Tsanangudzo Pfupi

WeiTai Energy Technology Co., Ltd. mutengesi anotungamira anonyanya hunyanzvi mune wafer uye yepamusoro semiconductor yekushandisa.Isu takatsaurirwa kupa zvemhando yepamusoro, zvakavimbika, uye zvigadzirwa zvitsva kune semiconductor kugadzira, photovoltaic indasitiri uye mamwe ane hukama minda.

Mutsetse wedu wechigadzirwa unosanganisira SiC/TaC yakavharwa magirafu zvigadzirwa uye zvigadzirwa zveceramic, zvinosanganisira zvinhu zvakasiyana siyana sesilicon carbide, silicon nitride, uye aluminium oxide nezvimwe.

Parizvino, ndisu chete mugadziri kupa kuchena 99.9999% SiC coating uye 99.9% recrystallized nesilicon carbide.Iyo yakakura SiC yekupfeka kureba tinogona kuita 2640mm.
