Sapphire a matsayin substrate da'ira na semiconductor
Siraran sapphire wafers shine nasarar farko da aka yi amfani da wani abin rufe fuska wanda aka ajiye siliki akansa don ƙirƙirar da'irori masu haɗaka da ake kira silicon on sapphire (SOS).Baya ga kyawawan kaddarorinsa na rufe wutar lantarki, sapphire yana da haɓakar zafin jiki mai girma. CMOS kwakwalwan kwamfuta akan sapphire sun dace musamman don aikace-aikacen mitar rediyo mai ƙarfi (RF) kamar wayar hannu, radiyon kare lafiyar jama'a da tsarin sadarwar tauraron dan adam.
Hakanan ana amfani da wafer sapphire kristal guda ɗaya azaman maɓalli a cikin masana'antar semiconductor don haɓaka tushen gallium nitride (GaN).Yin amfani da sapphire yana rage yawan farashi yayin da yake kusan 1/7 na farashin germanium.GaN akan sapphire ana amfani dashi a cikin diodes masu haske mai haske (LEDs).
Yi amfani da azaman kayan taga
Sapphire na roba (wani lokaci ana kiransa gilashin sapphire) ana amfani dashi azaman kayan taga saboda yana da kyau sosai tsakanin 150 nm (ultraviolet) da 5500 nm (infrared) raƙuman haske na haske (bakan da ake iya gani daga kusan 380 nm zuwa 750 nm) kuma yana da matukar juriya ga karce.Babban fa'idodin windows sapphire
