Sapphire e le semiconductor circuit substrate
Li-wafers tse tšesaane tsa safire e bile ts'ebeliso ea pele e atlehileng ea substrate e sireletsang moo silicon e ileng ea beoa ho etsa lipotoloho tse kopaneng tse bitsoang silicon on safire (SOS). Ho phaella ho thepa ea eona e babatsehang ea ho pata motlakase, safire e na le conductivity e phahameng ea mocheso. Li-chips tsa CMOS holim'a safire li loketse ka ho khetheha bakeng sa lisebelisoa tsa maqhubu a seea-le-moea (RF) a matla a phahameng a kang lithelefono tsa thelefono, li-radio tsa sechaba tsa tšireletso ea sechaba le mekhoa ea puisano ea sathelaete.
Li-wafers tse le 'ngoe tsa kristale sapphire li boetse li sebelisoa e le li-substrates indastering ea semiconductor bakeng sa lisebelisoa tse thehiloeng ho gallium nitride (GaN). Tšebeliso ea safire e fokotsa litšenyehelo haholo kaha e ka ba 1/7th theko ea germanium.GaN holim'a safire hangata e sebelisoa ka blue light emitting diodes (LEDs).
Sebelisa e le thepa ea fensetere
Synthetic sapphire (eo ka linako tse ling e bitsoang khalase ea safire) hangata e sebelisoa e le thepa ea lifensetere hobane e pepenene haholo lipakeng tsa 150 nm (ultraviolet) le 5500 nm (infrared) wavelengths ea khanya (maqhubu a bonahalang a tloha ho 380 nm ho isa ho 750 nm) mme e na le khanyetso e phahameng haholo ea scra.
