Umusaruro wa substrate ya SiC ya santimetero 3.5 (Diameter 76.2mm 4H-N)

Ibintu by'ingenzi bigize wafer za silicon carbide mosfet za santimetero 3 ni ibi bikurikira;

Silicon Carbide (SiC) ni ibikoresho bya semiconductor bifite umuvuduko munini, birangwa no gutwara ubushyuhe bwinshi, kugenda cyane kwa electron, no gukomera cyane k'amashanyarazi. Ibi bituma SiC wafers zidasanzwe mu gukoresha ingufu nyinshi, inshuro nyinshi, no mu bushyuhe bwinshi. Cyane cyane muri polytype ya 4H-SiC, imiterere yayo ya kristalo itanga imikorere myiza ya elegitoroniki, bigatuma iba ibikoresho bikundwa cyane mu bikoresho by'ikoranabuhanga bikoresha ingufu.

Wafer ya Silicon Carbide 4H-N ya santimetero 3 ni wafer irimo azote ifite amashanyarazi yo mu bwoko bwa N. Ubu buryo bwo gukoresha doping buha wafer electron nyinshi, bityo byongera imikorere y'amashanyarazi y'igikoresho. Ingano ya wafer, ifite santimetero 3 (umurambararo wa mm 76.2), ni ingano ikoreshwa cyane mu nganda za semiconductor, ikwiriye ibikorwa bitandukanye byo gukora.

Wafer ya Silicon Carbide 4H-N ya santimetero 3 ikorwa hakoreshejwe uburyo bwa Physical Vapor Transport (PVT). Ubu buryo burimo guhindura ifu ya SiC mo kristu imwe ku bushyuhe bwinshi, bigatuma kristu ikora neza kandi ikagira ubwiza bumwe. Byongeye kandi, ubunini bwa wafer busanzwe bugera kuri mm 0.35, kandi ubuso bwayo bushyirwamo irangi ry’uruhande rubiri kugira ngo igere ku rwego rwo hejuru cyane rwo kugororoka no koroha, ibi bikaba ari ingenzi mu bikorwa bikurikira byo gukora semiconductor.

Ingano y'ikoreshwa rya wafer ya Silicon Carbide 4H-N ya santimetero 3 ni nini, harimo ibikoresho by'ikoranabuhanga bikoresha ingufu nyinshi, sensor zikoresha ubushyuhe bwinshi, ibikoresho bya RF, n'ibikoresho bya optoelectronic. Imikorere yayo myiza n'ubwizerwe bituma ibi bikoresho bikorana neza mu bihe bikomeye, bigahaza ibyifuzo by'ibikoresho bya semiconductor bikoresha ingufu nyinshi mu nganda zigezweho z'ikoranabuhanga.

Dushobora gutanga substrate ya 4H-N ya 3inch SiC, ubwoko butandukanye bwa wafers za substrate. Dushobora kandi gutegura uburyo bwo guhindura ibintu ukurikije ibyo ukeneye. Murakaza neza!
