Txoj Cai Tsim Khoom ntawm Silicon Carbide (SiC) substrate wafer

Cov wafer silicon carbide (SiC) substrate yog tsim los ntawm Physical Vapor Transport (PVT) lossis sublimation kev loj hlob. Cov txheej txheem pib nrog cov hmoov SiC siab-purity thauj mus rau hauv lub 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 ntawm cov noob siv lead ua tib zoo, tsim cov khoom siv lead ua loj, qhov tsis zoo-minimized ib leeg.

Thaum lub SiC boule loj hlob tuaj, nws yuav raug:

Kev txiav cov hlau nplaum: Cov hlau txiav pob zeb diamond precision txiav cov hlau nplaum SiC rau hauv cov wafers lossis cov chips.
