SOI yog dab tsi

SOI stands rau Silicon-On-Insulator, uas txhais tau tias silicon ntawm ib qho insulating substrate. Cov cuab yeej siv no qhia txog cov txheej faus oxide ntawm sab saum toj silicon thiab sab nraub qaum.
Taw qhia
Los ntawm kev tsim cov yeeb yaj kiab semiconductor ntawm cov khoom siv insulator, SOI cov khoom muaj qhov zoo uas cov silicon tsis tuaj yeem sib xws: nws tuaj yeem ua tiav dielectric kev sib cais ntawm cov khoom hauv kev sib xyaw ua ke thiab tshem tawm tag nrho cov kab mob parasitic latch hauv bulk silicon CMOS circuits; integrated circuits ua los ntawm cov khoom no kuj muaj qhov zoo xws li me me parasitic capacitance, siab integration ceev, ceev ceev, txheej txheem yooj yim, me me luv channel nyhuv, thiab tshwj xeeb tshaj yog haum rau low-voltage thiab low-power circuits. Yog li ntawd, nws tuaj yeem hais tau tias SOI yuav zoo li yuav dhau los ua cov thev naus laus zis tseem ceeb rau kev sib sib zog nqus submicron qis-voltage thiab qis-power integrated circuits. Tsis tas li ntawd, SOI cov ntaub ntawv kuj tseem siv los tsim MEMS optical keyboards, xws li siv cov tshuab micromachining ntau.
SOI txhais tau tias silicon transistor qauv ntawm insulator. Lub hauv paus ntsiab lus yog ntxiv cov khoom siv insulator ntawm Silicon transistors kom txo cov kab mob parasitic capacitance ntawm ob los ntawm ib nrab. Qhov kom zoo dua yog tias nws yooj yim dua los ua kom lub moos zaus thiab txo qis tam sim no los ua lub zog txuag hluav taws xob IC. Qee cov electrons uas yuav dhau los ntawm kev hloov pauv yuav raug pov tseg los ntawm kev khawb rau hauv silicon. SOI tiv thaiv kev poob ntawm electrons. Motorola hais tias CPU tuaj yeem ua kom lub moos nrawm los ntawm 20% thiab txo qis kev siv hluav taws xob los ntawm 30%. Tsis tas li ntawd, qee qhov teeb meem hluav taws xob tuaj yeem txo qis. Lwm lub ntsiab lus uas ntau tus neeg overclockers txaus siab rau yog tias nws qhov kev ua haujlwm kub tuaj yeem ncav cuag 300 degree, txo cov teeb meem overheating.
