Wolfspeed Inc ea Durham, NC, USA — e etsang thepa ea silicon carbide (SiC) le lisebelisoa tsa semiconductor tsa matla — e phatlalalitse ho qalisoa ha khoebo ha lihlahisoa tsa eona tsa thepa ea 200mm SiC, e leng se tšoaeang bohlokoa bo boholo morerong oa eona oa ho potlakisa phetoho ea indasteri ho tloha ho silicon ho ea ho silicon carbide. Kamora ho fana ka 200mm SiC qalong ho bareki ba khethiloeng, feme e re karabelo e ntle le melemo li ne li hloka hore ho lokolloe khoebo 'marakeng.
Wolfspeed e boetse e fana ka 200mm SiC epitaxy bakeng sa ho tšoaneleha hang-hang, eo, ha e kopantsoe le li-wafer tsa eona tse se nang letho tsa 200mm, e fanang ka seo ho thoeng ke bokhoni ba ho hola le boleng bo ntlafetseng, e nolofalletsang moloko o latelang oa lisebelisoa tsa motlakase tse sebetsang hantle.
“Li-wafer tsa Wolfspeed tsa 200mm SiC ha li felle feela ka katoloso ea bophara ba wafer – li emela boqapi ba thepa bo matlafatsang bareki ba rona ho potlakisa mekhoa ea bona ea lisebelisoa ka kholiseho,” ho bolela Ngaka Cengiz Balkas, ofisiri e kholo ea khoebo. “Ka ho fana ka boleng ka tekanyo e kholo, Wolfspeed e nolofalletsa bahlahisi ba lisebelisoa tsa elektroniki ho fihlela tlhoko e ntseng e hola ea litharollo tsa carbide tsa silicon tse sebetsang hantle le tse sebetsang hantle.”
Litlhaloso tse ntlafalitsoeng tsa parametric tsa li-wafer tse se nang letho tsa 200mm SiC ka botenya ba 350µm le seo ho thoeng se ntlafalitsoe, ho ts'oana ha doping e etelletseng pele indastering le botenya ba epitaxy ea 200mm ho nolofalletsa baetsi ba lisebelisoa ho ntlafatsa chai ea MOSFET, ho potlakisa nako ea ho ea 'marakeng, le ho fana ka litharollo tse hlōlisanang haholoanyane ho pholletsa le lits'ebetso tsa likoloi, matla a nchafatsoang, indasteri le tse ling tse holang haholo, ho bolela Wolfspeed. Tsoelo-pele ena ea sehlahisoa le ts'ebetso bakeng sa 200mm SiC e ka boela ea sebelisoa ho lithuto tse tsoelang pele bakeng sa lihlahisoa tsa thepa ea 150mm SiC, ho eketsa feme.
“Tsoelo-pele ena e bonts'a boitlamo ba nako e telele ba Wolfspeed ba ho sutumelletsa meeli ea theknoloji ea thepa ea silicon carbide,” ho bolela Balkas. “Ho qalisoa hona ho bonts'a bokhoni ba rona ba ho lebella litlhoko tsa bareki esale pele, ho hola ka tlhoko, le ho fana ka motheo oa thepa o etsang hore bokamoso ba phetoho ea matla e sebetsang hantle bo khonehe.”
