50.8mm 2inch GaN ku-sapphire Epi-layer wafer

Incazelo emfushane:

Njengengxenye yesithathu yesizukulwane se-semiconductor, i-gallium nitride inezinzuzo zokumelana nokushisa okuphezulu, ukuhambisana okuphezulu, ukuguquguquka okuphezulu kwe-thermal kanye negebe elibanzi lebhendi. Ngokwezinto ezihlukene ze-substrate, amashidi e-gallium nitride epitaxial angahlukaniswa abe izigaba ezine: i-gallium nitride esekelwe ku-gallium nitride, i-silicon carbide esekelwe ku-gallium nitride, i-sapphire based gallium nitride kanye ne-silicon based gallium nitride. I-silicon-based gallium nitride epitaxial sheet iwumkhiqizo osetshenziswa kakhulu onezindleko eziphansi zokukhiqiza kanye nobuchwepheshe bokukhiqiza obuvuthiwe.

Ukusetshenziswa kweshidi le-gallium nitride GaN epitaxial

Ngokusekelwe ekusebenzeni kwe-gallium nitride, ama-chips e-gallium nitride epitaxial afaneleka kakhulu amandla aphezulu, imvamisa ephezulu, kanye nezicelo ze-voltage ephansi.

Kubonakala ku:

I-1) I-bandgap ephezulu: I-bandgap ephezulu ithuthukisa izinga le-voltage yamadivayisi we-gallium nitride futhi ingakhipha amandla aphezulu kunamadivayisi e-gallium arsenide, afaneleka ngokukhethekile iziteshi eziyisisekelo zokuxhumana ze-5G, i-radar yezempi nezinye izinkambu;

I-2) Ukusebenza kahle kokuguqulwa okuphezulu: ukumelana nokumelana kwe-gallium nitride switching power electronics ama-oda angu-3 obukhulu obuphansi kunalawo we-silicon, okunganciphisa kakhulu ukulahlekelwa ekushintsheni;

I-3) I-conductivity ephezulu yokushisa: ukushisa okuphezulu kwe-gallium nitride kwenza kube nokusebenza okuhle kakhulu kokukhipha ukushisa, okulungele ukukhiqizwa kwamandla aphezulu, izinga lokushisa eliphezulu kanye nezinye izinkambu zamadivayisi;

I-4) Amandla ensimu kagesi yokuwohloka: Nakuba amandla ensimu kagesi ewohlokayo ye-gallium nitride eseduze naleyo ye-silicon nitride, ngenxa yenqubo ye-semiconductor, ukungafani kwe-lattice yezinto ezibonakalayo nezinye izici, ukubekezelelwa kwamandla kagesi kumadivayisi we-gallium nitride kuvame ukuba ngu-1000V, kanti I-voltage yokusebenzisa ephephile ngokuvamile ingaphansi kuka-650V.
