Zvivakwa zveGaN paSapphire Wafers
●Kugona Kwepamusoro:GaN-yakavakirwa michina inopa simba rakapetwa kashanu pane silicon-based zvishandiso, inosimudzira mashandiro mune akasiyana emagetsi maapplication, anosanganisira RF amplification uye optoelectronics.
●Wide Bandgap:Iyo yakakura bandgap yeGaN inogonesa kushanda kwepamusoro patembiricha yakakwira, ichiita kuti ive yakanaka kune yakakwirira-simba uye yakakwirira-frequency application.
●Durability:Kugona kweGaN kubata zvakanyanya mamiriro (tembiricha yakakwira nemwaranzi) inovimbisa kushanda kwenguva refu munzvimbo dzakaoma.
●Simbe:GaN inobvumira kugadzirwa kweakawanda compact uye lightweight zvishandiso zvichienzaniswa neyechinyakare semiconductor zvinhu, kufambisa zvidiki uye zvine simba zvemagetsi.
Abstract
Gallium Nitride (GaN) iri kubuda semiconductor yesarudzo yemhando yepamusoro inoda simba repamusoro uye kushanda zvakanaka, seRF yekumberi-kuguma modules, high-speed communication systems, uye LED chiedza. GaN epitaxial wafers, kana akakurira pasapphire substrates, anopa musanganiswa wepamusoro wekushisa conductivity, high breakdown voltage, uye wide frequency response, zvinova zvakakosha pakushanda kwakakwana mumagetsi ekukurukurirana asina waya, radar, uye jammers. Aya mawafer anowanikwa mune ese 4-inch uye 6-inch madhayamita, ane akasiyana maGaN ukobvu kuti asangane nehunyanzvi zvinodiwa. GaN yakasarudzika zvivakwa inoita kuti ive yekutanga mumiriri kune ramangwana remagetsi emagetsi.

Q&A
Q1: Ndeapi mabhenefiti akakosha ekushandisa GaN pamusoro pechinyakare silicon-based semiconductors?
A1: GaN inopa akawanda akakosha mabhenefiti pamusoro pesilicon, kusanganisira yakafara bhendi, iyo inoibvumira kubata yakakwira kuparara kwemagetsi uye kushanda nemazvo patembiricha yepamusoro. Izvi zvinoita kuti GaN ive yakanaka kune yakakwirira-simba, yakakwirira-frequency application seRF modules, magetsi amplifiers, uye LEDs. Kugona kweGaN kubata akakwira simba density zvakare inogonesa zvidiki uye zvinoshanda zvakanyanya zvichienzaniswa nesilicon-based dzimwe nzira.
Q2: Ko GaN paSapphire wafers inogona kushandiswa muMEMS (Micro-Electro-Mechanical Systems) application?
A2: Ehe, GaN paSapphire wafers inokodzera maMEMS application, kunyanya panodiwa simba repamusoro, kugadzikana kwetembiricha, uye ruzha rwakaderera. Kusimba kwechinyorwa uye kushanda zvakanaka munzvimbo dzakakwirira-frequency inoita kuti ive yakanakira MEMS zvishandiso zvinoshandiswa mukutaurirana zvisina waya, kunzwa, uye radar masisitimu.
Q3: Ndeapi angangove mashandisirwo eGaN mukutaurirana pasina waya?
A3: GaN inoshandiswa zvakanyanya muRF kumberi-kuguma modules yekutaurirana isina waya, kusanganisira 5G zvivakwa, radar masisitimu, uye jammers. Yayo yakakwirira simba density uye yekupisa conductivity inoita kuti ive yakakwana kune yakakwirira-simba, yakakwirira-frequency zvishandiso, inogonesa kuita zvirinani uye madiki fomu zvinhu zvichienzaniswa nesilicon-based mhinduro.
Q4: Ndedzipi nguva dzekutungamira uye hushoma hwekurongeka huwandu hweGaN paSapphire wafers?
A4: Nguva dzekutungamira uye hushoma hwemaodha huwandu hunosiyana zvichienderana newafer size, GaN ukobvu, uye zvakanangana nevatengi zvinodiwa. Ndapota taura nesu zvakananga kuti uwane zvakadzama mitengo uye kuwanikwa kwakavakirwa pane zvaunotaura.
Q5: Ndingawana here tsika GaN layer ukobvu kana doping mazinga?
A5: Ehe, isu tinopa kugadzirisa kweGaN ukobvu uye doping mazinga kuti asangane nezvinodiwa zvekushandisa. Ndokumbira tizivise zvaunoda mataurirwo, uye isu tinokupa mhinduro yakaenderana.
