I-8Inch 200mm 4H-N SiC Wafer Ibanga lophando lwe-dummy

8Inch 200mm 4H-N SiC Wafer Ibanga lophando dummy olubonakalayo

Inkcazelo emfutshane:

Njengoko ezothutho, amandla kunye neemarike zemizi-mveliso zikhula, imfuno yezinto ezithembekileyo, ezisebenza ngamandla e-elektroniki ziyaqhubeka ukukhula. Ukuhlangabezana neemfuno zentsebenzo ephuculweyo ye-semiconductor, abavelisi besixhobo bajonge kwi-wide bandgap semiconductor materials, ezifana ne-4H SiC Prime Grade portfolio yethu ye-4H n -type silicon carbide (SiC) wafers.

Iithegi zeMveliso

Ngenxa yeempawu zayo ezizodwa kunye ne-elektroniki, i-200mm SiC wafer semiconductor imathiriyeli isetyenziselwa ukwenza ukusebenza okuphezulu, ubushushu obuphezulu, ukumelana nemitha, kunye nezixhobo zombane ezisebenza kakhulu. Ixabiso le-substrate ye-8inch SiC liyehla ngokuthe ngcembe njengoko itekhnoloji ihambela phambili ngakumbi kwaye imfuno ikhula. Uphuhliso lwetekhnoloji yakutsha nje lukhokelela ekuvelisweni kwesikali sokwenziwa kwee-wafers ze-SiC ezingama-200mm. Iinzuzo eziphambili ze-SiC wafer semiconductor materials xa kuthelekiswa ne-Si kunye ne-GaAs wafers: Amandla ombane ombane we-4H-SiC ngexesha lokuphuka kwe-avalanche ingaphezulu komyalelo wobukhulu obuphezulu kunexabiso elihambelanayo le-Si kunye ne-GaAs. Oku kukhokelela ekunciphiseni okubonakalayo kwi-restivity ye-Ron. I-Low-state resistivity, idityaniswe noxinano oluphezulu lwangoku kunye ne-thermal conductivity, ivumela ukusetyenziswa kokufa okuncinci kakhulu kwizixhobo zamandla. I-conductivity ephezulu ye-thermal ye-SiC inciphisa ukuxhathisa kwe-thermal ye-chip. Iimpawu ze-elektroniki zezixhobo ezisekelwe kwii-wafers ze-SiC zizinzile kakhulu ngexesha kunye neqondo lokushisa elizinzileyo, eliqinisekisa ukuthembeka okuphezulu kweemveliso. I-silicon carbide ixhathisa ngokugqithiseleyo kwi-radiation enzima, engayithobiyo i-electronic properties ye-chip. Iqondo lokushisa eliphezulu elilinganiselweyo le-crystal (ngaphezu kwe-6000C) likuvumela ukuba wenze izixhobo ezinokwethenjelwa kakhulu kwiimeko zokusebenza ezinzima kunye nezicelo ezizodwa. Okwangoku, sinokubonelela ngee-wafers ezincinci ze-200mmSiC ngokuthe ngcembe kwaye ngokuqhubekayo kwaye sibe nesitokhwe kwindawo yokugcina.
