2inch 50.8mm Silicon Carbide SiC Wafers Doped Si N-type Production Research ndi Dummy grade

Zinthu zoyambira: 4H silicon carbide (4H-SiC)

Kapangidwe ka kristalo: tetrahexahedral (4H)

Kupereka mankhwala osokoneza bongo: Osagwiritsidwa ntchito (4H-N)

Kukula: mainchesi awiri

Mtundu wa ma conductivity: Mtundu wa N (wopangidwa ndi n)

Kuyendetsa: Semiconductor

Chiyembekezo cha Msika: Ma wafer a SiC osapangidwa ndi dope a 4H-N ali ndi zabwino zambiri, monga kutentha kwambiri, kutayika kochepa kwa conduction, kukana kutentha kwambiri, komanso kukhazikika kwa makina, motero ali ndi chiyembekezo chachikulu pamsika pakugwiritsa ntchito zamagetsi zamagetsi ndi ma RF. Ndi chitukuko cha mphamvu zongowonjezwdwa, magalimoto amagetsi ndi kulumikizana, pali kufunikira kwakukulu kwa zida zogwira ntchito bwino, kutentha kwambiri komanso kulekerera mphamvu zambiri, zomwe zimapatsa mwayi waukulu pamsika wa ma wafer a SiC osapangidwa ndi dope a 4H-N.

Ntchito: Ma wafer a SiC osapangidwa ndi dope a mainchesi awiri a 4H-N angagwiritsidwe ntchito kupanga zida zosiyanasiyana zamagetsi zamagetsi ndi zida za RF, kuphatikiza koma osati kokha:

1--4H-SiC MOSFETs: Ma transistors a metal oxide semiconductor field effect omwe amagwiritsidwa ntchito pa mphamvu yapamwamba/kutentha kwambiri. Zipangizozi zimakhala ndi kutayika kochepa kwa conduction ndi switching kuti zipereke magwiridwe antchito komanso kudalirika kwambiri.

2--4H-SiC JFETs: Ma Junction FET a RF power amplifier ndi switching applications. Zipangizozi zimapereka magwiridwe antchito apamwamba komanso kukhazikika kwa kutentha kwambiri.

Ma Diode a 3--4H-SiC Schottky: Ma Diode a mphamvu yapamwamba, kutentha kwambiri, komanso kugwiritsa ntchito pafupipafupi kwambiri. Zipangizozi zimapereka magwiridwe antchito apamwamba komanso kutayika kochepa kwa conduction ndi switching.

Zipangizo zamagetsi za 4--4H-SiC: Zipangizo zomwe zimagwiritsidwa ntchito m'malo monga ma laser diode amphamvu kwambiri, ma UV detectors ndi ma optoelectronic integrated circuits. Zipangizozi zili ndi mphamvu zambiri komanso ma frequency ambiri.

Mwachidule, ma wafer a SiC osapangidwa ndi ma inchi awiri a 4H-N ali ndi kuthekera kogwiritsidwa ntchito m'njira zosiyanasiyana, makamaka pa zamagetsi zamagetsi ndi RF. Kugwira ntchito kwawo bwino komanso kukhazikika kwa kutentha kwambiri kumapangitsa kuti akhale opikisana kwambiri m'malo mwa zipangizo zachikhalidwe za silicon kuti azigwiritsa ntchito zinthu zapamwamba, kutentha kwambiri komanso mphamvu zambiri.
