Semicera's 8 Inch N-type SiC Wafers ali patsogolo pa luso la semiconductor, akupereka maziko olimba a chitukuko cha zipangizo zamakono zamakono. Ma wafer awa adapangidwa kuti akwaniritse zofunikira zamagetsi amakono, kuyambira pamagetsi amagetsi mpaka mabwalo othamanga kwambiri.
Ma doping amtundu wa N mu zowotcha za SiC izi zimakulitsa mphamvu yamagetsi, kuwapangitsa kukhala abwino kwa ntchito zosiyanasiyana, kuphatikiza ma diode amagetsi, ma transistors, ndi amplifiers. Kuwongolera kwapamwamba kumatsimikizira kutayika kwa mphamvu zochepa komanso kugwira ntchito moyenera, zomwe ndizofunikira kwambiri pazida zomwe zimagwira ntchito pafupipafupi komanso mphamvu zamagetsi.
Semicera imagwiritsa ntchito njira zopangira zapamwamba kuti apange zowotcha za SiC zokhala ndi mawonekedwe apamwamba komanso zolakwika zochepa. Mlingo wolondolawu ndi wofunikira pamapulogalamu omwe amafunikira magwiridwe antchito komanso kulimba, monga mafakitale apamlengalenga, magalimoto, ndi matelefoni.
Kuphatikizira Semicera's 8 Inch N-type SiC Wafers mumzere wanu wopanga kumapereka maziko opangira zida zomwe zimatha kupirira malo ovuta komanso kutentha kwambiri. Zophika izi ndizoyenera kugwiritsa ntchito kutembenuza mphamvu, ukadaulo wa RF, ndi magawo ena ofunikira.
Kusankha Semicera's 8 Inch N-type SiC Wafers kumatanthauza kuyika ndalama muzinthu zomwe zimaphatikiza sayansi yapamwamba kwambiri ndi uinjiniya wolondola. Semicera yadzipereka kupititsa patsogolo luso la matekinoloje a semiconductor, ndikupereka mayankho omwe amathandizira kuti zida zanu zamagetsi zikhale zogwira mtima komanso zodalirika.
