O nei uiga e faia ai le 8-inisi silicon carbide substrates e taua tele le faʻaaogaina i le gaosiga o masini eletise eletise maualuga, maualuga-televave, ma le malosi.
8inch silicon carbide wafer e tele fa'aoga.
1. Masini eletise: SiC wafers o loʻo faʻaaogaina lautele i le gaosiga o masini eletise eletise e pei ole mana MOSFETs (metal-oxide-semiconductor field-effect transistors), Schottky diodes, ma modules integration power. Ona o le maualuga o le vevela, le maualuga o le malepelepe, ma le maualuga o le eletise eletise o le SiC, o nei masini e mafai ona ausia lelei, faʻaleleia le malosi o le liua i le maualuga o le vevela, maualuga-voltage, ma le maualuga o siosiomaga.
2. Optoelectronic masini: SiC wafers e taua tele i masini optoelectronic, faʻaaogaina e gaosia ai photodetectors, laser diodes, ultraviolet sources, ma isi mea sili atu o mata ma mea faʻaeletoroni sili a Silicon carbide e avea ma mea e filifilia, aemaise lava i talosaga e manaʻomia ai le vevela maualuga, maualuga maualuga, ma maualuga maualuga maualuga.
3. Radio Frequency (RF) Devices: E faʻaaogaina foi meataalo SiC e gaosia ai masini RF e pei o RF power amplifiers, suiga maualuga, RF sensors, ma isi mea. O le maualuga o le mafanafana o le SiC, uiga maualuga-televave, ma le maualalo o le gau e lelei ai mo talosaga RF e pei o fesoʻotaʻiga uaealesi ma faʻaogaina o le radar.
4. High-veamera eletise: Ona o le maualuga o le vevela ma le vevela elasticity, o loʻo faʻaogaina le SiC wafers e gaosia ai mea faʻaeletoroni ua fuafuaina e faʻaogaina i totonu o siosiomaga vevela maualuga, e aofia ai le maualuga o le vevela eletise eletise, masini, ma faʻatonutonu.
O auala autu o talosaga o le 8-inisi silicon carbide substrate 4H-N ituaiga e aofia ai le gaosiga o le maualuga-vevela, maualuga-tele, ma le maualuga-mana eletise masini, aemaise lava i le fanua o taavale faaeletonika, malosi o le la, gaosiga o le matagi, eletise. locomotives, servers, mea faigaluega fale, ma taavale eletise. E le gata i lea, o masini e pei o SiC MOSFETs ma Schottky diodes ua faʻaalia lelei le faʻatinoga i le fesuiaʻiina o alalaupapa, faʻataʻitaʻiga puʻupuʻu, ma faʻaogaina faʻaogaina, faʻaaogaina i le eletise eletise.
XKH e mafai ona faʻavasegaina ma mafiafia eseese e tusa ai ma manaʻoga o tagata faʻatau. O lo'o maua ni togafitiga fa'alilolilo eseese. Eseese ituaiga o doping (pei o le nitrogen doping) e lagolagoina. E mafai e le XKH ona tuʻuina atu le lagolago faʻapitoa ma faʻatalanoaga auaunaga e faʻamautinoa ai e mafai e tagata faʻatau ona foia faʻafitauli i le faagasologa o le faʻaaogaina. O le 8-inisi silicon carbide substrate ei ai tulaga lelei tele i tulaga o le faʻaitiitia o tau ma le faʻateleina o le gafatia, lea e mafai ona faʻaititia le tau o le iunite e tusa ma le 50% pe a faʻatusatusa i le 6-inisi substrate. E le gata i lea, o le faateleina o le mafiafia o le substrate 8-inisi e fesoasoani e faʻaitiitia ai le faʻaogaina o le geometrical ma le faʻaogaina o le pito i le taimi o masini, ma faʻaleleia atili ai fua.
