Jaantus Faahfaahsan

Guudmarka Muraayadda Quartz

Iyadoo si degdeg ah loo horumarinayo semiconductors-ka awoodda leh iyo aaladaha bandgap ballaaran, doomaha quartz-ka caadiga ah waxay la kulmaan xaddidaadyo sida isbeddelka heerkulka sare, wasakhowga walxaha daran, iyo cimriga adeegga gaaban. Doomaha wafer-ka SiC, oo leh xasillooni heer sare ah, wasakhowga hooseeya, iyo cimri dheer, ayaa si isa soo taraysa u beddelaya doomaha quartz waxayna noqonayaan doorashada la door bidayo ee wax soo saarka qalabka SiC.

Astaamaha Muhiimka ah

1. Faa'iidooyinka Maaddada

Waxaa laga sameeyay SiC saafi ah oo heer sare ahadkaansho sare iyo xoog.
Barta dhalaalaysa oo ka sarreysa 2700°C, aad uga sarreysa quartz, taasoo hubinaysa xasillooni muddo dheer ah oo ka jirta deegaannada aadka u daran.

2. Sifooyinka Kulaylka

Gudbinta kulaylka sare si loo helo wareejinta kulaylka degdega ah oo siman, yareynta cadaadiska wafer-ka.
Isugeynta ballaarinta kulaylka (CTE) waxay si dhow ula jaanqaadaysaa substrate-ka SiC, taasoo yaraynaysa foorarsiga iyo dildilaaca wafer-ka.

3. Xasiloonida Kiimikada

Xasilloon heerkul sare iyo jawi kala duwan (H₂, N₂, Ar, NH₃, iwm.).
Iska caabin oksaydh oo aad u fiican, ka hortagga burburka iyo soo saarista walxaha.

4. Waxqabadka Habka

Dusha siman oo cufan ayaa yaraynaysa daadinta walxaha iyo wasakhowga.
Waxay ilaalisaa xasilloonida cabbirka iyo awoodda rarka ka dib isticmaalka muddada dheer.

5. Waxtarka Kharashka

3-5 jeer cimri adeeg ka dheer doonyaha quartz.
Soo noqnoqoshada dayactirka oo yaraata, yaraynta wakhtiga shaqada oo yaraata iyo kharashyada beddelka.

Su'aalaha Badiya La Weydiiyo - Doomaha Wafer-ka ee Silicon Carbide (SiC)

1. Waa maxay doon yar oo SiC ah?

Doonta wafer-ka ee SiC waa side-hawleed semiconductor ah oo laga sameeyay carbide silicon ah oo saafi ah. Waxaa loo isticmaalaa in lagu hayo laguna qaado wafer-yada inta lagu jiro hababka heerkulka sare sida epitaxy, oksaydheynta, faafinta, iyo annealing. Marka la barbardhigo doonyaha quartz-ka dhaqameed, doonyaha wafer-ka ee SiC waxay bixiyaan xasillooni kuleyl oo heer sare ah, wasakheyn hoose, iyo cimri adeeg oo dheer.

2. Maxaad u doorataa doonyaha wafer-ka ah ee SiC halkii aad ka dooran lahayd doomaha quartz-ka?

Iska caabin heerkulka sare: Xasilloon ilaa 1800°C iyo quartz (≤1200°C).
Isbarbardhig CTE oo ka wanaagsan: Ku dhow substrates-ka SiC, iyadoo la yareynayo cadaadiska wafer-ka iyo dildilaaca.
