Kua pānuitia e Wolfspeed Inc o Durham, NC, USA — e hanga ana i ngā rauemi silicon carbide (SiC) me ngā taputapu hiko semiconductor — te whakarewatanga arumoni o āna hua rauemi 200mm SiC, he tohu tēnei i roto i tana kaupapa ki te whakatere i te whakawhiti a te umanga mai i te silicon ki te silicon carbide. Whai muri i te tukunga tuatahi o te 200mm SiC ki ētahi kiritaki, e kī ana te kamupene nā te urupare pai me ngā painga i tika ai te tukunga arumoni ki te mākete.
Kei te tuku hoki a Wolfspeed i te epitaxy SiC 200mm hei whakamātautau tonu, ina honoa ki ana wafers tahanga 200mm, ka tukuna he mea e kiia ana he tauine nui me te kounga pai ake, ka taea ai te whakatipuranga hou o ngā taputapu hiko mahi-teitei.
"Ehara i te mea he whānui noa iho ngā angaanga SiC 200mm a Wolfspeed – engari he auahatanga rauemi e whakamana ana i ā mātou kiritaki ki te whakateretere i ā rātou mahere mahi taputapu me te māia," te kī a Tākuta Cengiz Balkas, te tumuaki pakihi. "Mā te tuku kounga i te tauine, kei te āhei a Wolfspeed i ngā kaihanga hikohiko mana ki te whakatutuki i te hiahia e tipu haere ana mō ngā otinga silicon carbide he pai ake te mahi, he pai ake te whai hua."
Ko ngā whakatakotoranga tauwhāiti kua whakapaitia o ngā anga tahanga SiC 200mm i te matotoru 350µm me te mea e kīia ana he pai ake, he ārahi-a-umanga te doping me te ōritetanga matotoru o te epitaxy 200mm ka taea e ngā kaihanga taputapu te whakapai ake i ngā hua MOSFET, te whakateretere i te wā-ki-te-mākete, me te tuku otinga whakataetae ake puta noa i ngā tono motuka, pūngao whakahou, ahumahi, me ētahi atu tono tipu nui, e ai ki a Wolfspeed. Ka taea hoki te whakamahi i ēnei whanaketanga hua me te mahi mō te 200mm SiC ki ngā ako tonu mō ngā hua rauemi SiC 150mm, e ai ki te kamupene.
"E whakaata ana tēnei whanaketanga i te whakapau kaha roa a Wolfspeed ki te pana i ngā rohe o te hangarau rauemi silicon carbide," te kī a Balkas. "E whakaatu ana tēnei whakarewatanga i tō mātou kaha ki te matapae i ngā hiahia o te kiritaki, te tauine i runga i te tono, me te tuku i te turanga rauemi e taea ai te heke mai o te huringa hiko whai hua ake."
