Kei roto i te taonga te wafer FZ CZ Si 12inihi Silicon wafer Prime or Test

Ngā Waferi Orohia

He angaanga silicon kua orohia motuhake i ngā taha e rua kia rite ki te mata whakaata. Ko ngā āhuatanga pai rawa atu pēnei i te parakore me te papatahi e tautuhi ana i ngā āhuatanga pai rawa atu o tēnei angaanga.

Ngā Waferi Silicon Kāore i Tāpirihia

E mōhiotia ana hoki ēnei ko ngā papa silicon ā-roto. He momo tioata parakore tēnei haurua-whakakotahi o te silicon, kāore he tāpiringa i roto i te papa, nō reira he haurua-whakakotahi tino pai, tino tika hoki.

Ngā Waferi Silicon kua Tāpirihia

Ko te momo-N me te momo-P ngā momo e rua o ngā anga silicon kua tāpirihia.

Kei roto i ngā papa silicon kua pania ki te momo-N te arsenic, te phosphorus rānei. He whānuitia te whakamahinga i roto i te hanga i ngā taputapu CMOS matatau.

He anga silicon momo-P kua pania ki te boron. Ko te nuinga o te wā, ka whakamahia hei hanga ara iahiko tānga, hei hanga whakaahua rānei.

Ngā Wafer Epitaxial

Ko ngā papa epitaxial he papa tuku iho e whakamahia ana hei whiwhi i te āhua o te mata. Kei te wātea ngā papa epitaxial i roto i ngā papa matotoru me ngā papa angiangi.

Ka whakamahia hoki ngā angaanga epitaxial maha-paparanga me ngā angaanga epitaxial matotoru hei whakahaere i te whakapaunga pūngao me te whakahaere mana o ngā taputapu.

E whakamahia whānuitia ana ngā angiangi epitaxial i roto i ngā taputapu MOS pai ake.

Ngā Wafer SOI

Ka whakamahia ēnei paparanga hei ārai hiko i ngā paparanga angiangi o te silicon tioata kotahi mai i te paparanga silicon katoa. He mea noa te whakamahi i ngā paparanga SOI i roto i ngā mahi photonics silicon me ngā tono RF mahi teitei. Ka whakamahia hoki ngā paparanga SOI hei whakaiti i te kaha o te taputapu pirinoa i roto i ngā taputapu hiko moroiti, e āwhina ana ki te whakapai ake i te mahi.

He aha te uaua o te hanga i te wafer?

He tino uaua te tapatapahi i ngā papa silicon 12-inihi te roa, ā, he pakari te hanga. Ahakoa he mārō te silicon, he pakarukaru anō hoki. Ka hangaia ngā wāhi taratara i te mea ka whati ngā taha papa kua tāraihia. Ka whakamahia ngā kōpae taimana hei whakangawari i ngā taha papa me te tango i ngā pakaru. I muri i te tapahi, ka pakaru ngāwari ngā papa nā te mea he koi ngā taha. Ka hangaia ngā taha papa kia kore ai e pakaru ngā taha koi, ā, ka whakaitihia te tūponotanga o te paheke. Nā te mahi hanga taha, ka whakatikatikaina te diameter o te papa, ka porowhita te papa (i muri i te tapatapahi, ka porowhita te papa kua tapahia), ā, ka hangaia, ka rahihia rānei ngā koki, ngā papa rānei e anga ana.
