Semicera imayambitsa semiconductor yapamwamba kwambirisilicon carbide cantilever paddles, yopangidwa kuti ikwaniritse zofuna zokhwima za kupanga ma semiconductor amakono.
Thechitsulo cha silicon carbideimakhala ndi mapangidwe apamwamba omwe amachepetsa kufalikira kwa kutentha ndi kuwombana, ndikupangitsa kuti ikhale yodalirika kwambiri m'mikhalidwe yovuta kwambiri. Kumanga kwake kolimba kumapereka kukhazikika kokhazikika, kuchepetsa chiwopsezo cha kusweka kapena kuvala, zomwe ndizofunikira kwambiri pakusunga zokolola zambiri komanso kupanga kosasintha. Thebwato lamkatimapangidwe amaphatikizanso mosagwirizana ndi zida zopangira semiconductor, kuwonetsetsa kuti zimagwirizana komanso kugwiritsa ntchito mosavuta.
Chimodzi mwazinthu zodziwika bwino za SemiceraSiC palandi kukana kwake kwa mankhwala, komwe kumapangitsa kuti izichita bwino kwambiri m'malo omwe ali ndi mpweya wowononga komanso mankhwala. Kuyika kwa Semicera pakusintha mwamakonda kumalola mayankho ogwirizana.
