Matambudziko aripo mukugadzirira kwe200mm 4H-SiC makristasi mainl

1) Kugadzirira kwemhando yepamusoro 200mm 4H-SiC makristasi embeu;

2) Saizi hombe tembiricha munda kwete-uniformity uye nucleation maitiro kudzora;

3) Kubudirira kwekufambisa uye kushanduka kwegasi zvikamu mukukura kwekristaro kukura masisitimu;

4) Crystal kupaza uye kuremara kuwanda kunokonzerwa nehukuru hukuru hwekupisa kushushikana kunowedzera.

Kukunda matambudziko aya uye kuwana mhando yepamusoro 200mm SiC waferssolutions inokurudzirwa:

Panyaya ye200mm yembeu yekristaro kugadzirira, yakakodzera tembiricha yekuyerera kwemunda, uye kuwedzera gungano zvakadzidzwa uye zvakagadzirirwa kufunga nezvemhando yekristaro nekukura kwekuwedzera; Kutanga ne 150mm SiC se: d crystal, ita mhodzi yekristaro iteration kuwedzera zvishoma nezvishoma SiC crystasize kusvika yasvika 200mm; Kuburikidza nekukura kwekristaro yakawanda uye processiig, zvishoma nezvishoma wedzera kunaka kwekristaro munzvimbo inokura yekristaro, uye kusimudzira mhando ye200mm mhodzi makristasi.

Panyaya ye200mm conductive crystal uye substrate kugadzirira, tsvakiridzo yakagadzirisa tembiricha feld uye kuyerera kwemunda dhizaini yekukura kukuru kwekristaro, kuitisa 200mm conductive SiC crystal kukura, uye kutonga doping kufanana. Mushure mekugadzirwa kwakashata uye kuumbwa kwekristaro, 8-inchelectricaly conductive 4H-SiC ingot ine dhayamita yakajairwa yakawanikwa. Mushure mekucheka, kukuya, kupukuta, kugadzirisa kuti uwane SiC 200mm wafers nehupamhi hwe525um kana zvakadaro.
