Mīhini Tika
I muri i te whakahinuhinu, ka mīhinihia ngā paepae kia tutuki ai ngā ātete āhua kikī, te āhua maeneene o te mata, me te papatahi. Ka taea te whakamahi i ngā maimoatanga mata pēnei i te miro, te huri, me te whakakanapa i runga i ngā hiahia o te kiritaki.
Ngā tono noa
E whakamahia ana ngā paepae uku silicon carbide i roto i te tini o ngā ahumahi nā te mea he maha ngā whakamahinga me te pakari. Ko ngā whakamahinga noa ko:
-
Ahumahi Ārahi-Haumaru
Ka whakamahia ngā paepae SiC hei kaikawe i ngā tukanga whakamahana, te horapa, te waikura, te epitaxy, me te whakatō. Mā te pumau ka rite te tohatoha pāmahana me te iti o te poke. -
Ahumahi Whakaahua-pūngao (PV)
I roto i te hanga pūtau rā, ka tautokohia e ngā paepae SiC ngā poro silicon, ngā anga rānei i ngā wā horapa me te sintering pāmahana teitei. -
Te Whakarewa Paura me te Uku
Whakamahia hei tautoko i ngā wāhanga i te wā e whakawerahia ana ngā paura whakarewa, ngā uku, me ngā rauemi hiato. -
Ngā Paewhiri Karāhe me ngā Paewhiri Whakaaturanga
Ka whakamahia hei paepae oumu, hei papa rānei mō te hanga mōhiti motuhake, papa LCD, me ētahi atu wāhanga whatu. -
Te Tukatuka Matū me ngā Oumu Wera
Hei kawe ātete-waikura i roto i ngā tauhohenga matū, hei paepae tautoko wera rānei i roto i ngā oumu korehau me ngā oumu hauhautanga e whakahaerehia ana.
