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.
