Habka dhigista uumiga waa in lagu shubo kaarbiid silikoon dusha sare ee substrate-ka iyada oo loo marayo falcelinta uumiga kiimikaad ee heerkul sarreeya, taas oo samaynaysa filim silikoon carbide ah oo nadiif ah oo nadiif ah ama qaybo dhismeed. Labadan tignoolajiyada waxay leeyihiin faa'iidooyin iyaga u gaar ah. Habka sintering budada ah ayaa ku haboon wax soo saarka ballaaran oo leh qiimo jaban, halka habka kaydinta uumiga uu bixin karo nadiif sare iyo qaab dhismeedka cufan, waxaana si ballaaran loo isticmaalaa goobta semiconductor.

2. Qalabka alaabta eeceramics silicon carbide recrystalized

Sifada cajiibka ah ee ceramics silikoon carbide recrystalized waa waxqabadkeeda ugu wanagsan ee jawiga heerkulka sare. Meesha dhalaalaysa ee maaddadani waa mid aad u sareysa ilaa 2700C, waxayna leedahay awood farsamo oo wanaagsan heerkulka sare. Intaa waxaa dheer, carbide silicon recrystalized sidoo kale waxay leedahay iska caabin oksaydheyn heer sare ah iyo iska caabin daxalka, oo waxay ku sii ahaan kartaa mid deggan jawi kiimiko ah oo aad u daran. Sidaa darteed, ceramics RSiC ayaa si weyn loogu isticmaalay dhinacyada foornooyinka kulaylka sareeyo, walxaha heerkulka sare leh, iyo qalabka kiimikada.

Intaa waxaa dheer, carbide silicon recrystalized waxay leedahay kuleyl heer sare ah waxayna si wax ku ool ah u qaban kartaa kulaylka, taas oo ka dhigaysa inay leedahay qiimo codsi muhiim ahreactors MOCVDiyo qalabka daawaynta kulaylka ee wax soo saarka wafer semiconductor. Xakamaynta kulaylka sare iyo iska caabbinta shoogga kulaylka waxay hubisaa hawlgalka lagu kalsoonaan karo ee qalabka ee xaaladaha daran.

3. Goobaha codsiga ee ceramics silicon carbide recrystalized

Wax-soo-saarka Semiconductor: Warshadaha semiconductor-ka, ceramics silicon carbide recrystallized ayaa loo isticmaalaa in lagu soo saaro substrates iyo taageerooyinka reactors MOCVD. Sababtoo ah iska caabbinta heerkulka sare, caabbinta daxalka, iyo kuleylka kuleylka sarreeya, qalabka RSiC waxay ilaalin karaan waxqabadka xasilloon ee jawiga falcelinta kiimikada adag, hubinta tayada iyo dhalidda waferrada semiconductor.

Warshadaha sawir-qaadista: Warshadaha sawir-qaadista, RSiC waxaa loo isticmaalaa in lagu soo saaro qaab-dhismeedka taageerada qalabka koritaanka crystal. Maaddaama koritaanka crystal loo baahan yahay in lagu sameeyo heerkul sare inta lagu jiro habka wax soo saarka ee unugyada photovoltaic, caabbinta kulaylka ee carbide silicon recrystallized waxay hubisaa hawlgalka xasilloon ee muddada dheer ee qalabka.

Foornooyinka kulaylka sareeyo: ceramics RSiC sidoo kale waxaa si weyn loogu isticmaalaa foornooyinka kulaylka sareeyo, sida dahaarka iyo qaybaha foornooyinka faakuumka, foornooyinka dhalaalay iyo qalab kale. Iska caabbinta shoogga kulaylka iyo iska caabbinta oksaydhka ayaa ka dhigaysa mid ka mid ah walxaha aan la bedeli karin ee warshadaha heerkulka sare.

4. Jihada cilmi-baarista ee ceramics silikoon carbide recrystalized

Iyada oo baahida sii kordheysa ee agabka waxqabadka sare leh, jihada cilmi baarista ee ceramics silikoon carbide recrystalized ayaa si tartiib tartiib ah u caddaatay. Cilmi-baarista mustaqbalka waxay diiradda saari doontaa dhinacyada soo socda:

Hagaajinta nadiifinta alaabta: Si loo buuxiyo shuruudaha nadiifnimada sare ee semiconductor iyo goobaha sawir-qaadista, cilmi-baarayaashu waxay sahamiyaan siyaabaha lagu hagaajinayo nadiifnimada RSiC iyada oo la wanaajinayo tignoolajiyada kaydinta uumiga ama soo bandhigida alaabta ceeriin cusub, taas oo kor u qaadeysa qiimaha codsiga ee goobahan farsamada sare. .

Hagaajinta qaab-dhismeedka yar-yar: Iyada oo la xakameynayo xaaladaha sinnaanta iyo qaybinta qaybaha budada, qaab-dhismeedka yar-yar ee carbide silicon recrystallized ayaa la sii wanaajin karaa, taas oo kor u qaadeysa sifooyinka farsamada iyo caabbinta shoogga kuleylka.

Qalabka isku dhafan ee shaqeynaya: Si loola qabsado jawiga isticmaalka kakan, cilmi-baarayaashu waxay isku dayayaan in ay isku daraan RSiC iyo qalab kale si ay u horumariyaan qalabyo isku dhafan oo leh sifooyin kala duwan, sida qalabyo isku dhafan oo ku salaysan silicon carbide oo leh caabbinta xirashada sare iyo korantada korantada.

5. Gabagabo

Maaddaama wax-qabad heer sare ah, ceramics silicon carbide recrystalized ayaa si ballaaran loo isticmaalay meelo badan sababtoo ah sifooyinka wanaagsan ee heerkulka sare, caabbinta oksaydhka iyo iska caabinta daxalka. Cilmi-baarista mustaqbalka waxay diiradda saari doontaa hagaajinta nadiifinta walxaha, hagaajinta qaab-dhismeedka yar-yar iyo horumarinta agabyo shaqeynaya oo isku dhafan si loo daboolo baahiyaha warshadaha sii kordhaya. Iyada oo loo marayo hal-abuurkan tignoolajiyada, ceramics-ka silikoon carbide ee dib loo soo celiyay ayaa la filayaa in ay door weyn ka ciyaaraan dhinacyo badan oo tignoolajiyada sare ah.
