O le P-ituaiga SiC wafer, 4H / 6H-P 3C-N, faʻatasi ai ma lona 6-inisi le tele ma le 350 μm mafiafia, e taua tele i le gaosiga o pisinisi o eletise eletise maualuga. O lona fa'aogaina lelei o le vevela ma le maualuga o le eletise malepelepe e lelei mo le gaosiga o vaega e pei o suiga o le eletise, diodes, ma transistors fa'aaogaina i siosiomaga maualuga-vevela e pei o ta'avale eletise, eletise eletise, ma malosiaga fa'afouina. O le malosi o le wafer e fa'atino lelei i tulaga faigata e fa'amautinoa ai le fa'atuatuaina o le fa'atinoga i mea tau alamanuia e mana'omia ai le maualuga o le malosi ma le malosi. E le gata i lea, o lona tulaga muamua mafolafola fesoasoani i le faʻaogaina saʻo i le taimi o le faʻaogaina o masini, faʻaleleia le lelei o le gaosiga ma le tutusa o oloa.
O mea lelei ole N-type SiC composite substrates e aofia ai
- Amioga vevela maualuga: P-ituaiga SiC wafers e fa'amama lelei le vevela, fa'apena lelei mo talosaga maualuga-vevela.
- Malosi maualuga malepe: Mafai ona tatalia voltages maualuga, faʻamautinoa le faʻamaoni i le eletise eletise ma masini eletise maualuga.
- Tete'e i Siosiomaga Saua: Lelei le tumau i tulaga ogaoga, e pei o le maualuga o le vevela ma siosiomaga pala.
- Fa'aliliuga Malosi'i Lelei: O le P-type doping e faafaigofieina ai le pulea lelei o le mana, ma faia ai le wafer talafeagai mo faiga liua malosi.
- Primary Flat Orientation: Faʻamautinoa le faʻaoga saʻo i le taimi o le gaosiga, faʻaleleia le saʻo ma le faʻaogaina o masini.
- Fua Manifinifi (350 μm): O le mafiafia sili ona lelei o le wafer e lagolagoina ai le tu'ufa'atasia i masini fa'aeletoroni fa'aletonu, avanoa.
I le aotelega, o le P-type SiC wafer, 4H / 6H-P 3C-N, e ofoina atu le tele o tulaga lelei e faʻafaigofie ai mo pisinisi ma faʻaoga eletise. O le maualuga o le vevela ma le malepelepe eletise e mafai ai ona faʻatuatuaina le faʻaogaina i le maualuga o le vevela ma le maualuga-voltage siosiomaga, ae o lona tetee atu i tulaga faigata e mautinoa ai le tumau. O le P-type doping e mafai ai ona lelei le liua o le mana, ma fa'alelei mo le eletise eletise ma le malosi. E le gata i lea, o le fa'ata'ita'iga muamua a le wafer e fa'amautinoa ai le fa'aogaina tonu i le taimi o le gaosiga o le gaosiga, fa'aleleia le fa'amalieina o le gaosiga. Faʻatasi ai ma le mafiafia o le 350 μm, e fetaui lelei mo le tuʻufaʻatasia i masini faʻapitoa, faʻapipiʻi.
