50.8mm 2inch GaN i luga o le safaira Epi-layer wafer

Fa'amatalaga Puupuu:

I le avea ai ma se vaega lona tolu o mea semiconductor, gallium nitride o loʻo i ai le lelei o le maualuga o le vevela, maualuga le fesoʻotaʻiga, maualuga le vevela ma le lautele o le va.E tusa ai ma mea eseese substrate, gallium nitride epitaxial laupepa e mafai ona vaevaeina i ni vaega se fa: gallium nitride e faʻavae i luga o le gallium nitride, silicon carbide based gallium nitride, safaira faʻavae gallium nitride ma silicon based gallium nitride.Silicon-based gallium nitride epitaxial sheet o le oloa sili ona faʻaaogaina ma le maualalo o tau gaosiga ma tekinolosi gaosiga matutua.

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, e 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.
