Isikebhe se-Quartz sokusabalalisa i-Wafer Processing

I-Quartz Boat yethu iyisithwali se-silica wafer esixubene esiphezulu esiklanyelwe izinqubo zokusabalalisa ekukhiqizeni i-semiconductor. Idizayinelwe ukumelana nezinga lokushisa eliphezulu nezimo zenqubo ezinolaka, ihlinzeka ngosekelo lwemishini oluzinzile kuyilapho inciphisa ukungcoliswa, iqinisekisa ukusebenza okuhle ngesikhathi sokucutshungulwa kwe-wafer.

Thuthukisa I-Diffusion Uniformity ekucubunguleni i-Wafer

Ukuzuza ukusatshalaliswa kwe-dopant okufanayo kuwo wonke ama-wafers ohlelweni lokusabalalisa kubalulekile ekusebenzeni kwedivayisi ye-semiconductor kanye nesivuno. Ukufana kokusabalalisa kuncike ekulawuleni izinga lokushisa, amandla okugeleza kwegesi, ukuma kwe-wafer, nokuhambisana kwezinto. Ngezansi ukuhlaziywa kwezobuchwepheshe okunemininingwane yezinto ezibalulekile nezisombululo:

1. Ukuphathwa Kwe-Thermal Okuthuthukisiwe

Inkinga: Ukusatshalaliswa kwezinga lokushisa elingalingani kuwo wonke amawafa noma ngaphakathi kweshubhu yesithando somlilo kudala amazinga okusabalalisa aguquguqukayo, okuholela kumehluko we-radial noma we-axial.

Isixazululo:

● Sebenzisa izikebhe zequartz ezinezikhala ezinembile ukuze unciphise ama-thermal gradients.

● Sebenzisa isilawuli sesithando sezoni eziningi ukuze ulungise kahle izinga lokushisa ngobude beshubhu lokusabalalisa.

● Kancane kancane amazinga okushisa anyukayo kanye nawehla ukuze kwehliswe ukushaqeka okushisayo kanye nezindawo ezishisayo zendawo.

2. Ukugeleza Kwegesi Okulawulwayo kanye Nokulethwa Kwe-Dopant

Inkinga: Ukugeleza kwegesi okungajwayelekile kuholela ekugxilweni okuhlukahlukene kwe-dopant ezindaweni eziyisinkwa esiyisicwecwana, okubangela ukujula okungahambisani.

Isixazululo:

● Dizayina izikhala zezikebhe kanye nesikhala esilucwecwana ukuze ukhuthaze ukugeleza kwegesi ye-laminar eduze kwewafa ngayinye.

● Lungisa indawo yokuphuma kwegesi kanye namazinga okugeleza ukuze kuqedwe izindawo ezifile kanye nesiyaluyalu.

● Hlanza njalo izikebhe ukuze uvimbele ukuchithwa kwegesi okungavimba imigudu yegesi.

3. Ukuma kwe-wafer kanye nokucushwa komthwalo

Inkinga: Ukupakishwa kwe-wafer okungalungile noma umumo kungabangela imiphumela yethunzi kanye nokuchayeka okungajwayelekile kumagesi asakazwayo.

Isixazululo:

● Gcina isikhala se-slot esingashintshi ngokusekelwe kusayizi we-wafer nobubanzi besithando somlilo.

● Gwema ukulayisha ngokweqile isikebhe; gcina amabanga alungile we-wafer-to-wafer.

● Jikelezisa noma uphenye amawafa ezinqubweni ezinamaqoqo amaningi uma kunesidingo ukuze ubhalansise ukuchayeka.

Ekucutshungulweni kwe-wafer esakazwayo, Izikebhe ze-Quartz zidlala indima enemisebenzi eminingi--kusuka ekusekelweni kwemishini okunembayo, ukuphathwa kwe-thermal okufanayo, ukuchayeka kwegesi okulawulwayo, ukuncishiswa kokungcoliswa, ukuya ekuvumela ukucutshungulwa kweqoqo eliphezulu. Ukukhetha okufanele kwesikebhe, ukunakekelwa, nokuqondanisa kubalulekile ukuze kuqinisekiswe amaphrofayili okusabalalisa angaguquki, isivuno esikhulu, nokuthembeka kwedivayisi. I-Semixlab iyakwamukela ukubonisana kwakho ngesidingo somkhiqizo owenziwe ngokwezifiso.

Izicelo Zezikebhe Ze-Quartz Ezinqubweni Zokusabalalisa

Izikebhe ze-Quartz zingaphezu kwezibambi ezilucwecwe ezinqubweni zokusabalalisa; ukwakheka kwawo kanye nezakhiwo zawo ezibonakalayo kuthinta ngqo ikhwalithi ye-wafer, ukufana kwe-dopant, kanye nesivuno. Ngezansi incazelo enemininingwane yezicelo zabo ezibalulekile:

1. Ukusekelwa Kwemishini kanye Nokuma Kwe-wafer Okunembile

Izikebhe ze-Quartz zinikeza ukwesekwa okuzinzile okuqondile kwama-wafer amaningi, ukuvimbela ukugoba, ukushelela, noma ukungqubuzana phakathi nemijikelezo yokushisa okuphezulu.

I-Slot Design Nokuqondanisa: Imbobo ngayinye yakhelwe ukugcina isikhala esingaguquguquki se-wafer-to-wafer, okubalulekile ekucutshungulweni kweqoqo. Isikhala esilungile siqinisekisa:

2. Ukuphathwa Okushisayo

Ukunwebeka okuphansi kokushisa kwe-quartz kanye nokuzinza okuphezulu kokushisa kuyivumela ukuthi igcine ubuqotho besakhiwo emazingeni okushisa asukela ku-800°C kuya ku-1,200°C.

Ukusabalalisa Ukushisa Okufanayo: Ijiyomethri yesikebhe kanye nokumelana nokushisa okuphezulu kwe-quartz kusiza ukugcina izinga lokushisa le-wafer phezu kwayo yonke inqwaba, okuthinta ngokuqondile amaphrofayili e-dopant diffusion.

3. Ukusiza Ukugeleza Kwegesi kanye Nokusabalalisa I-Dopant

Idizayini yezikebhe ze-quartz iqinisekisa ukugeleza kwe-laminar yamagesi enqubo azungeze isicwecwana ngasinye, kuvimbele izindawo ezifile kanye nokungalingani kokuhlushwa kwendawo.

Isikhala esifanele sivumela ngisho ukuchayeka kumagesi e-oxidizing noma ama-dopant, okuqinisekisa ukujula kwe-junction efanayo kanye nezici zikagesi ezingaguquki.

4. Ukuvimbela Ukungcola

I-quartz ayifaki amakhemikhali emazingeni okushisa aphezulu, inciphisa ukungcoliswa kwensimbi kanye nokukhiqizwa kwezinhlayiya, okuyizici ezivamile zokunciphisa isivuno ezinqubweni zokusabalalisa.

Ubuqotho Bokuphezulu: Izindawo ezibushelelezi nezingenasici zinciphisa ukuchitheka kwezinhlayiyana. Ukumboza noma ukupholisha kungase kusetshenziswe ukuphila okunwetshiwe ezinqubweni ezinolaka.

5. Iqoqo Lokusebenza kanye Nokuphumelela Kwenqubo

Izikebhe ze-quartz zenzelwe ukukhulisa inani lama-wafers ngeqoqo ngalinye ngaphandle kokuphazamisa ukufana okushisayo noma ukuhamba kwegesi.Lokhu kuvumela ukuphuma okuphezulu, okubalulekile ekukhiqizeni i-semiconductor yevolumu ephezulu.
