Gallium Nitride (GaN) Epitaxial Yakakura paSapphire Wafers 4inch 6inch yeMEMS

Tsananguro pfupi:

Gallium Nitride (GaN) iri pamaSapphire wafers inopa mashandiro asina kuenzana ekushandisa mafrequency akawanda uye simba guru, zvichiita kuti ive chinhu chakakodzera mamodule eRF (Radio Frequency) echizvarwa chinotevera, marambi eLED, nezvimwe zvishandiso zve semiconductor.GaNHunhu hwepamusoro hwemagetsi, kusanganisira bandgap yakakwira, inobvumira kuti ishande pamagetsi akawandisa uye tembiricha dzakanyanya kupfuura zvishandiso zvechinyakare zvesilicon. Sezvo GaN iri kushandiswa zvakanyanya pane silicon, iri kukurudzira kufambira mberi mune zvemagetsi zvinoda zvinhu zvakareruka, zvine simba, uye zvinoshanda.

Zvimiro zveGaN paSapphire Wafers

●Kushanda Nesimba Kwakanyanya:Midziyo yakagadzirwa neGaN inopa simba rakapetwa kashanu pane michina yakagadzirwa nesilicon, zvichiwedzera kushanda kwayo mumabasa akasiyana-siyana emagetsi, kusanganisira RF amplification uye optoelectronics.
●Bandgap Yakafara:Gap rakafara reGaN rinoita kuti ishande zvakanaka pakupisa kwakakwira, zvichiita kuti ive yakakodzera kushandiswa kwesimba guru uye mafrequency akakwira.
●Kugara kwenguva refu:Kugona kweGaN kubata nemamiriro ezvinhu akaipisisa (kupisa kwakanyanya uye mwaranzi) kunoita kuti ishande kwenguva refu munzvimbo dzakaoma.
●Saizi diki:GaN inobvumira kugadzirwa kwemidziyo midiki uye yakareruka zvichienzaniswa nezvinhu zvechinyakare zve semiconductor, zvichiita kuti zvive nyore kugadzira michina midiki uye ine simba.

Pfupiso

Gallium Nitride (GaN) iri kubuda senzira yekusarudzwa kwemhando yepamusoro yekushandisa simba rakawanda uye kushanda zvakanaka, senge maRF front-end modules, masisitimu ekukurukurirana anomhanya, uye mwenje we LED. Mawafer eGaN epitaxial, kana akakura pamidziyo yesafire, anopa musanganiswa wekupisa kwakanyanya, voltage yakakwira, uye wide frequency response, izvo zvakakosha pakushanda zvakanaka mumidziyo yekutaurirana isina waya, ma radar, uye ma jammer. Mawafer aya anowanikwa mu 4-inch ne 6-inch dhayamita, ane ukobvu hwakasiyana hweGaN kuti asvike kune zvinodiwa zvakasiyana zvehunyanzvi. Hunhu hwakasiyana hweGaN hunoita kuti ive mukana mukuru weramangwana remagetsi emagetsi.

Mibvunzo neMhinduro

Mubvunzo 1: Ndedzipi zvakanakira zvekushandisa GaN pane zvechinyakare zve silicon-based semiconductors?

A1: GaN ine mabhenefiti akawanda akakosha kupfuura silicon, kusanganisira bandgap yakakura, iyo inoibvumira kubata ma voltages akanyanya kukanganiswa uye kushanda zvinobudirira pakupisa kwakanyanya. Izvi zvinoita kuti GaN ive yakakodzera kune ma applications ane simba rakawanda, akadai seRF modules, power amplifiers, uye LEDs. Kugona kwaGaN kubata simba rakawanda kunoitawo kuti zvishandiso zvidiki uye zvishande zvakanaka zvichienzaniswa nezvimwe zvinoshandiswa nesilicon.

Mubvunzo wechipiri: Ko GaN iri paSapphire wafers inogona kushandiswa here muMEMS (Micro-Electro-Mechanical Systems) applications?

A2: Ehe, GaN paSapphire wafers yakakodzera kushandiswa kweMEMS, kunyanya kana paine simba rakawanda, kugadzikana kwekupisa, uye ruzha rwakaderera. Kugara kwenguva refu uye kushanda zvakanaka kwezvinhu izvi munzvimbo dzine frequency yakakwira zvinoita kuti zvive zvakanaka kumidziyo yeMEMS inoshandiswa mukutaurirana kwewaya, kunzwa, uye radar systems.

Mubvunzo wechitatu: Ndezvipi zvingangoshandiswa neGaN mukutaurirana kusina waya?

A3: GaN inoshandiswa zvakanyanya mumaRF front-end modules ekutaurirana pasina waya, kusanganisira 5G infrastructure, radar systems, uye jammers. Simba rayo guru uye thermal conductivity zvinoita kuti ive yakakwana kune zvishandiso zvine simba guru, high-frequency, zvichiita kuti ishande zvakanaka uye mafomu madiki zvichienzaniswa nemhinduro dzinobva kusilicon.

Mubvunzo wechina: Ndeipi nguva yekutungamira uye huwandu hushoma hweodha yeGaN pamaSapphire wafers?

A4: Nguva dzekutengesa zvinhu uye huwandu hushoma hweodha zvinosiyana zvichienderana nehukuru hwewafer, ukobvu hweGaN, uye zvinodiwa nevatengi. Ndapota taurai nesu zvakananga kuti muwane mitengo yakadzama uye kuwanikwa zvichienderana nezvamunoda.

Mubvunzo 5: Ndingawana ukobvu hweGaN layer kana mazinga edoping here?

A5: Ehe, tinopa kugadzirisa ukobvu hweGaN uye huwandu hwedoping kuti zvienderane nezvinodiwa zvekushandisa. Ndapota tizivisei zvamunoda, uye tichakupai mhinduro yakagadzirirwa.
