Semicera's SOI Wafer (Silicon On Insulator) idapangidwa kuti ipereke kudzipatula kwamagetsi kwapamwamba komanso magwiridwe antchito amafuta. Kapangidwe kake kakang'ono kameneka, kokhala ndi silicon wosanjikiza pa insulating layer, kumapangitsa kuti chipangizocho chizigwira ntchito bwino komanso kuti chichepetse kugwiritsa ntchito mphamvu, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito zida zapamwamba zambiri.
Zowotcha zathu za SOI zimapereka phindu lapadera pamabwalo ophatikizika pochepetsa mphamvu ya parasitic ndikuwongolera liwiro la chipangizocho komanso kuchita bwino. Izi ndizofunikira kwambiri pamagetsi amakono, pomwe magwiridwe antchito apamwamba komanso mphamvu zamagetsi ndizofunikira kwa ogwiritsa ntchito komanso mafakitale.
Semicera imagwiritsa ntchito njira zopangira zapamwamba kuti apange zowotcha za SOI zokhazikika komanso zodalirika. Zophika izi zimapereka mpweya wabwino kwambiri wamafuta, zomwe zimawapangitsa kukhala oyenera kugwiritsidwa ntchito m'malo momwe kutentha kumadetsa nkhawa, monga pazida zamagetsi zolimba kwambiri komanso makina owongolera mphamvu.
Kugwiritsa ntchito zowotcha za SOI popanga semiconductor kumapangitsa kuti pakhale tchipisi tating'ono, mwachangu, komanso zodalirika. Kudzipereka kwa Semicera pakupanga uinjiniya wolondola kumawonetsetsa kuti zowotcha zathu za SOI zikukwaniritsa miyezo yapamwamba yofunikira paukadaulo wamakono m'magawo monga matelefoni, magalimoto, ndi zamagetsi zamagetsi.
Kusankha Semicera's SOI Wafer kumatanthauza kuyika ndalama muzinthu zomwe zimathandizira kupita patsogolo kwaukadaulo wamagetsi ndi ma microelectronic. Zophika zathu zidapangidwa kuti zizipereka magwiridwe antchito komanso kulimba, zomwe zimathandizira kuti mapulojekiti anu apamwamba apite patsogolo ndikuwonetsetsa kuti mumakhala patsogolo pazatsopano.
