Imikorere ihebuje ya Silicon Carbide Wafer Ubwato mu Gukura kwa Crystal

Inzira yo gukura ya Crystal iri mu mutima wo guhimba semiconductor, aho umusaruro wa waferi wo mu rwego rwo hejuru ari ngombwa.Ikintu cyingenzi muriyi nzira nisilicon karbide (SiC) ubwato bwa wafer.Ubwato bwa WaC bwamenyekanye cyane mu nganda kubera imikorere idasanzwe no kwizerwa.Muri iyi ngingo, tuzasesengura ibiranga bidasanzwe byaUbwato bwa SiCn'uruhare rwabo mu koroshya imikurire ya kirisiti mu gukora semiconductor.

Ubwato bwa SiCByashizweho muburyo bwo gufata no gutwara semiconductor wafer mugihe cyicyiciro gitandukanye cyo gukura kwa kristu.Nibikoresho, karibide ya silicon itanga ihuza ryihariye ryimitungo yifuzwa bigatuma ihitamo neza kubwato bwa wafer.Mbere na mbere ni imbaraga zidasanzwe zubukanishi hamwe nubushyuhe bwo hejuru.SiC ifite ubukana buhebuje no gukomera, ikabasha kwihanganira ibihe bikabije byahuye nabyo mugihe cyo gukura kwa kristu.

Inyungu imwe yingenzi yaUbwato bwa SiCni uburyo budasanzwe bwo gutwara ibintu.Gukwirakwiza ubushyuhe ni ikintu gikomeye mu mikurire ya kristu, kuko bigira ingaruka ku bushyuhe bw’ubushyuhe kandi bikarinda guhagarika ubushyuhe kuri wafer.Ubushyuhe bwo hejuru bwa SiC bworohereza ihererekanyabubasha neza, bikwirakwiza ubushyuhe buri gihe muri wafer.Ibi biranga ingirakamaro cyane mubikorwa nko gukura kwa epitaxial, aho kugenzura neza ubushyuhe ni ngombwa kugirango umuntu agere kuri firime imwe.

Byongeye kandi,Ubwato bwa SiCerekana ubudahangarwa bwimiti.Zirwanya ubwoko butandukanye bwimiti yangiza na gaze bikoreshwa mugukora semiconductor.Iyi miti ihamye iremeza koUbwato bwa SiCkomeza ubunyangamugayo n'imikorere mugihe kirekire cyo guhura nibidukikije bikaze.kurwanya ibitero byimiti birinda kwanduza no kwangirika kwibintu, kurinda ubwiza bwa waferi ikura.

Ubwinshi bwimiterere yubwato bwa SiC nubundi buryo bugaragara.Byashizweho kugirango bigumane imiterere yabyo ndetse no mubushyuhe bwo hejuru, byemeza neza ko wafer ihagaze mugihe cyo gukura kwa kirisiti.Ihungabana rinini rigabanya ihinduka iryo ariryo ryose cyangwa ubwato bwubwato, bushobora gutuma habaho kudahuza cyangwa gukura kudahuje ibice.Iyi myanya isobanutse ningirakamaro kugirango ugere ku cyifuzo cya kristu yerekana icyerekezo hamwe nuburinganire bwibikoresho biva mu gice cya kabiri.

Ubwato bwa WaC butanga kandi ibikoresho byiza byamashanyarazi.Carbide ya Silicon nigikoresho cya semiconductor ubwayo, irangwa na bande yagutse hamwe na voltage yo kumeneka cyane.Ibikoresho byamashanyarazi bya SiC byemeza ko amashanyarazi adashobora kumeneka no kwivanga mugihe cyo gukura kwa kirisiti.Ibi ni ingenzi cyane mugihe ukura ibikoresho bifite ingufu nyinshi cyangwa gukorana nibikoresho bya elegitoroniki byoroshye, kuko bifasha kugumana ubusugire bwibikoresho bya semiconductor bikorerwa.

Byongeye kandi, ubwato bwa SiC wafer buzwiho kuramba no kongera gukoreshwa.Bafite igihe kirekire cyo gukora, hamwe nubushobozi bwo kwihanganira ibihe byinshi byo gukura kwa kirisiti nta kwangirika gukomeye.Uku kuramba bisobanurwa neza-bigabanya kandi bigakenera gusimburwa kenshi.Kongera gukoresha ubwato bwa SiC wafer ntabwo bugira uruhare mubikorwa byinganda zirambye gusa ahubwo binatanga imikorere ihamye kandi yizewe mubikorwa byo gukura kwa kristu.

Mu gusoza, ubwato bwa waC bwa SiC bwabaye ikintu cyingenzi mu mikurire ya kirisiti yo gukora igice cya kabiri.Imbaraga zidasanzwe zubukanishi, ubushyuhe bwo hejuru bwubushyuhe, ubushyuhe bwumuriro, ubudahangarwa bwimiti, ituze ryimiterere, hamwe namashanyarazi bituma bifuzwa cyane mukworohereza inzira yo gukura.Ubwato bwa wafer bwa SiC butuma ubushyuhe bukwirakwizwa, birinda kwanduza, kandi bigafasha guhagarara neza kwa wafer, amaherezo biganisha ku gukora ibikoresho byujuje ubuziranenge bwo mu rwego rwo hejuru.Mugihe icyifuzo cyibikoresho bigezweho bya semiconductor bikomeje kwiyongera, akamaro k’ubwato bwa SiC wafer mu kugera ku mikurire myiza ya kirisiti ntishobora kuvugwa.
