Mfundo Yopanga ya Silicon Carbide (SiC) gawo lapansi lophika

Silicon Carbide (SiC) gawo lapansi lophika limapangidwa kudzera mu Physical Vapor Transport (PVT) kapena njira zokulirapo. Njirayi imayamba ndi chiyero chapamwamba cha SiC ufa wodzaza mu graphite crucible. Potentha kwambiri kuposa 2,000 ° C komanso malo oyendetsedwa bwino, ufawo umasungunuka kukhala nthunzi ndikuyikanso pa kristalo wambewu yoyang'ana mosamala, ndikupanga ingot yayikulu, yopanda vuto lochepa.

SiC boule ikakula, imadutsa:

Kudula kwa Ingot: Macheka a waya wa diamondi olondola amadula ingot ya SiC kukhala zowotcha kapena tchipisi.

Kupukutira ndi kugaya: Pamwamba pake amaphwanyidwa kuti achotse macheka ndikukwaniritsa makulidwe ofanana.

Chemical Mechanical Polishing (CMP): Imafika pagalasi lokonzekera bwino epi yokhala ndi roughness yotsika kwambiri.

Doping yosankha: Nayitrojeni, aluminiyamu, kapena doping ya boron imatha kuyambitsidwa kuti igwirizane ndi magetsi (mtundu wa n kapena p-mtundu).

Kuyang'anira Ubwino: Advanced metrology imawonetsetsa kuti wafer flatness, makulidwe ofanana, ndi kachulukidwe kachilema kumakwaniritsa zofunikira zamakalasi a semiconductor.

Njira iyi yopangira masitepe angapo imabweretsa tchipisi tating'onoting'ono ta 10 × 10mm Silicon Carbide (SiC) zomwe zakonzekera kukula kwa epitaxial kapena kupanga zida zachindunji.

Makhalidwe a Silicon Carbide (SiC) gawo lapansi lophika

Silicon Carbide (SiC) gawo lapansi lophika limapangidwa makamaka ndi4H-SiC or 6H-SiCpolytypes:

4H-SiC:Imakhala ndi ma electron apamwamba, kupangitsa kuti ikhale yabwino pazida zamagetsi monga MOSFETs ndi Schottky diode.
6H-SiC:Amapereka mawonekedwe apadera a RF ndi zida za optoelectronic.

Zofunikira zakuthupi za Silicon Carbide (SiC) gawo lapansi lophika:

Wide bandgap:~ 3.26 eV (4H-SiC) - imathandiza kuti magetsi awonongeke kwambiri komanso kutayika kochepa.
Thermal conductivity:3-4.9 W / cm · K - imachotsa kutentha bwino, kuonetsetsa kuti pakhale bata mu machitidwe apamwamba kwambiri.
Kulimba:~ 9.2 pamlingo wa Mohs - imatsimikizira kulimba kwamakina panthawi yokonza ndikugwiritsa ntchito chipangizocho.

Kugwiritsa ntchito kwa Silicon Carbide (SiC) gawo lapansi lophika

Kusinthasintha kwa gawo laling'ono la Silicon Carbide (SiC) kumawapangitsa kukhala ofunika m'mafakitale angapo:

Zamagetsi Zamagetsi: Maziko a ma MOSFET, IGBT, ndi ma Schottky diode omwe amagwiritsidwa ntchito pamagalimoto amagetsi (EVs), magetsi opangira mafakitale, ndi ma inverters ongowonjezera mphamvu.

SiC imapereka mphamvu ya 10 × yokwera kwambiri, kukana kutentha kwambiri, komanso kutayika kocheperako, ndikupangitsa kuti ikhale yabwino kwambiri, zida zamphamvu kwambiri zomwe silikoni sangathe kuthandizira.

Q2: Kodi gawo laling'ono la 10 × 10mm Silicon Carbide (SiC) lingaperekedwe ndi zigawo za epitaxial?
Inde. Timapereka magawo okonzeka a epi ndipo titha kutumizira zowotcha zokhala ndi makonda a epitaxial kuti zikwaniritse zida zamphamvu kapena zopangira ma LED.

Q3: Kodi kukula kwake ndi magawo a doping alipo?
Mwamtheradi. Pomwe tchipisi ta 10 × 10mm ndizokhazikika pakufufuza ndi kuyesa kwa zida, makulidwe ake, makulidwe, ndi mbiri ya doping zimapezeka mukafunsidwa.

Q4: Kodi zophika izi zimakhala zotalika bwanji m'malo ovuta kwambiri?
SiC imasunga kukhulupirika kwadongosolo komanso magwiridwe antchito amagetsi opitilira 600 ° C komanso pansi pa radiation yayikulu, kupangitsa kuti ikhale yabwino pazamlengalenga ndi zamagetsi zamagulu ankhondo.
