Wafer ikozwe muri silicon nziza (Si). Mubisanzwe bigabanijwemo ibice 6, santimetero 8, na santimetero 12, wafer ikorwa hashingiwe kuri iyi wafer. Wafer ya silicon yateguwe kuva igice kinini cyogukora neza binyuze mubikorwa nko gukurura kristu no gukata byitwa wafers becaKoresha ni uruziga. Ibikoresho bitandukanye byumuzunguruko birashobora gutunganyirizwa kuri silicon wafers kugirango bibe ibicuruzwa bifite amashanyarazi yihariye. imikorere yumuzunguruko ikora. Wafers inyura murukurikirane rwibikorwa bya semiconductor kugirango ikore ibintu bito cyane byumuzunguruko, hanyuma bigacibwa, bipakirwa, kandi bipimwa muri chip, bikoreshwa cyane mubikoresho bya elegitoroniki bitandukanye. Ibikoresho bya Wafer byahuye nimyaka irenga 60 yubwihindurize niterambere ryinganda, bikora ibintu byinganda byiganjemo silikoni kandi byunganirwa nibikoresho bishya bya semiconductor.
80% bya terefone zigendanwa na mudasobwa ku isi bikorerwa mu Bushinwa. Ubushinwa bushingiye ku bicuruzwa bitumizwa mu mahanga 95% by’ibicuruzwa bikora neza, bityo Ubushinwa bukoresha miliyari 220 z'amadolari ya Amerika buri mwaka mu gutumiza ibicuruzwa biva mu mahanga, bikubye kabiri Ubushinwa butumiza peteroli buri mwaka. Ibikoresho byose nibikoresho bijyanye nimashini zifotora hamwe nogukora chip nabyo birahagaritswe, nka wafer, ibyuma byera cyane, imashini zangiza, nibindi.
Uyu munsi turaza kuvuga muri make ihame rya UV yohanagura imashini ya wafer. Mugihe wandika amakuru, birakenewe gushiramo amafaranga mumarembo areremba ukoresheje voltage ndende VPP kumuryango, nkuko bigaragara mumashusho hepfo. Kubera ko inshinge zatewe zidafite imbaraga zo kwinjira mu rukuta rwingufu za firime ya silicon oxyde, irashobora gukomeza uko ibintu bimeze, bityo rero tugomba guha amafaranga imbaraga runaka! Nigihe urumuri ultraviolet rukenewe.
Iyo irembo rireremba ryakiriye imirasire ya ultraviolet, electron mu irembo rireremba zakira ingufu za ultraviolet yumucyo, kandi electron ziba electron zishyushye zifite imbaraga zo kwinjira murukuta rwingufu za firime ya silicon. Nkuko bigaragara kuri iki gishushanyo, electron zishyushye zinjira muri firime ya silicon oxyde, itemba kuri substrate n irembo, hanyuma igasubira muri leta yahanaguwe. Igikorwa cyo gusiba gishobora gukorwa gusa no kwakira imirasire ya ultraviolet, kandi ntishobora guhanagurwa hakoreshejwe ikoranabuhanga. Muyandi magambo, umubare wa bits urashobora guhinduka gusa kuva "1" ukagera kuri "0", no muburyo bunyuranye. Nta bundi buryo usibye gusiba ibiri muri chip.
Turabizi ko imbaraga zumucyo zingana nuburebure bwumucyo. Kugirango electron zibe electron zishyushye bityo zikagira imbaraga zo kwinjira muri firime ya oxyde, imirasire yumucyo hamwe nuburebure buke bwumuraba, ni ukuvuga imirasire ya ultraviolet, irakenewe cyane. Kubera ko igihe cyo gusiba giterwa numubare wa fotone, igihe cyo gusiba ntigishobora kugabanywa no muburebure buke. Mubisanzwe, gusiba bitangira iyo uburebure bwa 4000A (400nm). Ahanini igera kuri kwiyuzuza hafi 3000A. Munsi ya 3000A, nubwo uburebure bwumurongo ari bugufi, ntabwo bizagira ingaruka mugihe cyo gusiba.
Igipimo cyo gusiba UV muri rusange ni ukwemera imirasire ya ultraviolet ifite uburebure bwuzuye bwa 253.7nm hamwe nuburemere bwa 00016000 μ W / cm². Igikorwa cyo gusiba kirashobora kurangizwa nigihe cyo kwerekana kuva kuminota 30 kugeza kumasaha 3.
