50.8mm 2inch GaN i luga o le safaira Epi-layer wafer
Fa'aogaina o le gallium nitride GaN epitaxial pepa
Faʻavae i luga o le faʻatinoga o le gallium nitride, gallium nitride epitaxial chips e sili ona talafeagai mo le malosi maualuga, maualuga taimi, ma le maualalo o le eletise.
E atagia i:
1) High bandgap: O le bandgap maualuga e faʻaleleia ai le maualuga o le eletise o masini gallium nitride ma e mafai ona maua ai le malosi maualuga atu nai lo masini gallium arsenide, lea e sili ona talafeagai mo nofoaga autu o fesoʻotaʻiga 5G, radar militeri ma isi fanua;
2) Faʻaleleia maualuga le faʻaliliuina: o le on-resistance o le gallium nitride switching power electronic device e 3 poloaiga o le maualuga maualalo ifo nai lo masini silicon, lea e mafai ona faʻaitiitia ai le gau i luga o le suiga;
3) O le maualuga o le vevela: o le maualuga o le vevela o le gallium nitride e maua ai le lelei o le faʻaogaina o le vevela, talafeagai mo le gaosiga o le malosi maualuga, maualuga-vevela ma isi vaega o masini;
4) Faʻaleagaina le malosi o le eletise: E ui lava o le malepelepe o le eletise eletise o le gallium nitride e latalata ile silicon nitride, ona o le semiconductor process, mea lattice mismatch ma isi mea, o le faʻapalepale eletise o masini gallium nitride e masani lava ile 1000V, ma le saogalemu fa'aoga voltage e masani lava i lalo ole 650V.
