GaN Epitaxy

ʻO ka wehewehe pōkole:

He pōhaku kihi ʻo GaN Epitaxy i ka hana ʻana i nā mea hana semiconductor kiʻekiʻe, e hāʻawi ana i ka maikaʻi maikaʻi, ka paʻa wela, a me ka hilinaʻi. Hoʻopili ʻia nā ʻōnaehana GaN Epitaxy a Semicera e hoʻokō i nā koi o nā noi ʻokiʻoki, e hōʻoia ana i ka maikaʻi a me ka kūlike i kēlā me kēia papa.

Semicerahaʻaheo e hōʻike i kona ʻokiʻokiGaN Epitaxynā lawelawe, i hoʻolālā ʻia e hoʻokō i nā pono e ulu mau ana o ka ʻoihana semiconductor. ʻO Gallium nitride (GaN) kahi mea i ʻike ʻia no kāna mau waiwai kūʻokoʻa, a ʻo kā mākou kaʻina ulu epitaxial e hōʻoia i ka hoʻokō piha ʻana o kēia mau pono i kāu mau polokalamu.

Nā Layer GaN Hana Kiʻekiʻe Semicerakūikawā i ka hana ʻana i nā mea kiʻekiʻeGaN Epitaxynā papa, e hāʻawi ana i ka hoʻomaʻemaʻe waiwai ʻole a me ka pololei o ke kūkulu ʻana. He mea koʻikoʻi kēia mau papa no nā noi like ʻole, mai ka uila uila a hiki i ka optoelectronics, kahi e pono ai ka hana ʻoi aku ka maikaʻi a me ka hilinaʻi. ʻO kā mākou ʻenehana ulu pololei e hōʻoia i kēlā me kēia papa GaN e hoʻokō i nā kūlana kūpono i koi ʻia no nā mea ʻoki ʻoki.

Hoʻonui ʻia no ka ponoʻO kaGaN Epitaxyhāʻawi ʻia e Semicera i hoʻonohonoho pono ʻia e hoʻomaikaʻi i ka pono o kāu mau mea uila. Ma ka hāʻawi ʻana i nā papa GaN haʻahaʻa haʻahaʻa, hoʻomaʻemaʻe kiʻekiʻe, hiki iā mākou ke hana i nā mea hana i nā alapine kiʻekiʻe a me nā voltages, me ka emi ʻana o ka mana. He kī kēia no nā noi e like me nā transistors high-electron-mobility (HEMTs) a me nā diodes light-emitting (LEDs), kahi i ʻoi aku ka maikaʻi.

Loaʻa i nā mea hoʻohana nui Semicera'sGaN Epitaxyhe mea maʻalahi, e mālama ana i kahi ākea o nā ʻoihana a me nā noi. Ke hoʻomohala nei ʻoe i nā mea hoʻonui mana, nā ʻāpana RF, a i ʻole nā ​​diodes laser, hāʻawi kā mākou GaN epitaxial layers i ke kumu e pono ai no nā mea hana kiʻekiʻe a hilinaʻi. Hiki ke hoʻopili ʻia kā mākou kaʻina hana e hoʻokō i nā koi kikoʻī, e hōʻoia i ka loaʻa ʻana o kāu huahana i nā hopena maikaʻi loa.

Hoʻoholo i ka maikaʻiʻO ka maikaʻi ka pōhaku kihi oSemicera'o ka hookokoke ana maiGaN Epitaxy. Hoʻohana mākou i nā ʻenehana ulu epitaxial kiʻekiʻe a me nā kaʻina hoʻomalu maikaʻi e hana i nā papa GaN e hōʻike ana i ka kūlike maikaʻi loa, nā haʻahaʻa haʻahaʻa haʻahaʻa, a me nā waiwai waiwai. ʻO kēia kūpaʻa i ka maikaʻi e hōʻoiaʻiʻo ʻaʻole i hui wale kāu mau hāmeʻa akā ʻoi aku i nā kūlana ʻoihana.
