4 Inisi GaN i luga ole SiC Wafer

Fa'amatalaga Puupuu:

VET Energy's 4-inisi GaN i luga o le SiC wafer o se oloa fa'afouina i le fanua o eletise eletise. O lenei wafer e tuʻufaʻatasia ai le faʻaogaina lelei o le vevela o le silicon carbide (SiC) faʻatasi ai ma le maualuga o le malosi ma le maualalo o le gau o le gallium nitride (GaN), ma avea ai ma se filifiliga lelei mo le faia o masini maualuga, maualuga. E fa'amautinoa e le VET Energy le fa'atinoga lelei ma le fa'atumauina o le wafer e ala ile fa'atekonolosi epitaxial maualuga ole MOCVD.

Fa'amatalaga Oloa

Faailoga o oloa

Ole laina ole oloa ole VET Energy e le gata ile GaN ile SiC wafers. Matou te tuʻuina atu foʻi le tele o mea faʻapipiʻi semiconductor substrate, e aofia ai le Si Wafer, SiC Substrate, SOI Wafer, SiN Substrate, Epi Wafer, ma isi. Wafer, e faʻafetaui ai le manaʻoga eletise eletise i le lumanaʻi mo masini faʻatinoina maualuga.

O le VET Energy e tu'uina atu auaunaga fa'apitoa e fetu'una'i, ma e mafai ona fa'avasega GaN epitaxial layers o mafiafia eseese, ituaiga o doping, ma lapopo'a eseese e tusa ai ma mana'oga patino o tagata fa'atau. E le gata i lea, matou te tuʻuina atu foʻi le lagolago faʻapitoa faʻapolofesa ma le maeʻa o le faʻatau atu auaunaga e fesoasoani ai i tagata faʻatau e vave ona atiaʻe masini eletise eletise maualuga.
