Silicon ya Silicon On Insulator (SOI) Wafer iri ku isonga mu guhanga udushya twa semiconductor, itanga amashanyarazi yiyongera kandi ikora neza. Imiterere ya SOI, igizwe na silicon yoroheje kurwego rwo hejuru, itanga inyungu zikomeye kubikoresho bya elegitoroniki bikora cyane.
Wafers yacu ya SOI yashizweho kugirango igabanye ubushobozi bwa parasitike nubushobozi bwo gutemba, ningirakamaro mugutezimbere umuvuduko mwinshi kandi ufite ingufu nkeya. Iri koranabuhanga ryateye imbere ryemeza ko ibikoresho bikora neza, hamwe n'umuvuduko wihuse kandi bikagabanya gukoresha ingufu, byingenzi kuri electronics zigezweho.
Ibikorwa byiterambere byateye imbere bikoreshwa na Semicera byemeza umusaruro wa SOI wafers hamwe nuburinganire buhebuje. Iyi miterere ningirakamaro mubisabwa mu itumanaho, mu modoka, no mu bikoresho bya elegitoroniki, aho bisabwa ibice byizewe kandi bikora neza.
Usibye inyungu zabo z'amashanyarazi, wafers ya SOI ya Semicera itanga ubushyuhe bwo hejuru bwumuriro, bikongerera ubushyuhe no gutuza mumashanyarazi menshi kandi afite ingufu nyinshi. Iyi mikorere ifite agaciro cyane mubikorwa birimo kubyara ubushyuhe bukomeye kandi bisaba gucunga neza ubushyuhe.
Muguhitamo Silicon ya Silicon Kuri Insulator Wafer, ushora mubicuruzwa bishyigikira iterambere ryikoranabuhanga rigezweho. Twiyemeje ubuziranenge no guhanga udushya twerekana ko wafers yacu ya SOI yujuje ibyifuzo bikenerwa ninganda zikoresha amashanyarazi muri iki gihe, bitanga umusingi wibikoresho bya elegitoroniki bizaza.
