Gallium Nitride (GaN) Epitaxial Yakula pa Sapphire Wafers 4inch 6inch kwa MEMS
Katundu wa GaN pa Sapphire Wafers
● Mwachangu:Zipangizo zochokera ku GaN zimapereka mphamvu zochulukirapo kasanu kuposa zida zopangira silicon, kupititsa patsogolo magwiridwe antchito amagetsi osiyanasiyana, kuphatikiza RF amplification ndi optoelectronics.
● Wide Bandgap:Gulu lalikulu la GaN limapangitsa kuti pakhale kutentha kwapamwamba kwambiri, ndikupangitsa kuti ikhale yabwino kwambiri pamagetsi apamwamba komanso othamanga kwambiri.
●Kukhalitsa:Kutha kwa GaN kuthana ndi zovuta kwambiri (kutentha kwambiri ndi ma radiation) kumapangitsa kuti pakhale nthawi yayitali m'malo ovuta.
●Kukula Kwakung'ono:GaN imalola kupanga zida zophatikizika komanso zopepuka poyerekeza ndi zida zachikhalidwe zama semiconductor, kuwongolera zamagetsi zing'onozing'ono komanso zamphamvu kwambiri.
Ndemanga
Gallium Nitride (GaN) ikuwoneka ngati semiconductor yosankha pazosankha zapamwamba zomwe zimafunikira mphamvu yayikulu komanso magwiridwe antchito, monga ma module a RF kutsogolo, njira zolumikizirana zothamanga kwambiri, ndi kuyatsa kwa LED. GaN epitaxial wafers, akamakula pazigawo za safiro, amapereka kusinthasintha kwapamwamba kwa kutentha, mphamvu ya breakdown, komanso kuyankha pafupipafupi, zomwe ndizofunikira kwambiri pazida zoyankhulirana zopanda zingwe, ma radar, ndi ma jammers. Zophika izi zimapezeka mu mainchesi 4 ndi mainchesi 6, okhala ndi makulidwe osiyanasiyana a GaN kuti akwaniritse zofunikira zosiyanasiyana zaukadaulo. Katundu wapadera wa GaN umapangitsa kukhala woyenera tsogolo lamagetsi amagetsi.

Q&A
Q1: Kodi maubwino otani ogwiritsira ntchito GaN kuposa ma semiconductors amtundu wa silicon?
A1: GaN imapereka maubwino angapo ofunikira kuposa silicon, kuphatikiza bandgap yokulirapo, yomwe imalola kuti izitha kuthana ndi ma voltages osweka kwambiri ndikugwira ntchito bwino pakutentha kwambiri. Izi zimapangitsa kuti GaN ikhale yabwino pamagetsi apamwamba, othamanga kwambiri ngati ma module a RF, amplifiers mphamvu, ndi ma LED. Kutha kwa GaN kuthana ndi kachulukidwe kamphamvu kamagetsi kumathandizanso zida zing'onozing'ono komanso zogwira mtima kwambiri poyerekeza ndi njira zina zopangira silicon.
Q2: Kodi GaN pa Sapphire wafers angagwiritsidwe ntchito mu MEMS (Micro-Electro-Mechanical Systems)?
A2: Inde, zowotcha za GaN pa Sapphire ndizoyenera kugwiritsa ntchito MEMS, makamaka komwe mphamvu yayikulu, kukhazikika kwa kutentha, ndi phokoso lochepa zimafunikira. Kukhazikika kwa zinthuzo komanso kuchita bwino m'malo othamanga kwambiri kumapangitsa kuti zikhale zoyenera kwa zida za MEMS zomwe zimagwiritsidwa ntchito polumikizirana opanda zingwe, zomverera, ndi makina a radar.
Q3: Ndi ntchito ziti zomwe GaN angagwiritse ntchito polumikizana opanda zingwe?
A3: GaN imagwiritsidwa ntchito kwambiri m'ma module akutsogolo a RF olumikizirana opanda zingwe, kuphatikiza zomangamanga za 5G, makina a radar, ndi ma jammers. Kuchulukitsitsa kwake kwamphamvu komanso kutentha kwamafuta kumapangitsa kuti ikhale yabwino kwambiri pazida zamphamvu kwambiri, zothamanga kwambiri, zomwe zimathandizira magwiridwe antchito komanso mawonekedwe ang'onoang'ono poyerekeza ndi mayankho a silicon.
Q4: Kodi nthawi zotsogola ndi kuchuluka kocheperako kwa GaN pa zowotcha za Sapphire ndi ziti?
A4: Nthawi zotsogola ndi kuchuluka kocheperako kumasiyanasiyana kutengera kukula kwake, makulidwe a GaN, ndi zofunikira zamakasitomala. Chonde titumizireni mwachindunji kuti mudziwe zambiri zamitengo ndi kupezeka kwake kutengera zomwe mukufuna.
Q5: Kodi ndingapeze makulidwe a GaN wosanjikiza kapena milingo ya doping?
A5: Inde, timapereka makonda a GaN makulidwe ndi milingo ya doping kuti ikwaniritse zosowa zenizeni. Chonde tidziwitseni zomwe mukufuna, ndipo tidzakupatsani yankho logwirizana.
