I-wafer ye-FZ CZ Si esitokweni i-12inch Silicon wafer Prime noma Test

I-wafer ye-FZ CZ Si esitokweni I-wafer ye-Silicon engu-12inch Prime noma Test Isithombe Esifakiwe

Incazelo emfushane:

I-wafer ye-silicon engamasentimitha angu-12 iyinto encane ye-semiconductor esetshenziswa ezinhlelweni ze-elekthronikhi kanye nasezisekelweni ezihlanganisiwe. Ama-wafer e-silicon ayizingxenye ezibaluleke kakhulu emikhiqizweni evamile ye-elekthronikhi efana namakhompyutha, ama-TV kanye namafoni eselula. Kunezinhlobo ezahlukene zama-wafer futhi ngalinye linezakhiwo zalo ezithile. Ukuze siqonde i-wafer ye-silicon efaneleke kakhulu yephrojekthi ethile, kufanele siqonde izinhlobo ezahlukene zama-wafer kanye nokufaneleka kwawo.

Ama-Wafers Apholishiwe

Ama-wafer e-silicon acwebezelisiwe ngokukhethekile kuzo zombili izinhlangothi ukuze athole ubuso obufana nesibuko. Izici ezinhle kakhulu njengokuhlanzeka nokuba yisicaba zichaza izici ezinhle kakhulu zale wafer.

Ama-Silicon Wafers Angafakwanga Idophi

Zaziwa nangokuthi ama-wafer e-silicon angaphakathi. Le semiconductor iwuhlobo lwe-silicon olucwebezelayo olungenawo umthelela kuyo yonke i-wafer, okwenza kube yi-semiconductor efanelekile nephelele.

Ama-Silicon Wafers Afakwe I-Doped

Uhlobo lwe-N kanye nohlobo lwe-P yizinhlobo ezimbili zama-wafer e-silicon afakwe i-doped.

Ama-wafer e-silicon afakwe uhlobo lwe-N aqukethe i-arsenic noma i-phosphorus. Asetshenziswa kabanzi ekwenziweni kwamadivayisi e-CMOS athuthukile.

Ama-wafer e-silicon enziwe nge-boron doped P-type. Ngokuvamile, asetshenziselwa ukwenza amasekethe aphrintiwe noma i-photolithography.

Ama-Wafer e-Epitaxial

Ama-wafer e-Epitaxial angama-wafer avamile asetshenziselwa ukuthola ubuqotho bomphezulu. Ama-wafer e-Epitaxial atholakala ngama-wafer amakhulu namancane.

Ama-wafer epitaxial anezingqimba eziningi kanye nama-wafer epitaxial aqinile nawo asetshenziswa ukulawula ukusetshenziswa kwamandla kanye nokulawulwa kwamandla kwamadivayisi.

Ama-wafer amancane epitaxial avame ukusetshenziswa ezinsimbini ze-MOS ezisezingeni eliphezulu.

Ama-SOI Wafers

Lawa ma-wafer asetshenziselwa ukuvikela ngogesi izendlalelo ezincane ze-silicon eyodwa yekristalu kusuka ku-wafer yonke ye-silicon. Ama-wafer e-SOI avame ukusetshenziswa kuma-photonics e-silicon kanye nezinhlelo zokusebenza ze-RF ezisebenza kahle kakhulu. Ama-wafer e-SOI asetshenziswa futhi ukunciphisa amandla edivayisi e-parasite kumadivayisi e-microelectronic, okusiza ukuthuthukisa ukusebenza.

Kungani ukwenziwa kwe-wafer kunzima?

Ama-wafer e-silicon angu-12 intshi kunzima kakhulu ukuwasika ngokwezinga lokukhiqiza. Nakuba i-silicon iqinile, futhi iyaphuka. Izindawo ezinzima zenziwa njengoba imiphetho ye-wafer esakiwe ivame ukuphuka. Ama-disc edayimane asetshenziselwa ukushelela imiphetho ye-wafer nokususa noma yimuphi umonakalo. Ngemva kokusika, ama-wafer aphuka kalula ngoba manje anemiphetho ebukhali. Imiphetho ye-wafer yaklanywa ngendlela yokuthi imiphetho ebuthakathaka, ebukhali isuswe futhi ithuba lokushelela lincishiswe. Ngenxa yokusebenza kokwakheka komphetho, ububanzi be-wafer buyalungiswa, i-wafer iyayindilinga (ngemuva kokusikwa, i-wafer esikiwe iyi-oval), futhi kwenziwa ama-notches noma izindiza eziqondisiwe noma ezinobukhulu.
