Silicon Carbide SiC Ingot 6inch N mhando Dummy/prime grade thickness inogona kugadziriswa

Tsananguro pfupi:

Silicon Carbide (SiC) chinhu che semiconductor chine bandgap yakakura chiri kuwana kubatwa kwakakosha mumaindasitiri akasiyana-siyana nekuda kwehunhu hwayo hwepamusoro hwemagetsi, kupisa, uye michina. SiC Ingot ine 6-inch N-type Dummy/Prime grade yakagadzirirwa kugadzira zvishandiso zve semiconductor zvepamusoro, kusanganisira mashandisirwo ane simba guru uye mashandisirwo efrequency yepamusoro. Nesarudzo dzehukobvu hunogadziriswa uye matsananguro akajeka, iyi SiC ingot inopa mhinduro yakakodzera yekugadzira zvishandiso zvinoshandiswa mumotokari dzemagetsi, masisitimu emagetsi emaindasitiri, kutaurirana, uye mamwe masevhisi anoshanda zvakanyanya. Kusimba kweSiC mumamiriro emagetsi akakwira, tembiricha yakakwira, uye mafrequency akakwira kunoita kuti ishande kwenguva refu, inoshanda, uye yakavimbika mumashandisirwo akasiyana-siyana.
SiC Ingot inowanikwa muhukuru hwemainji matanhatu, ine dhayamita ye150.25mm ± 0.25mm uye ukobvu hwakakura kupfuura 10mm, zvichiita kuti ive yakakodzera kucheka wafer. Chigadzirwa ichi chinopa kutaridzika kwakanaka kwe4° kuenda ku <11-20> ± 0.2°, zvichiita kuti chigadzirwa chive chakanyatsogadzirwa. Pamusoro pezvo, ingot ine kutaridzika kwakadzikama kwe <1-100> ± 5°, zvichibatsira mukugadzirisa kristalo zvakanaka uye kushanda zvakanaka.
Iine resistivity yakakura iri pakati pe0.015–0.0285 Ω·cm, micropipe density yakaderera ye <0.5, uye mhando yepamusoro yemucheto, iyi SiC Ingot yakakodzera kugadzirwa kwemidziyo yemagetsi inoda zvikanganiso zvishoma uye kushanda kwepamusoro mumamiriro ezvinhu akaomarara.

Mashandisirwo

Magetsi Emagetsi:Iyo ingot yeSiC ine mainches matanhatu inoshandiswa zvakanyanya mukugadzira zvishandiso zvemagetsi zvine simba zvakaita seMOSFET, IGBTs, uye diodes, izvo zvinhu zvakakosha mumasisitimu ekushandura simba. Midziyo iyi inoshandiswa zvakanyanya muma inverters emagetsi (EV), ma industrial motor drives, magetsi, uye masisitimu ekuchengetedza simba. Kugona kweSiC kushanda pama voltages akakwira, ma frequency akakwira, uye tembiricha yakanyanya kunoita kuti ive yakakodzera kushandiswa uko zvishandiso zvechinyakare zvesilicon (Si) zvaizoomerwa nekushanda nemazvo.

Mota dzemagetsi (mota dzemagetsi):Mumotokari dzemagetsi, zvikamu zveSiC zvakakosha pakugadzira mamodule emagetsi muma inverters, ma converters eDC-DC, uye ma charger ari mubhodhi. Kufambiswa kweSiC kwekupisa kwakanyanya kunobvumira kudzikiswa kwekugadzirwa kwekupisa uye kushanda zviri nani mukushandurwa kwesimba, izvo zvakakosha pakuvandudza mashandiro uye huwandu hwekutyaira kwemotokari dzemagetsi. Pamusoro pezvo, zvishandiso zveSiC zvinogonesa zvikamu zvidiki, zvakareruka, uye zvakavimbika, zvichibatsira mukushanda kwese kwema EV systems.

Masisitimu Esimba Rinodzokororwa:Zvishandiso zveSiC zvinhu zvakakosha mukugadzira zvishandiso zvekushandura simba zvinoshandiswa mumasisitimu esimba rinogona kushandiswazve, kusanganisira ma solar inverters, ma wind turbines, uye mhinduro dzekuchengetedza simba. Kugona kweSiC kubata simba zvakanyanya uye kutonga kwakanaka kwekupisa kunoita kuti simba rishande zvakanaka uye kuvimbika kuri nani mumasisitimu aya. Kushandiswa kwayo musimba rinogona kushandiswazve kunobatsira kusimudzira kushanda kwepasi rose mukuchengetedza simba.

Kutaurirana nefoni:Iyo ingot yeSiC ine mainches matanhatu yakakodzerawo kugadzira zvinhu zvinoshandiswa muRF (radio frequency) ine simba guru. Izvi zvinosanganisira ma amplifiers, oscillators, uye mafirita anoshandiswa mumafoni uye masisitimu ekutaurirana nesatellite. Kugona kweSiC kubata ma frequency akakwira uye simba rakakwirira kunoita kuti ive chinhu chakanaka chemidziyo yekutaurirana inoda kushanda kwakasimba uye kurasikirwa kwemasaini kushoma.

Ndege neDziviriro:Simba guru reSiC rinoparara uye kuramba kupisa kwakanyanya kunoita kuti ive yakakodzera kushandiswa mundege nekudzivirira. Zvikamu zvakagadzirwa kubva kumaSiC ingots zvinoshandiswa mu radar systems, satellite communications, uye power electronics dzendege ne spacecraft. Zvinhu zvakagadzirwa neSiC zvinoita kuti spacecraft ishande zvakanaka mumamiriro ezvinhu akaipisisa anosangana nawo muchadenga nenzvimbo dzakakwirira.

Kuzvigadzira Kwemaindasitiri:Mukushanda kwemaindasitiri, zvikamu zveSiC zvinoshandiswa mumasensa, maactuator, uye masisitimu ekudzora anofanirwa kushanda munzvimbo dzakaoma. Zvishandiso zveSiC zvinoshandiswa mumichina inoda zvikamu zvinoshanda uye zvinogara kwenguva refu zvinokwanisa kutsungirira tembiricha yakakwira uye kumanikidzwa kwemagetsi.

Mhedziso

Iyo SiC Ingot ine mainch matanhatu – N-type Dummy/Prime grade chinhu chepamusoro-soro chinosangana nezvinodiwa zvakanyanya zveindasitiri yesemiconductor. Kupisa kwayo kwakanyanya, kusimba kwayo kwakanyanya, uye density yakaderera zvinoita kuti ive sarudzo yakanaka yekugadzira zvishandiso zvemagetsi zvine simba repamusoro, zvikamu zvemotokari, masisitimu ekutaurirana, uye masisitimu esimba rinodzokororwa. Ukobvu hwayo uye zvirevo zvakanyatsogadzirwa zvinoita kuti iyi SiC ingot ikwanise kugadziriswa kune akasiyana mashandisirwo, ichivimbisa kushanda kwepamusoro uye kuvimbika munzvimbo dzinoda kushanda zvakanyanya. Kuti uwane rumwe ruzivo kana kuisa odha, ndapota taura nechikwata chedu chekutengesa.
