ISapphire njenge-semiconductor circuit substrate

Iziphaluka zesafire ezibhityileyo yayilusetyenziso lokuqala oluyimpumelelo lwe-substrate ekhuselayo apho isilicon yafakwa khona ukwenza iisekethe ezidityanisiweyo ezibizwa ngokuba yisilicon kwisafire (SOS).Ukongeza kwizinto ezigqwesileyo zokugquma umbane, isafire ine-conductivity ephezulu ye-thermal conductivity.Iitshiphusi ze-CMOS kwisafire zifaneleke ngokukodwa usetyenziso lwerediyo olunamandla aphezulu (RF) njengeefowuni eziphathwayo, iirediyo zokhuseleko loluntu kunye neenkqubo zonxibelelwano ngesathelayithi.

Iziphaluka zesafire zekristale enye zikwasetyenziswa njengeesubstrates kushishino lwesemiconductor ukukhulisa izixhobo ezisekwe kwigallium nitride (GaN).Ukusetyenziswa kwesafire kunciphisa kakhulu iindleko njengoko malunga ne-1/7 yeendleko zegermanium.I-GaN kwi-sapphire isetyenziswa ngokuqhelekileyo kwi-blue light emitting diodes (LEDs).

Sebenzisa njengento yefestile

Isafire yokwenziwa (ngamanye amaxesha ibizwa ngokuba yiglasi yesafire) isoloko isetyenziswa njengesixhobo sefestile kuba icace kakhulu phakathi kwe-150 nm (i-ultraviolet) kunye ne-5500 nm (infrared) ubude bamaza okukhanya (i-spectrum ebonakalayo isuka malunga ne-380 nm ukuya kwi-750 nm) kwaye unokumelana okuphezulu kakhulu nokukrwempa.Iinzuzo eziphambili zeefestile zesafire

Bandakanya

I-bandwidth ye-optical transmission ebanzi kakhulu, ukusuka kwi-UV ukuya kwisibane esikufutshane ne-infrared

Yomelele kunezinye izinto ezibonakalayo okanye iifestile zeglasi

Ixhathisa kakhulu ekukrweleni kunye ne-abrasion (ubunzima beeminerali be-9 kwisikali se-Mohs, okwesibini kuphela kwidayimane kunye ne-moissanite phakathi kwezinto zendalo)

Indawo yokunyibilika ephezulu kakhulu (2030°C)
