Silicon Carbide (SiC) Substrate yeSiristaro Imwe Chete – 10×10mm Wafer Mufananidzo Wakaratidzwa

Tsananguro pfupi:

Iyo 10×10mm Silicon Carbide (SiC) single-crystal substrate wafer imhando yepamusoro-soro yakagadzirirwa kushandiswa mumagetsi emagetsi echizvarwa chinotevera uye mashandisirwo e optoelectronic. Iine thermal conductivity inoshamisa, bandgap yakafara, uye kugadzikana kwakanaka kwemakemikari, SiC substrates inopa hwaro hwezvishandiso zvinoshanda zvakanaka pasi pemamiriro ekupisa kwakanyanya, frequency yakakwira, uye voltage yakakwira. Idzi substrates dzakachekwa nemazvo kuita 10×10mm square chips, dzakanakira kutsvagisa, prototyping, uye kugadzirwa kwemidziyo.

Pfupiso yeSilicon Carbide (SiC) substrate wafer

IyoWafer yesimbi ine 10×10mm Silicon Carbide (SiC) imwe cheteimhando yepamusoro ye semiconductor yakagadzirwa kuti ishandiswe mumagetsi emagetsi echizvarwa chinotevera uye mashandisirwo e optoelectronic. Silicon Carbide (SiC) substrate wafer ine thermal conductivity yakanaka, gap yakafara, uye kugadzikana kwakanaka kwemakemikari, inopa hwaro hwezvishandiso zvinoshanda zvakanaka mumamiriro ekupisa kwakanyanya, mafrequency akakwira, uye voltage yakakwira. Izvi zvinogadziriswa nemazvo.Machipisi akaenzana ne10 × 10mm, yakakodzera kutsvagisa, kugadzira maprototype, uye kugadzira michina.

Nheyo yekugadzira Silicon Carbide (SiC) substrate wafer

Silicon Carbide (SiC) substrate wafer inogadzirwa kuburikidza nenzira dzePhysical Vapor Transport (PVT) kana sublimation growth. Maitiro acho anotanga ne high-purity SiC powder yakaiswa mu graphite crucible. Kana tembiricha yakanyanya ichipfuura 2,000°C uye nzvimbo yakadzorwa, upfu hunonyungudika kuita utsi uye hunoiswazve pa seed crystal yakanyatsorongeka, zvichiita ingot huru, isina kuremara.

Kana SiC boule yakura, inotanga:

Kucheka Ingot: Macheka ewaya edhaimani akagadzirwa nemazvo anocheka SiC ingot kuita mawafer kana machipisi.

Kukwesha nekukuya: Nzvimbo dzinoitwa kuti dzisakweshe kubvisa mavanga ejeko uye ukobvu hwakaenzana.

Kupukuta Kwemakemikari (CMP): Kunopedzisa girazi rakagadzirira epi rine kukwesha kwakanyanya pamusoro.

Kuisa doping yesarudzo: Kuisa doping yenitrogen, aruminiyamu, kana boron kunogona kuiswa kuti kugadzirise hunhu hwemagetsi (n-type kana p-type).

Kuongororwa kwemhando yepamusoro: Advanced metrology inoita kuti wafer isatsvedze, ukobvu hwayo hwakaenzana, uye defect density zvienderane nezvinodiwa zvakasimba zve semiconductor-grade.

Maitiro aya ane matanho akawanda anoita kuti pave nemachipisi esimbi e10×10mm Silicon Carbide (SiC) akasimba akagadzirira kukura kwe epitaxial kana kugadzirwa kwemidziyo zvakananga.

Hunhu hweSilicon Carbide (SiC) substrate wafer

Wafer yeSilicon Carbide (SiC) substrate inogadzirwa zvakanyanya ne4H-SiC or 6H-SiCmhando dzakasiyana-siyana:

4H-SiC:Iine maerekitironi akawanda anofamba, zvichiita kuti ive yakakodzera michina yemagetsi yakaita seMOSFETs uye Schottky diodes.
6H-SiC:Inopa hunhu hwakasiyana hweRF ne optoelectronic components.

Hunhu hukuru hweSilicon Carbide (SiC) substrate wafer:

Mukana wakakura:~3.26 eV (4H-SiC) - inogonesa voltage yakanyanya kukanganiswa uye kurasikirwa kweswitching kwakaderera.
Kufambisa kwekupisa:3–4.9 W/cm·K – inobvisa kupisa zvinobudirira, ichivimbisa kugadzikana mumasisitimu ane simba guru.
Kuoma:~9.2 pachikero cheMohs - inoita kuti michina igare kwenguva refu panguva yekugadzirisa uye kushanda kwemuchina.

Kushandiswa kweSilicon Carbide (SiC) substrate wafer

Kushandiswa kwakasiyana-siyana kweSilicon Carbide (SiC) substrate wafer kunoita kuti ive yakakosha mumaindasitiri akasiyana-siyana:

Magetsi Emagetsi: Hwaro hweMOSFET, IGBTs, uye Schottky diodes dzinoshandiswa mumotokari dzemagetsi (EVs), magetsi emumaindasitiri, uye ma inverters esimba rinogona kudzokororwa.

RF & Microwave Devices: Inotsigira ma transistors, ma amplifiers, uye zvikamu zve radar zve 5G, satellite, uye maapplication ekudzivirira.

Optoelectronics: Inoshandiswa mumaUV LED, maphotodetector, uye ma laser diodes uko kujeka kwakanyanya kweUV uye kugadzikana kwakakosha.

Mudenga neDziviriro: Nzvimbo yakavimbika yemagetsi anodziya zvakanyanya uye akaomarara nemwaranzi.

Masangano Ekutsvagisa neMayunivhesiti: Yakanakira zvidzidzo zvesainzi yezvinhu, kugadzira michina yemuenzaniso, uye kuyedza maitiro matsva e epitaxial.
