I-wafer ye-FZ CZ Si ikwisitokhwe se-12inch Silicon wafer Prime okanye Test

I-wafer ye-FZ CZ Si ikwisitokhwe se-12inch Silicon wafer Umfanekiso oPhambili okanye oVavanyo

Inkcazo emfutshane:

I-wafer ye-silicon eyi-intshi ezili-12 sisixhobo esibhityileyo se-semiconductor esisetyenziswa kwizicelo ze-elektroniki kunye neesekethe ezidibeneyo. Ii-wafer ze-silicon zizinto ezibaluleke kakhulu kwiimveliso ze-elektroniki eziqhelekileyo ezifana neekhompyutha, iiTV kunye neefowuni eziphathwayo. Kukho iintlobo ezahlukeneyo zee-wafer kwaye nganye ineempawu zayo ezithile. Ukuze siqonde i-wafer ye-silicon efanelekileyo kwiprojekthi ethile, kufuneka siqonde iintlobo ezahlukeneyo zee-wafer kunye nokufaneleka kwazo.

Iimbonakalo

Yazisa ngebhokisi ye-wafer

Iiwafers ezikhazimlisiweyo

Iiwafer zesilicon ezikhazimliswe ngokukodwa kumacala omabini ukuze zenze umphezulu wesipili. Iimpawu eziphezulu ezifana nobunyulu kunye nokuthe tyaba zichaza iimpawu ezilungileyo zale wafer.

IiWafer zeSilicon ezingafakwanga

Zikwaziwa ngokuba zii-wafers ze-silicon zangaphakathi. Le semiconductor luhlobo olucocekileyo lwe-silicon olungenazo izinto ezibangela ukuba i-wafer ibe yi-semiconductor efanelekileyo negqibeleleyo.

IiWafers zeSilicon ezifakwe idosi

Uhlobo lwe-N kunye nohlobo lwe-P ziintlobo ezimbini zee-wafers ze-silicon ezixutyiweyo.

Ii-wafers ze-silicon ezifakwe i-doped yohlobo lwe-N ziqulethe i-arsenic okanye i-phosphorus. Zisetyenziswa kakhulu ekwenzeni izixhobo ze-CMOS eziphambili.

Iiwafers zesilicon ezifakwe iBoron doped P-type. Ngokuyintloko, zisetyenziselwa ukwenza iisekethe eziprintiweyo okanye iphotolithography.

IiWafers ze-Epitaxial

Ii-wafer ze-Epitaxial zii-wafer eziqhelekileyo ezisetyenziselwa ukufumana umgangatho oqinileyo. Ii-wafer ze-Epitaxial ziyafumaneka kwii-wafer eziqinileyo nezincinci.

Ii-wafers ze-epitaxial ezinee-layer ezininzi kunye nee-wafers ze-epitaxial eziqinileyo nazo zisetyenziselwa ukulawula ukusetyenziswa kwamandla kunye nolawulo lwamandla ezixhobo.

Ii-wafers ezincinci ze-epitaxial zisetyenziswa kakhulu kwizixhobo ze-MOS eziphezulu.

IiWafers zeSOI

Ezi wafers zisetyenziselwa ukufihla ngombane iileya ezincinci ze-silicon enye yekristale kwi-wafer yonke ye-silicon. Ii-wafers ze-SOI zisetyenziswa kakhulu kwi-silicon photonics kunye nezicelo ze-RF ezisebenzayo kakhulu. Ii-wafers ze-SOI zikwasetyenziselwa ukunciphisa amandla esixhobo esibangela iiparasite kwizixhobo ze-microelectronic, nto leyo enceda ukuphucula ukusebenza.

Kutheni ukwenza iiwafer kunzima?

Ii-wafer ze-silicon eziyi-12 intshi kunzima kakhulu ukuzisika ngokwemveliso. Nangona i-silicon iqinile, ikwabuthathaka. Iindawo ezirhabaxa zenziwa njengoko imiphetho ye-wafer esarded idla ngokuqhekeka. Iidiski zedayimani zisetyenziselwa ukuthambisa imiphetho ye-wafer nokususa nawuphi na umonakalo. Emva kokusika, ii-wafer ziyaphuka lula kuba ngoku zinemiphetho ebukhali. Imiphetho ye-wafer yenzelwe ngendlela yokuba imiphetho ebuthathaka nebukhali isuswe kwaye amathuba okutyibilika ancitshiswe. Ngenxa yokusebenza kokwenza umphetho, ububanzi be-wafer buyalungiswa, i-wafer iyajikeleziswa (emva kokusikwa, i-wafer esikiweyo i-oval), kwaye kwenziwa ii-notches okanye ii-planes ezijolise kuyo okanye ezinobukhulu.
