Gallium Nitride (GaN) Epitaxial Grown on Sapphire Wafers 4inch 6inch for MEMS

Kufotokozera Kwachidule:

Gallium Nitride (GaN) pa ma wafer a Sapphire imapereka magwiridwe antchito osayerekezeka pakugwiritsa ntchito ma frequency apamwamba komanso amphamvu kwambiri, zomwe zimapangitsa kuti ikhale chinthu choyenera kugwiritsa ntchito ma module amtsogolo a RF (Radio Frequency) a m'badwo wotsatira, magetsi a LED, ndi zida zina za semiconductor.GaNMakhalidwe apamwamba amagetsi a GaN, kuphatikizapo bandgap yayikulu, amalola kuti igwire ntchito pamagetsi ndi kutentha kwakukulu kuposa zida zachikhalidwe zopangidwa ndi silicon. Pamene GaN ikugwiritsidwa ntchito kwambiri kuposa silicon, ikuyendetsa patsogolo zamagetsi zomwe zimafuna zipangizo zopepuka, zamphamvu, komanso zogwira mtima.

Katundu wa GaN pa Ma Wafer a Sapphire

●Kugwira Ntchito Mwachangu:Zipangizo zochokera ku GaN zimapereka mphamvu yochulukirapo kasanu kuposa zipangizo zochokera ku silicon, zomwe zimapangitsa kuti magwiridwe antchito azigwira ntchito m'njira zosiyanasiyana zamagetsi, kuphatikizapo RF amplification ndi optoelectronics.
●Chingwe Chokulirapo:Kusiyana kwakukulu kwa GaN kumalola kuti igwire bwino ntchito kutentha kwambiri, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito ndi mphamvu zambiri komanso pafupipafupi.
●Kulimba:Kutha kwa GaN kuthana ndi mavuto oopsa (kutentha kwambiri ndi kuwala kwa dzuwa) kumatsimikizira kuti zinthu zikuyenda bwino kwa nthawi yayitali m'malo ovuta.
● Kukula Kakang'ono:GaN imalola kupanga zipangizo zazing'ono komanso zopepuka poyerekeza ndi zipangizo zachikhalidwe za semiconductor, zomwe zimathandiza kuti zamagetsi zazing'ono komanso zamphamvu zikhalepo.

Chidule

Gallium Nitride (GaN) ikuonekera ngati semiconductor yosankhidwa kwambiri pa ntchito zapamwamba zomwe zimafuna mphamvu zambiri komanso magwiridwe antchito, monga ma module a RF front-end, machitidwe olumikizirana mwachangu, ndi magetsi a LED. Ma wafer a GaN epitaxial, akamakula pazidutswa za safiro, amapereka kuphatikiza kwa kutentha kwambiri, magetsi owonongeka kwambiri, komanso mayankho afupipafupi, zomwe ndizofunikira kwambiri pakugwira ntchito bwino kwa zida zolumikizirana zopanda zingwe, ma radar, ndi ma jammer. Ma wafer awa amapezeka m'ma diameter a mainchesi 4 ndi mainchesi 6, okhala ndi makulidwe osiyanasiyana a GaN kuti akwaniritse zofunikira zosiyanasiyana zaukadaulo. Kapangidwe kapadera ka GaN kamapangitsa kuti ikhale yoyenera kwambiri mtsogolo mwa zamagetsi zamagetsi.

Mafunso ndi Mayankho

Q1: Kodi ubwino waukulu wogwiritsa ntchito GaN kuposa ma semiconductors achikhalidwe okhala ndi silicon ndi uti?

A1: GaN imapereka maubwino angapo ofunikira kuposa silicon, kuphatikiza bandgap yayikulu, yomwe imalola kuti igwire ntchito ndi ma voltages okwera kwambiri ndikugwira ntchito bwino kutentha kwambiri. Izi zimapangitsa GaN kukhala yoyenera kugwiritsa ntchito mphamvu zambiri monga ma RF modules, ma amplifier amphamvu, ndi ma LED. Kutha kwa GaN kuthana ndi mphamvu zambiri kumathandizanso kuti zipangizo zazing'ono komanso zogwira mtima kwambiri poyerekeza ndi njira zina zochokera ku silicon.

Q2: Kodi ma wafer a GaN pa Sapphire angagwiritsidwe ntchito mu MEMS (Micro-Electro-Mechanical Systems)?

A2Inde, GaN pa ma wafer a Sapphire ndi oyenera kugwiritsidwa ntchito pa MEMS, makamaka komwe kumafunika mphamvu zambiri, kukhazikika kwa kutentha, komanso phokoso lochepa. Kulimba kwa chipangizochi komanso kugwira ntchito bwino kwake m'malo omwe ali ndi ma frequency ambiri kumapangitsa kuti chikhale choyenera kugwiritsa ntchito zida za MEMS zomwe zimagwiritsidwa ntchito polumikizirana opanda zingwe, kumvera, ndi makina a radar.

Q3: Kodi GaN ingagwiritsidwe ntchito bwanji pakulankhulana opanda zingwe?

A3: GaN imagwiritsidwa ntchito kwambiri mu ma module a RF front-end polumikizirana opanda zingwe, kuphatikiza zomangamanga za 5G, makina a radar, ndi ma jammer. Mphamvu yake yayikulu komanso kutentha kwake zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito zida zamphamvu kwambiri, zomwe zimapangitsa kuti ikhale yogwira ntchito bwino komanso zinthu zazing'ono poyerekeza ndi mayankho ochokera ku silicon.

Q4: Kodi nthawi yotsogolera ndi kuchuluka kocheperako koyitanitsa kwa GaN pa ma wafer a Sapphire ndi iti?

A4: Nthawi yogulira ndi kuchuluka kwa oda yocheperako zimasiyana malinga ndi kukula kwa wafer, makulidwe a GaN, ndi zosowa za makasitomala enaake. Chonde titumizireni mwachindunji kuti mudziwe zambiri zamitengo ndi kupezeka kwake kutengera zomwe mukufuna.

Q5: Kodi ndingapeze makulidwe a GaN layer kapena milingo ya doping?

A5Inde, timapereka kusintha kwa makulidwe a GaN ndi milingo ya doping kuti tikwaniritse zosowa zinazake za pulogalamuyo. Chonde tidziwitseni zomwe mukufuna, ndipo tidzakupatsani yankho loyenera.
