SiC dahaarka garaafka MOCVD Wafer sidayyaal
-SiCGraphiteWafer, Kaarboonku waxa uu keenaa wax-qabadyada, susceptors epitaxy, Graphite-ku waxa uu keenaa dhibbanayaasha, Susceptors Wafer Graphite, https://www.vet-china.com/sic-coating-graphite-mocvd-wafer-carriers-2.html#:~:text=SicGraphiteSusceptors-, SicGraphiteTrays,
Daahan CVD-SiC waxa uu leeyahay sifooyinka qaab-dhismeedka lebis, alaabta is haysta, iska caabin heerkulka sare, iska caabin oksaydhka, daahirsanaan sare, caabbinta acid & alkali iyo reagent organic, leh guryaha deggan iyo kiimikaad.
Marka la barbar dhigo qalabka garaafyada sare ee nadiifka ah, graphite wuxuu bilaabaa inuu oxidize at 400C, taas oo keeni doonta luminta budada sababtoo ah oksaydheynta, taasoo keentay wasakhowga deegaanka ee aaladaha durugsan iyo qolalka faakuumka, iyo kordhinta wasakhda deegaanka saafiga ah.
Si kastaba ha noqotee, daahan SiC wuxuu ilaalin karaa xasilloonida jirka iyo kiimikaad ee 1600 darajo, Waxaa si weyn loogu isticmaalaa warshadaha casriga ah, gaar ahaan warshadaha semiconductor.
Shirkadeena waxay bixisaa adeegyada habka daahan SiC ee habka CVD ee dusha sare ee graphite, ceramics iyo alaabta kale, si gaasaska gaarka ah ee ay ku jiraan kaarboon iyo silikoon ay uga falceliyaan heerkulka sare si ay u helaan nadiifnimada sare ee SiC molecules, molecules deposited on the dusha alaabta dahaarka ah, samaynta lakabka ilaalinta SIC. SIC-ga la sameeyay waxay si adag ugu xidhan tahay saldhigga garaafka, iyadoo siinaya saldhigga garaafyada sifooyin gaar ah, sidaas darteed samaynta dusha sare ee garaafka, Porosity-free, caabbinta heerkulka sare, caabbinta daxalka iyo caabbinta oksaydhka.
Tilmaamaha ugu muhiimsan:
1. Iska caabbinta oksaydhka heerkulka sare:
caabbinta oksaydhisku weli aad bay u wanaagsan tahay marka heerkulku gaadho 1700 C.
2. Nadiifin sare: oo ay samaysay uumiga kiimikaad ee hoos yimaada xaalada koloriinaynta heerkulka sare.
3. Iska caabinta nabaadguurka: adkaanta sare, dusha sare, qaybo yaryar.
4. Iska caabinta daxalka: acid, alkali, milix iyo reagents organic.
