Iyini I-Epi Carrier?

Ukuhlola Indima Yayo Ebalulekile Ekucubunguleni I-Epitaxial Wafer

Ukuqonda Ukubaluleka Kwezinkampani Ze-Epi Ekwenziweni Okuthuthukisiwe Kwe-Semiconductor

Embonini ye-semiconductor, ukukhiqizwa kwekhwalithi ephezulu ye-epitaxial (epi)izinkwa eziwucwecwekuyisinyathelo esibalulekile emishinini yokukhiqiza efana nama-transistors, ama-diode, nezinye izakhi zikagesi. Okubalulekile kule nqubo yi-I-epi carrier, ithuluzi elikhethekile elidizayinelwe ukubamba ama-wafers ngokuphephile ngesikhathi sokubekwa kwe-epitaxial. Kodwa iyini ngempela i-epi carrier, futhi kungani ibaluleke kangaka ekwenzeni i-semiconductor?

Ukukhula kwe-Epitaxial: Inqubo Eyinhloko Ekwenziweni Kwe-Semiconductor

Ukukhula kwe-Epitaxial, noma i-epitaxy, ibhekisela ohlelweni lokubeka ungqimba oluncane lwe-crystalline material ku-wafer ye-semiconductor. Lolu ngqimba, olwaziwa ngokuthi ungqimba lwe-epitaxial, lunomumo wekristalu ofanayo njenge-substrate engaphansi futhi lusetshenziselwa ukuthuthukisa izici zikagesi ze-wafer. I-Epitaxy ibalulekile ekudaleni amadivaysi asebenza kahle kakhulu adinga ukulawula okunembayo phezu kokwakheka nokwakheka kwezinto.

Ukuze kuzuzwe ikhwalithi oyifunayo kanye nokufana kungqimba lwe-epitaxial, ama-wafers kufanele abanjwe ngokunemba nokuzinza ngesikhathi senqubo yokubeka. Yilapho i-I-epi carrieruyadlala.

Iqhaza lika-I-Epi Carrier

An I-epi carrieriwukulungisa okuklanywe ngokukhethekile okubamba ama-wafers ngesikhathi senqubo yokubeka i-epitaxial. Ngokuvamile yenziwe ngezinto ezihlanzeke kakhulu ezingamelana namazinga okushisa aphezulu kanye nezindawo ezisebenzayo ezihilelekile ku-epitaxy. Idizayini yenkampani yenethiwekhi iqinisekisa ukuthi ama-wafer abekwe ngokuvikelekile futhi avezwe ngokulinganayo ezintweni zokubeka, okuholela kungqimba olufana lwe-epitaxial kuyo yonke indawo eyi-wafer.

Omunye wemisebenzi eyinhloko ye-epi carrier ukugcina i-kwe-waferukuzinza nokuqondanisa kuyo yonke inqubo yokubeka. Noma yikuphi ukunyakaza noma ukungahambi kahle kungaholela ekushiyekeni kungqimba lwe-epitaxial, okungaba nomthelela omkhulu ekusebenzeni kwedivayisi yokugcina ye-semiconductor. Umthwali kufanele futhi avimbele ukungcola futhi aqinisekise ukuthi ama-wafers ahlala engenazo izinhlayiya noma ukungcola ngesikhathi sokucubungula.

KunganiI-Epi CarriersZibalulekile Ekwenziweni Kwe-Semiconductor

Ikhwalithi yesendlalelo se-epitaxial ithinta ngqo ukusebenza kwamadivayisi we-semiconductor. Kanjalo, indima yomthwali we-epi ibalulekile ekuzuzeni amazinga aphezulu adingekayo embonini. Ngokuhlinzeka ngendawo ezinzile nelawulwayo yokucutshungulwa kwe-wafer, isithwali se-epi siqinisekisa ukuthi ungqimba lwe-epitaxial lufakwa ngendlela efanayo futhi ngaphandle kwamaphutha.

Abathwali be-Epi nabo babalulekile ekusekeleni ukuqina kokukhiqizwa kwe-semiconductor. Njengoba ijometri yedivayisi iqhubeka nokuncipha futhi isidingo sokusebenza okuphezulu sikhula, isidingo sezinqubo ze-epitaxial ezinembayo nezithembekile siba bucayi nakakhulu. Izithwali ze-epi zekhwalithi ephezulu zisiza abakhiqizi ukuthi bahlangabezane nalezi zidingo ngokunika amandla imiphumela engaguquki futhi ekhiqizeka kabusha, njengoba ukukhiqizwa kukhuphuka.

Isiphetho

Kafushane, inkampani ye-epi iyithuluzi elibalulekile ohlelweni lokukhiqiza lwe-semiconductor, ikakhulukazi ekukhiqizeni ama-wafers e-epitaxial. Iqhaza layo ekuqinisekiseni ukuzinza kwe-wafer, ukuqondanisa, nokulawula ukungcoliswa kubalulekile ukuze kuzuzwe izendlalelo zekhwalithi ephezulu ze-epitaxial ezidingekayo kumadivayisi athuthukile we-semiconductor. Njengoba imboni iqhubeka nokuphusha imingcele yobuchwepheshe, ukubaluleka kwabathwali be-epi abanokwethenjelwa nabasebenza kahle kuzokwanda kuphela, okubenza babe yingxenye ebalulekile ekuphishekeleni ukwenza kahle ekwenziweni kwe-semiconductor.

Kulabo abasembonini ye-semiconductor abafuna ukuthuthukisa izinqubo zabo ze-epitaxial, ukuqonda kanye nokutshala imali kubathwali be-epi bekhwalithi ephezulu kuyisinyathelo esibalulekile sokuthola imiphumela engcono kanye nokugcina umkhawulo wokuncintisana emakethe.
