Sapphire dị ka ihe na-emepụta sekit semiconductor
Wafer sapphire dị gịrịgịrị bụ nke mbụ e ji ihe mkpuchi kpuchie ihe e tinyere silicon n'elu ya iji mepụta sekit agbakwunyere a na-akpọ silicon na sapphire (SOS). Na mgbakwunye na ihe mkpuchi eletriki ya dị mma, sapphire nwere nnukwu ike okpomọkụ. Iberibe CMOS na sapphire dabara adaba karịsịa maka ngwa redio dị ike (RF) dị ka ekwentị mkpanaaka, redio nchekwa ọha na eze na sistemụ nkwukọrịta satịlaịtị.
A na-ejikwa wafers sapphire kristal otu dị ka ihe ndị e ji eme ihe n'ụlọ ọrụ semiconductor maka ịkọpụta ngwaọrụ dabere na gallium nitride (GaN). Ojiji sapphire na-ebelata ọnụ ahịa nke ukwuu ebe ọ bụ ihe dị ka 1/7 nke ọnụ ahịa germanium. A na-ejikarị GaN na sapphire eme ihe na diode na-ewepụta ọkụ na-acha anụnụ anụnụ (LED).
Jiri dị ka ihe windo
A na-ejikarị sapphire sịntetik (nke a na-akpọ mgbe ụfọdụ iko sapphire) eme ihe dị ka ihe e ji achọ windo n'ihi na ọ na-enwu nke ọma n'etiti ogologo 150 nm (ultraviolet) na 5500 nm (infrared) nke ìhè (ọdịdị a na-ahụ anya dị site na ihe dị ka 380 nm ruo 750 nm) ma nwee nnukwu iguzogide nkụcha. Uru dị mkpa nke windo sapphire
