Cov teeb meem tam sim no hauv kev npaj ntawm 200mm 4H-SiC crystals mainl

1) Kev npaj cov khoom zoo 200mm 4H-SiC noob muaju;

2) Qhov loj qhov kub thiab txias teb tsis sib xws thiab cov txheej txheem nucleation tswj;

3) Kev thauj mus los thiab kev hloov pauv ntawm cov khoom siv roj av hauv kev loj hlob siv lead ua loj;

4) Crystal cracking thiab defect proliferation tshwm sim los ntawm loj loj thermal kev nyuaj siab nce.

Txhawm rau kov yeej cov kev cov nyom no thiab tau txais txiaj ntsig zoo 200mm SiC waferssolutions tau thov:

Nyob rau hauv cov nqe lus ntawm 200mm noob siv lead ua npaj, qhov tsim nyog qhov kub thiab txias fieldflow, thiab expanding los ua ke tau kawm thiab tsim los coj mus rau hauv tus account siv lead ua zoo thiab expanding loj;Pib nrog 150mm SiC se:d siv lead ua, nqa cov noob siv lead ua iteration kom maj mam nthuav SiC crystalsize kom txog thaum nws ncav cuag 200mm;Los ntawm ntau yam siv lead ua kev loj hlob thiab processiig, maj mam txhim kho cov siv lead ua zoo hauv thaj chaw siv lead ua nthuav dav, thiab txhim kho qhov zoo ntawm 200mm noob muaju.

Nyob rau hauv cov nqe lus ntawm 200mm conductive siv lead ua thiab substrate npaj, kev tshawb fawb tau optimized lub kub feld thiab ntws teb tsim rau loj loj crystalgrowth, ua 200mm conductive SiC siv lead ua kev loj hlob, thiab tswj doping uniformity.Tom qab kev ua haujlwm ntxhib thiab ua kom zoo ntawm cov siv lead ua, tau txais 8-inchelectricaly conductive 4H-SiC ingot nrog tus qauv kab.Tom qab txiav, sib tsoo, polishing, ua kom tau SiC 200mm wafers nrog lub thickness ntawm 525um los yog li ntawd
