Semicera's 4 Inch N-mhando SiC Substrates inogadzirwa kuti isangane neiyo chaiyo zviyero zveiyo semiconductor indasitiri. Aya ma substrates anopa hwaro hwekuita hwepamusoro hwehuwandu hwemashandisirwo emagetsi, achipa yakasarudzika conductivity uye zvinopisa zvivakwa.
Iyo N-type doping yeaya maSiC substrates anokwidziridza mabatiro adzo emagetsi, zvichiita kuti anyanyokodzera kune-high-power uye high-frequency application. Ichi chivakwa chinobvumira kushanda kwakanaka kwemidziyo yakadai sedhiodhi, transistors, uye amplifiers, uko kudzikisira kurasikirwa kwesimba kwakakosha.
Semicera inoshandisa mamiriro-e-the-art ekugadzira maitiro kuti ave nechokwadi chekuti imwe neimwe substrate inoratidza yakanakisa yemhando yepamusoro uye kufanana. Kurongeka uku kwakakosha pakushandisa mumagetsi emagetsi, microwave zvishandiso, uye humwe hunyanzvi hunoda kuita kwakavimbika pasi pemamiriro akanyanya.
Kubatanidza Semicera's N-mhando SiC substrates mumutsara wako wekugadzira zvinoreva kubatsirwa kubva kune zvinhu zvinopa epamusoro kupisa kupisa uye kugadzikana kwemagetsi. Aya ma substrates akanakira kugadzira zvinhu zvinoda kusimba uye kushanda zvakanaka, senge simba rekushandura masisitimu uye RF amplifiers.
Nekusarudza Semicera's 4 Inch N-mhando SiC Substrates, urikudyara mune chigadzirwa chinosanganisa hunyanzvi hwesainzi nehunyanzvi hwekuita. Semicera inoramba ichitungamira indasitiri nekupa zvigadziriso zvinotsigira kusimudzira kwekucheka-kumucheto semiconductor tekinoroji, kuve nechokwadi chekushanda kwepamusoro uye kuvimbika.
