100mm 4inihi GaN i runga i te Sapphire Epi-layer wafer Gallium nitride epitaxial wafer
Ko te tukanga tipu o GaN puru LED hanganga puna quantum. Ko nga rerenga tukanga taipitopito e whai ake nei
(1) Te tunu kai teitei, ka wera tuatahi te taputapu hapira ki te 1050 ℃ i roto i te hau hauwai, ko te kaupapa ko te horoi i te mata o te tïpako;
(2) Ka heke te pāmahana o te tïpako ki te 510 ℃, ka tukuna he paparanga parepare GaN/AlN iti-mahana me te matotoru o te 30nm ki runga i te mata o te taputapu sapphire;
(3) Ka piki ake te pāmahana ki te 10 ℃, ka werohia te haukini hau tauhohenga, te trimethylgallium me te silane, e whakahaere ana i te tere o te rere e rite ana, a ka tipuhia te GaN-momo-gaN o te 4um te matotoru;
(4) Ko te hau tauhohenga o te konumohe trimethyl me te gallium trimethyl i whakamahia ki te whakarite i nga konitineta N-momo A⒑ silicon-doped me te matotoru o te 0.15um;
(5) 50nm Zn-doped InGaN i whakaritea ma te werohia te trimethylgallium, te trimethylindium, te diethylzinc me te haukini i te mahana o te 8O0 ℃ me te whakahaere i nga rerenga rere rereke;
(6) I whakanuia te pāmahana ki te 1020 ℃, trimethylaluminum, trimethylgallium me bis (cyclopentadienyl) konupora i werohia hei whakarite i te 0.15um Mg doped P-momo AlGaN me te 0.5um Mg doped P-momo G te huka toto;
(7) Ko te ahua P-momo GaN Sibuyan kiriata teitei i whiwhihia ma te whakauru i te hau hauota i te 700 ℃;
(8) Te tuhi i runga i te mata stasis P-momo G hei whakaatu i te mata stasis N-momo G;
(9) Te whakaetonga o nga pereti whakapiri Ni/Au i runga i te mata p-GaNI, te whakaetonga o nga pereti whakapiri △/Al i runga i te mata ll-GaN hei hanga i nga hiko.
