlọ ọrụ ahụ site na silicon gaa na silicon carbide ngwa ngwa. Mgbe o buru ụzọ nye ndị ahịa ahọpụtara 200mm SiC, ụlọ ọrụ ahụ kwuru na nzaghachi na uru dị mma kwesịrị ka a wepụta ya n'ahịa.
Wolfspeed na-enyekwa 200mm SiC epitaxy maka asambodo ozugbo, nke, mgbe ejikọtara ya na wafers efu 200mm ya, na-enye ihe a na-ekwu na ọ bụ nnukwu nhazi na mma ka mma, na-eme ka ọgbọ ọzọ nke ngwaọrụ ike dị elu rụọ ọrụ nke ọma.
"Wafers SiC nke Wolfspeed nke 200mm karịrị mmụba nke dayameta wafer - ọ na-anọchite anya ihe ọhụrụ nke na-enye ndị ahịa anyị ike ime ka atụmatụ ngwaọrụ ha dịkwuo ngwa ngwa n'enweghị obi abụọ," ka Dr Cengiz Balkas, onye isi azụmaahịa kwuru.
