FZ CZ Si wafer kwisitokhwe 12inch Silicon wafer Prime okanye Test

Inkcazelo emfutshane:

I-12 intshi ye-silicon wafer yimathiriyeli encinci ye-semiconductor esetyenziswa kwizicelo ze-elektroniki kunye neesekethe ezidibeneyo. Iziqwenga ze-silicon zizinto ezibaluleke kakhulu kwiimveliso zombane eziqhelekileyo ezinjengeekhompyuter, iiTV kunye neeselfowuni. Kukho iintlobo ezahlukeneyo ze-wafers kwaye nganye ineempawu zayo ezithile. Ukuqonda eyona nto ifanelekileyo ye-silicon wafer kwiprojekthi ethile, kufuneka siqonde iintlobo ezahlukeneyo zeewafers kunye nokufaneleka kwazo.

Ukwazisa ngebhokisi ye-wafer

IiWafers ezikhazimlisiweyo

Ii-Silicon wafers ezigudiswe ngokukodwa kumacala omabini ukufumana indawo yesipili. Iimpawu eziphezulu ezinjengobunyulu kunye nokuthambeka zichaza ezona mpawu zibalaseleyo zesi siqwengana sisonke.

IiWafers zeSilicon ezingagqitywanga

Zikwabizwa ngokuba zii-intrinsic silicon wafers. Le semiconductor luhlobo olusulungekileyo lwekristale yesilicon ngaphandle kobukho bayo nayiphi na i-dopant kuyo yonke i-wafer, ngaloo ndlela iyenza ibe yeyona semiconductor efanelekileyo negqibeleleyo.

IiWafers zeSilicon eziDoped

Udidi lwe-N kunye nohlobo lwe-P luhlobo ezimbini ze-silicone wafers.

I-N-type doped silicon wafers iqulethe i-arsenic okanye i-phosphorus. Isetyenziswa ngokubanzi ekwenzeni izixhobo eziphambili zeCMOS.

I-Boron doped P-type wafers silicon. Ubukhulu becala, isetyenziselwa ukwenza iisekethe eziprintiweyo okanye iphotolithography.

Epitaxial Wafers

I-Epitaxial wafers ziwafers eziqhelekileyo ezisetyenziselwa ukufumana imfezeko yomphezulu. Ii-wafers ze-Epitaxial ziyafumaneka kwii-wafers ezityebileyo nezibhityileyo.

I-Multilayer epitaxial wafers kunye ne-epitaxial wafers ezishinyeneyo zikwasetyenziswa ukulawula ukusetyenziswa kwamandla kunye nolawulo lwamandla ezixhobo.

Ii-wafers ze-epitaxial ezinqabileyo ziqhele ukusetyenziswa kwizixhobo eziphezulu ze-MOS.

Ii-wafers ze-SOI

Ezi ziqwenga zisetyenziselwa ukugquma ngombane umaleko ocolekileyo wesilicon enye yekristale ukusuka kuyo yonke i-silicon wafer. Ii-wafers ze-SOI ziqhele ukusetyenziswa kwi-silicon photonics kunye nosetyenziso oluphezulu lweRF. Ii-wafers ze-SOI zikwasetyenziselwa ukunciphisa i-parasitic device capacitance kwizixhobo ze-microelectronic, ezinceda ukuphucula ukusebenza.

Kutheni kunzima ukwenza iwafer?

Ii-intshi ezili-12 ze-silicon wafers zinzima kakhulu ukuziqhekeza ngokwemveliso. Nangona i-silicon inzima, nayo i-brittle. Iindawo ezirhabaxa zidalwe njengoko imiphetho ye-wafer esarhiweyo ithanda ukuqhawuka. Iidiski zedayimani zisetyenziselwa ukugudisa imiphetho ye-wafer kwaye zisuse nawuphi na umonakalo. Emva kokusikwa, ama-wafers aphuka ngokulula kuba ngoku aneencam ezibukhali. I-Wafer edges yenziwe ngendlela yokuba i-fragile, i-edges ebukhali ikhutshwe kwaye ithuba lokukhupha liyancipha. Njengomphumo wokwenziwa komphetho wokusebenza, ububanzi be-wafer buhlengahlengiswa, i-wafer ijikelezwe (emva kokuqhawula, i-wafer enqunyiweyo i-oval), kunye neenotshi okanye iindiza eziqhelanisiweyo zenziwe okanye ubukhulu.
