SiC gawo lapansi Dia200mm 4H-N ndi HPSI Silicon carbide

Kufotokozera Kwachidule:

Silicon carbide substrate (SiC wafer) ndi mawonekedwe a semiconductor okhala ndi bandgap omwe ali ndi mawonekedwe abwino kwambiri akuthupi ndi makemikolo, makamaka otsogola kwambiri pakutentha, ma frequency apamwamba, amphamvu kwambiri, komanso malo owunikira kwambiri. 4H-V ndi imodzi mwazinthu zamakristali za silicon carbide. Kuonjezera apo, magawo a SiC ali ndi matenthedwe abwino, zomwe zikutanthauza kuti amatha kutaya kutentha kopangidwa ndi zipangizo panthawi yogwira ntchito, kupititsa patsogolo kudalirika ndi moyo wautali wa zipangizo.

4H-N ndi HPSI ndi polytype ya silicon carbide (SiC), yokhala ndi mawonekedwe a crystal lattice opangidwa ndi mayunitsi a hexagonal opangidwa ndi ma atomu anayi a kaboni ndi ma silicon anayi. Kapangidwe kameneka kamapangitsa zinthuzo kukhala ndikuyenda bwino kwa ma elekitironi komanso mawonekedwe amagetsi owonongeka. Pakati pa ma polytypes onse a SiC, 4H-N ndi HPSI amagwiritsidwa ntchito kwambiri pamagetsi amagetsi chifukwa cha ma elekitironi oyenerera komanso kuyenda kwa dzenje komanso kuwongolera kwapamwamba kwamafuta.

Kutuluka kwa magawo a 8inch SiC kumayimira kupita patsogolo kwakukulu kwamakampani opanga mphamvu zamagetsi. Zida zachikhalidwe za silicon-based semiconductor zimatsika kwambiri pakuchita bwino kwambiri ngati kutentha kwambiri komanso ma voltages apamwamba, pomwe magawo a SiC amatha kukhalabe ndi magwiridwe antchito abwino kwambiri. Poyerekeza ndi ma substrates ang'onoang'ono, magawo a 8inch SiC amapereka malo okulirapo opangira chidutswa chimodzi, chomwe chimatanthawuza kupanga bwino kwambiri komanso kutsika mtengo, kofunikira pakuyendetsa malonda aukadaulo wa SiC.

Ukadaulo wakukula kwa magawo a 8inch silicon carbide (SiC) umafunikira kulondola kwambiri komanso kuyera. Ubwino wa gawo lapansi umakhudza mwachindunji magwiridwe antchito a zida zotsatila, kotero opanga ayenera kugwiritsa ntchito matekinoloje apamwamba kuti atsimikizire kukwanira kwa kristalo komanso kusalimba kwapang'onopang'ono kwa magawo. Izi nthawi zambiri zimaphatikizapo njira zovuta zopangira vapor deposition (CVD) ndi kukula kwa kristalo ndi njira zodulira. Magawo a 4H-N ndi HPSI SiC amagwiritsidwa ntchito kwambiri pamagetsi amagetsi, monga osinthira mphamvu zamagetsi, ma inverters oyendetsa magalimoto amagetsi, komanso makina opangira mphamvu zamagetsi.

Titha kupereka gawo lapansi la 4H-N 8inch SiC, magawo osiyanasiyana a magawo ang'onoang'ono. Tithanso kukonza makonda malinga ndi zosowa zanu. Takulandilani kufunsa!
