Sharaxaada

Susceptors-garafeedka dahaarka leh ee Semicera's SiC ayaa lagu farsameeyay iyadoo la isticmaalayo substrates garaafyo tayo sare leh, kuwaas oo si taxadar leh loogu dahaadhay Silicon Carbide (SiC) iyada oo loo marayo habab horumarsan oo Kaydinta Kiimikada (CVD). Nashqadan hal-abuurka leh waxay hubisaa iska caabin aan caadi ahayn oo loogu talagalay shoogga kulaylka iyo xaalufka kiimikaad, taasoo si weyn u fidinaysa cimriga Susceptor-garafeedka dahaarka leh ee SiC iyo dammaanad qaadka waxqabadka la isku halayn karo inta lagu jiro habka wax-soo-saarka semiconductor.

Tilmaamaha Muhiimka ah:

1. Habdhaqanka kulaylka sareSusceptor garaafiga dahaarka leh ee SiC waxa uu soo bandhigaa kuleyl heer sare ah, kaas oo muhiim u ah kulaylka wax ku ool ah inta lagu jiro wax soo saarka semiconductor. Habkani waxa uu yareeyaa heerkulbeegyada kulaylka ee dusha sare ee wafer, iyada oo kor u qaadaysa qaybinta heerkulka isku midka ah ee lagama maarmaanka u ah gaaritaanka sifooyinka semiconductor ee la doonayo.

2. Caabbin Kiimiko Adag iyo Naxdin KululDahaarka SiC wuxuu bixiyaa difaac adag oo ka dhan ah daxalka kiimikaad iyo shoogga kulaylka, isagoo ilaalinaya daacadnimada sawir-qaadista xittaa jawiga habaynta adag. Adkeyntan la xoojiyey waxay yaraynaysaa wakhtiga hoos u dhaca waxayna kordhisaa cimriga, iyada oo gacan ka geysanaysa kor u kaca wax soo saarka iyo waxtarka kharashka ee xarumaha wax soo saarka semiconductor.

3. Habaynta Baahiyaha Gaarka ahSiC-da dahaarka leh ee garaafyada garaafyada ayaa loo habayn karaa si ay u buuxiyaan shuruudaha iyo doorbidyada gaarka ah. Waxaan bixinaa xulashooyin kala duwan oo habeyn ah, oo ay ku jiraan hagaajinta cabbirka iyo kala duwanaanshaha dhumucda daahan, si loo hubiyo dabacsanaanta naqshadeynta iyo waxqabadka la wanaajiyey ee codsiyada kala duwan iyo cabbirrada nidaamka.

Codsiyada:
