Kev tsim cov qauv ntawm Silicon Carbide (SiC) substrate wafer

Silicon Carbide (SiC) substrate wafer yog tsim los ntawm Physical Vapor Transport (PVT) lossis sublimation txoj kev loj hlob. Cov txheej txheem pib nrog high-purity SiC hmoov loaded rau hauv graphite crucible. Nyob rau hauv qhov kub siab tshaj 2,000 ° C thiab ib puag ncig tswj, cov hmoov sublimates rau hauv vapor thiab rov tso rau hauv cov noob ua tib zoo taw qhia siv lead ua, tsim ib qho loj, tsis xws luag-tsawg ib qho siv lead ua ingot.

Thaum SiC boule loj hlob, nws nkag mus:

Ingot slicing: Precision pob zeb diamond hlau saws txiav SiC ingot rau hauv wafers lossis chips.

Lapping thiab sib tsoo: Nto yog flattened kom tshem tawm cov cim thiab ua tiav cov tuab tuab.

Chemical Mechanical Polishing (CMP): Ua tiav daim iav epi-npaj tiav nrog qhov tsis tshua muaj qhov roughness.

Kev xaiv doping: Nitrogen, txhuas, lossis boron doping tuaj yeem ua tswvcuab los kho cov khoom siv hluav taws xob (n-type lossis p-type).

Kev soj ntsuam zoo: Kev ntsuas qib siab ua kom wafer flatness, thickness uniformity, thiab qhov tsis xws luag raws li cov kev xav tau ntawm cov semiconductor-qib.

Cov txheej txheem ntau kauj ruam no ua rau muaj zog 10 × 10mm Silicon Carbide (SiC) substrate wafer chips uas tau npaj rau kev loj hlob ntawm epitaxial lossis kev tsim khoom ncaj qha.
