Wolfspeed Inc ntawm Durham, NC, Tebchaws USA — uas ua cov khoom siv silicon carbide (SiC) thiab cov khoom siv hluav taws xob semiconductor — tau tshaj tawm qhov kev tshaj tawm lag luam ntawm nws cov khoom siv 200mm SiC, cim lub hom phiaj tseem ceeb hauv nws lub hom phiaj los ua kom kev lag luam hloov pauv ntawm silicon mus rau silicon carbide sai dua. Tom qab pib muab 200mm SiC rau cov neeg siv khoom xaiv, lub tuam txhab hais tias cov lus teb zoo thiab cov txiaj ntsig tau lees paub kev tshaj tawm lag luam rau kev ua lag luam.
Wolfspeed kuj tseem muab 200mm SiC epitaxy rau kev tsim nyog tam sim ntawd uas, thaum ua ke nrog nws 200mm liab qab wafers, xa qhov uas tau thov tias yog kev nthuav dav thiab kev txhim kho zoo, ua rau tiam tom ntej ntawm cov khoom siv hluav taws xob ua tau zoo.
"Wolfspeed's 200mm SiC wafers yog ntau tshaj li qhov kev nthuav dav ntawm lub wafer txoj kab uas hla - nws sawv cev rau kev tsim kho tshiab ntawm cov khoom siv uas ua rau peb cov neeg siv khoom muaj peev xwm ua kom lawv cov cuab yeej siv tau sai dua nrog kev ntseeg siab," Dr Cengiz Balkas, tus thawj coj ua lag luam hais. "Los ntawm kev xa khoom zoo ntawm qhov ntsuas, Wolfspeed ua rau cov chaw tsim khoom siv hluav taws xob muaj peev xwm ua tau raws li qhov kev thov loj hlob rau cov kev daws teeb meem silicon carbide ua tau zoo dua."
Cov lus qhia txog kev txhim kho parametric ntawm 200mm SiC liab qab wafers ntawm 350µm thickness thiab qhov uas tau thov kom txhim kho, kev lag luam-ua doping thiab thickness uniformity ntawm 200mm epitaxy ua rau cov neeg tsim khoom siv los txhim kho MOSFET cov txiaj ntsig, ua kom lub sijhawm mus rau kev ua lag luam sai dua, thiab xa cov kev daws teeb meem sib tw ntau dua thoob plaws tsheb, lub zog rov ua dua tshiab, kev lag luam, thiab lwm yam kev siv loj hlob, Wolfspeed hais. Cov khoom lag luam thiab kev ua tau zoo no rau 200mm SiC kuj tseem tuaj yeem siv rau kev kawm tas mus li rau 150mm SiC cov khoom siv, lub tuam txhab ntxiv.
"Qhov kev nce qib no qhia txog Wolfspeed txoj kev cog lus ntev los thawb cov ciam teb ntawm cov khoom siv silicon carbide," Balkas hais. "Qhov kev tso tawm no qhia txog peb lub peev xwm los kwv yees cov kev xav tau ntawm cov neeg siv khoom, nthuav dav raws li kev thov, thiab xa cov ntaub ntawv uas ua rau yav tom ntej ntawm kev hloov pauv hluav taws xob zoo dua."
