ʻO Gallium Nitride (GaN) Epitaxial i ulu ʻia ma nā Sapphire Wafers 4 ʻīniha 6 ʻīniha no MEMS
Nā Waiwai o GaN ma nā Wafers Sapphire
● Ka Hana Kiʻekiʻe:Hāʻawi nā mea hana GaN i ʻelima manawa ʻoi aku ka mana ma mua o nā mea hana silicon, e hoʻonui ana i ka hana ma nā noi uila like ʻole, me ka hoʻonui ʻana o RF a me nā optoelectronics.
● Pālahalaha ākea:ʻO ka laulā ākea o GaN e hiki ai i ka hana kiʻekiʻe ma nā mahana kiʻekiʻe, e kūpono ia no nā noi mana kiʻekiʻe a me ke alapine kiʻekiʻe.
●Paʻa:ʻO ka hiki o GaN ke lawelawe i nā kūlana koʻikoʻi (nā mahana kiʻekiʻe a me ka radiation) e hōʻoiaʻiʻo ana i ka hana lōʻihi ma nā ʻano ʻino.
●Nui liʻiliʻi:ʻAe ʻo GaN i ka hana ʻana o nā mea liʻiliʻi a māmā hoʻi i hoʻohālikelike ʻia me nā mea semiconductor kuʻuna, e hoʻomaʻamaʻa ana i nā mea uila liʻiliʻi a ikaika hoʻi.

Ke kū mai nei ʻo Gallium Nitride (GaN) ma ke ʻano he semiconductor koho no nā noi holomua e koi ana i ka mana kiʻekiʻe a me ka pono, e like me nā modula RF front-end, nā ʻōnaehana kamaʻilio wikiwiki, a me nā kukui LED. ʻO nā wafers epitaxial GaN, i ka wā i ulu ʻia ma nā substrates sapphire, hāʻawi i ka hui pū ʻana o ka conductivity thermal kiʻekiʻe, ka voltage breakdown kiʻekiʻe, a me ka pane alapine ākea, ʻo ia ke kī no ka hana maikaʻi loa i nā polokalamu kamaʻilio uea ʻole, nā radar, a me nā jammers. Loaʻa kēia mau wafers i nā diameters 4-ʻīniha a me 6-ʻīniha, me nā mānoanoa GaN like ʻole e hoʻokō i nā koi loea like ʻole. ʻO nā waiwai kūikawā o GaN e hoʻolilo iā ia i moho mua no ka wā e hiki mai ana o nā mea uila mana.

Q1: He aha nā pono koʻikoʻi o ka hoʻohana ʻana iā GaN ma mua o nā semiconductors silicon-based kuʻuna?
A1Hāʻawi ʻo GaN i kekahi mau pono koʻikoʻi ma luna o ka silicon, me kahi bandgap ākea, e hiki ai iā ia ke lawelawe i nā voltages breakdown kiʻekiʻe a hana pono i nā mahana kiʻekiʻe. ʻO kēia ka mea e kūpono ai ʻo GaN no nā noi mana kiʻekiʻe, alapine kiʻekiʻe e like me nā modula RF, nā amplifiers mana, a me nā LED. ʻO ka hiki o GaN ke lawelawe i nā densities mana kiʻekiʻe e hiki ai i nā mea liʻiliʻi a ʻoi aku ka maikaʻi i hoʻohālikelike ʻia me nā koho ʻē aʻe i hoʻokumu ʻia i ka silicon.
Q2: Hiki ke hoʻohana ʻia ʻo GaN ma nā wafers Sapphire i nā noi MEMS (Micro-Electro-Mechanical Systems)?
A2ʻAe, kūpono nā wafers GaN ma Sapphire no nā noi MEMS, ʻoiai kahi e pono ai ka mana kiʻekiʻe, ke kūpaʻa o ka mahana, a me ka walaʻau haʻahaʻa. ʻO ke kūpaʻa a me ka pono o ka mea i nā wahi alapine kiʻekiʻe e kūpono ia no nā mea MEMS i hoʻohana ʻia i ke kamaʻilio uea ʻole, ka ʻike ʻana, a me nā ʻōnaehana radar.
Q3: He aha nā hoʻohana kūpono o GaN i ke kamaʻilio uea ʻole?
A3Hoʻohana nui ʻia ʻo GaN i nā modula RF front-end no ke kamaʻilio uea ʻole, me ke kahua 5G, nā ʻōnaehana radar, a me nā jammers. ʻO kona nui o ka mana a me ka conductivity thermal e kūpono ia no nā mea hana mana kiʻekiʻe, alapine kiʻekiʻe, e hiki ai ke hana maikaʻi aʻe a me nā kumu ʻano liʻiliʻi i hoʻohālikelike ʻia me nā hoʻonā silicon-based.
Q4: He aha nā manawa alakaʻi a me nā nui kauoha liʻiliʻi loa no GaN ma nā wafers Sapphire?
A4ʻOkoʻa nā manawa alakaʻi a me nā nui o nā kauoha liʻiliʻi ma muli o ka nui o ka wafer, ka mānoanoa o GaN, a me nā koi kikoʻī o ka mea kūʻai aku. E ʻoluʻolu e kelepona pololei mai iā mākou no nā kumukūʻai kikoʻī a me ka loaʻa e pili ana i kāu mau kikoʻī.
Q5: Hiki iaʻu ke loaʻa ka mānoanoa o ka papa GaN maʻamau a i ʻole nā pae doping?
A5ʻAe, hāʻawi mākou i ka hoʻopilikino ʻana o ka mānoanoa o GaN a me nā pae doping e hoʻokō i nā pono noi kikoʻī. E ʻoluʻolu e hoʻomaopopo iā mākou i kāu mau kikoʻī i makemake ʻia, a e hāʻawi mākou i kahi hopena i hana kūikawā ʻia.
