4 Inchi GaN pa SiC Wafer

Kufotokozera Kwachidule:

VET Energy's 4-inch GaN pa SiC wafer ndi chinthu chosintha pazamagetsi zamagetsi. Chophika ichi chimaphatikiza matenthedwe abwino kwambiri a silicon carbide (SiC) yokhala ndi mphamvu zambiri komanso kutayika kochepa kwa gallium nitride (GaN), kupangitsa kuti ikhale chisankho choyenera kupanga zida zothamanga kwambiri, zamphamvu kwambiri. VET Energy imatsimikizira kugwira ntchito bwino komanso kusasinthika kwa chophikacho kudzera muukadaulo wapamwamba wa MOCVD epitaxial.

Mzere wazogulitsa wa VET Energy sungokhala ku GaN pa zowotcha za SiC. Timaperekanso zida zingapo za semiconductor gawo lapansi, kuphatikiza Si Wafer, SiC Substrate, SOI Wafer, SiN Substrate, Epi Wafer, ndi zina zotero. Kuphatikiza apo, tikupanganso zida zatsopano za semiconductor, monga Gallium Oxide Ga2O3 ndi AlN. Wafer, kuti akwaniritse zofuna zamakampani amagetsi amagetsi amtsogolo pazida zogwira ntchito kwambiri.

VET Energy imapereka ntchito zosinthika makonda, ndipo imatha kusintha magawo a GaN epitaxial makulidwe osiyanasiyana, mitundu yosiyanasiyana ya ma doping, ndi makulidwe osiyanasiyana ophatikizika malinga ndi zosowa za makasitomala. Kuphatikiza apo, timaperekanso chithandizo chaukadaulo chaukadaulo komanso ntchito yotsatsa pambuyo pogulitsa kuti tithandizire makasitomala kupanga zida zamagetsi zamagetsi zogwira ntchito kwambiri.
