Wolfspeed Inc ea Durham, NC, USA - e etsang thepa ea silicon carbide (SiC) le lisebelisoa tsa semiconductor ea matla - e phatlalalitse tlhahiso ea khoebo ea lihlahisoa tsa eona tsa thepa ea 200mm SiC, e tšoaeang mohato oa bohlokoa morerong oa eona oa ho potlakisa phetoho ea indasteri ho tloha silicon ho ea ho silicon carbide. Kamora ho fana ka 200mm SiC ho khetha bareki, feme e re karabelo e ntle le melemo li ne li hloka tokollo ea khoebo 'marakeng.
Wolfspeed e boetse e fana ka 200mm SiC epitaxy bakeng sa thuto ea hang-hang eo, ha e pentiloe ka li-wafers tsa eona tse 200mm, e fana ka seo ho thoeng ke katleho e kholo le boleng bo ntlafetseng, e nolofalletsang moloko o latelang oa lisebelisoa tsa motlakase tse sebetsang hantle.
Ngaka Cengiz Balkas, ofisiri e ka sehloohong ea khoebo e re: "Li-wafer tsa Wolfspeed's 200mm SiC li feta katoloso ea bophara ba liphaephe - li emela tlhahiso ea thepa e matlafatsang bareki ba rona ho potlakisa 'mapa oa lisebelisoa tsa bona ka boits'epo. "Ka ho fana ka boleng bo bongata, Wolfspeed e nolofalletsa baetsi ba lisebelisoa tsa elektroniki ho fihlela tlhoko e ntseng e hola ea litharollo tsa silicon carbide tse sebetsang hantle haholoanyane."
Litlhaloso tse ntlafalitsoeng tsa parametric tsa 200mm SiC bare wafers botenya ba 350µm le seo ho thoeng se ntlafatsoa, doping e etelletseng pele indastering le ho ts'oana ha botenya ba 200mm epitaxy e thusa baetsi ba lisebelisoa ho ntlafatsa chai ea MOSFET, ho potlakisa nako ea ho ea 'marakeng, le ho fana ka litharollo tsa tlholisano, lisebelisoa tse phahameng tsa indasteri, lisebelisoa tse ling tsa matla a holimo, le lisebelisoa tse ling tsa motlakase. ho bolela Wolfspeed. Lintlafatso tsena tsa sehlahisoa le ts'ebetso ea 200mm SiC le tsona li ka sebelisoa lithutong tse tsoelang pele bakeng sa lihlahisoa tsa thepa ea 150mm SiC, feme ea eketsa.
"Khatelo-pele ena e bontša boitlamo ba nako e telele ba Wolfspeed ba ho sutumetsa meeli ea theknoloji ea thepa ea silicon," ho bolela Balkas. "Tlhahiso ena e bonts'a bokhoni ba rona ba ho lebella litlhoko tsa bareki, ho lekana le tlhoko, le ho fana ka motheo oa thepa o etsang hore bokamoso ba phetoho e sebetsang hantle haholoanyane bo khonehe."
