Waa maxay daahan silikoon carbide ah?

daahan Silicon carbide,Caadi ahaan loo yaqaan daahan SiC, waxa loola jeedaa habka lagu dabaqayo lakabka carbide silikoon dushiisa iyada oo loo marayo habab ay ka mid yihiin Dhigista Uumiga Kiimikada (CVD), Dhigista Uumiga Jirka (PVD), ama buufin kuleyl ah. Daahan silikoon carbide dhoobada dhoobada waxay wanaajisaa sifooyinka dusha sare ee substrates kala duwan iyadoo siinaysa caabbinta xidhashada gaarka ah, xasiloonida kulaylka, iyo ilaalinta daxalka. SiC waxay caan ku tahay astaamaheeda sare ee jirka iyo kiimikaad, oo ay ku jiraan meel dhalaalaysa oo sare (qiyaastii 2700℃), engegnaanta xad dhaafka ah (Miisaanka Mohs 9), daxalka iyo iska caabinta oksaydhka ee heersare ah, iyo waxqabadka xad dhaafka ah.

Faa'iidooyinka Muhiimka ah ee Dahaarka Silicon Carbide ee Codsiyada Warshadaha

Astaamahan awgeed, daahan silikoon carbide ah ayaa si weyn loogu isticmaalaa beeraha sida hawada hawada, qalabka hubka, iyo farsamaynta semiconductor. Deegaannada aadka u daran, gaar ahaan inta u dhaxaysa 1800-2000 ℃, dahaarka SiC wuxuu muujinayaa xasillooni kuleyl oo cajiib ah iyo iska caabin, taasoo ka dhigaysa mid ku habboon codsiyada heerkul sare. Si kastaba ha noqotee, silikoon carbide oo keliya ayaa ka maqan daacadnimada qaab dhismeedka looga baahan yahay codsiyo badan, sidaa darteed hababka dahaarka ayaa loo shaqeeyaa si ay uga faa'iidaystaan ​​​​sifadeeda gaarka ah iyada oo aan la wiiqin awoodda qaybta. Wax soo saarka semiconductor, walxaha dahaarka leh ee silikoon carbide waxay bixiyaan ilaalin la isku halayn karo iyo xasilloonida waxqabadka gudaha qalabka loo isticmaalo hababka MOCVD.

Hababka caadiga ah ee Diyaarinta Dahaarka Silicon Carbide

Ⅰ● Dhigista Uumiga Kiimikada (CVD) Dahaarka Silikon Kaarbide

Habkan, dahaarka SiC waxaa lagu sameeyay iyadoo la gelinayo substrates qolka falcelinta, halkaasoo methyltrichlorosilane (MTS) u dhaqmo sidii horudhac. Xaaladaha la kantaroolo-sida caadiga ah 950-1300 ° C iyo cadaadis taban-MTS-ku wuxuu maraa burbur, iyo carbide silicon ayaa lagu shubaa dusha sare. Habkan daahan CVD SiC wuxuu hubinayaa daahan cufan, lebis ah oo leh u hoggaansanaan aad u wanaagsan, oo ku habboon codsiyada saxda ah ee sare ee qaybaha semiconductor iyo aerospace.

Ⅱ● Habka Beddelka Hore (Polymer Impregnation iyo Pyrolysis - PIP)

Habka kale ee buufinta silikoon carbide ee waxtarka leh waa habka beddelka hore, kaas oo ku lug leh galinta muunada horay loo daaweeyay ee xalka hore ee dhoobada. Ka dib markii la faaruqiyo haanta impregnation oo cadaadis saaray daahan, muunad waa la kululeeyaa, taasoo keentay in daahan silicon carbide samaynta marka la qaboojiyo. Habkani waxa loo door bidaa qaybaha u baahan dhumucdiisuna tahay daahan isku mid ah iyo adkaysiga xidhashada la xoojiyey.

Astaamaha Jirka ee Dahaarka Silicon Carbide

Dahaarka Silicon carbide waxay soo bandhigaan sifooyin ka dhigaya kuwo ku habboon dalabaadka codsiyada warshadaha. Guryahaan waxaa ka mid ah:

Heerarka kulaylka: 120-270 W/m·K
Isku-dhafka Balaadhinta kulaylka: 4.3 × 10^^(-6)/K (20 ~ 800 ℃)
Iska caabin koronto: 10^⁵- 10^⁶Ω·cm
Adag: Miisaanka Mohs 9

Codsiyada Dahaarka Silicon Carbide

Wax soo saarka semiconductor, daahan silikoon carbide ah ee MOCVD iyo hababka kale ee heerkulka sare waxay ilaalinayaan qalabka muhiimka ah, sida reactors iyo susceptors, iyagoo siinaya iska caabin heerkul sare ah iyo xasilooni labadaba. Hawada hawada iyo difaaca, dahaarka dhoobada silikoon carbide waxaa lagu dabaqaa qaybaha ay tahay inay u adkeystaan ​​saameynta xawaaraha sare leh iyo bay'ada daxaleysiga. Intaa waxaa dheer, rinjiga silikoon carbide ama dahaarka ayaa sidoo kale loo isticmaali karaa aaladaha caafimaadka ee u baahan adkeysi marka loo eego hababka jeermiska.

Waa maxay sababta loo doorto dahaarka Silicon Carbide?

Iyada oo la xaqiijiyay in la kordhinayo nolosha qayb ka mid ah, dahaarka silikoon carbide waxay bixiyaan adkeysi aan isbarbardhig lahayn iyo xasilloonida heerkulka, taas oo ka dhigaysa kharash-ool ah isticmaalka muddada dheer. Adigoo dooranaya dusha dahaarka leh ee silikoon carbide ah, warshaduhu waxay ka faa'iideysteen kharashaadka dayactirka oo hoos u dhacay, kalsoonida qalabka oo la xoojiyay, iyo hufnaanta hawleed oo la hagaajiyay.
