I roto i ngā ahumahi semiconductor me te optoelectronics, ko teKawe SiC (Silicon Carbide)He mahi nui tā te wafer ki te tukatuka i ngā wafer tino angiangi. Ka whakatakotoria te wafer ki runga i te kawe SiC porous, ā, ka mau mā te momi korehau, ka taea ai te whakauru pai ki ngā mahi matua pēnei i:
● Te whakawāki: Te paninga i tētahi paparanga tiaki.
● Te Whakaiti: Te whakaiti i te matotoru o te papa.
● Te tango ware pi: Te tango i te paparanga tiaki.
● Te horoi: Te whakarite kia ma te mata.
● Te Tapahi (Tapahi): Te wehe i te angaanga kia takitahi.
Ka whakangawaritia e ngā kaikawe SiC ēnei mahi uaua, ka whai wāhi nui ki te whai huatanga me te kounga o tō raina whakaputa.
Ngā Āhuatanga Matua Me Whai e tō Kaikawe SiC
I te wā e whiriwhiri ana i tētahi kaikawe SiC, he mea nui ētahi āhuatanga hei whakarite i te mahi tino pai me te whakanui ake i tō hokinga mai o te haumi. E mārama ana mātou ko ngā kaimahi hangarau me ngā kaiwhakahaere hoko e whakatairanga ana i ngā āhuatanga motuhake e pā tika ana ki te pai o te tukanga me te kounga o te hua.
1. Te Arahi Wera Tino Pai
He tino pai te kawe wera o tētahi kaikawe SiC pai rawa atu. He mea nui tēnei āhuatanga mō:
●Te Whakapoto i te Wā Whakawātea me te Tango Waewae: Mā te whakawhiti wera whai hua ka tere ake ēnei tukanga wera, ka tino whakaiti i te wā huringa whānui.
●Te Whakapai Ake i te Tere Whakaputa: Ko te tukatuka tere ake ka hua ake he nui ake te rere o ngā wafers.
●Te Whakanui Ake i te Whai Hua o te Whakaputa: Mā te whakahaere wera pai rawa atu ka whai wāhi atu ki te rere o te whakaputanga kia māmā ake, kia whai hua ake hoki.
2. Te Rahi o ngā Pore Iti me te Tohatoha ōrite:
Ko te whai huatanga o te momi korehau e whakawhirinaki nui ana ki te hanganga o ngā pūwero o te kaikawe. Ko ngā āhuatanga o te kaikawe SiC tino pai:
●He iti ngā pūwero: Ka ārai i te kino o ngā angiangi ngawari, ā, ka whakarite kia ōrite te tohatoha o te korehau.
●Ngā Pūwero Kua Tohatoha Pai: Ka oati i te mimiti ōrite puta noa i ngā rohe katoa o te anga katoa, ka ārai i te piko, te piko, te neke rānei i te wā e tukatuka ana.
3. Ātete Waikawa me te Kawakore Tino Pai:
I te mea he nui ngā matū e whakamahia ana i roto i te tukatuka wafer, me ātete tō kaikawe SiC ki ngā taiao waikura. Ko te ātete nui ki te waikawa me te kawakore ka whakarite kia:
●Te Pakari me te Roa o te Ora: Ka mau tonu te pumau o te hanganga me te mahi a te kaikawe mō ngā wā roa.
●Te Whakaiti i te Mōrearea o te Parahanga: Ka whakaitihia te tūponotanga o te turuturu o ngā paru ki runga i te papa whakarewa mā te ātete ki te pirau matū.
