Peb tau sau ntau dua ib zaug tias cov khoom siv hluav taws xob tau dhau los ua "peb txhua yam." Cov khoom siv hluav taws xob txawb, hluav taws xob tsheb, Is Taws Nem ntawm cov khoom, lub zog cia thiab ntau ntxiv coj cov txheej txheem ntawm kev siv hluav taws xob thiab hluav taws xob hloov pauv mus rau thawj txoj haujlwm tseem ceeb hauv electronics. Technology rau zus tau tej cov chips thiab discrete hais siv cov ntaub ntawv xws li (GN). Nyob rau tib lub sijhawm, tsis muaj leej twg yuav tawm tsam qhov tseeb tias cov kev daws teeb meem sib xyaw ua ke zoo dua li kev sib cais ntawm ob qho tib si ntawm cov kev daws teeb meem thiab kev txuag nyiaj ntawm kev tsim thiab tsim khoom. Tsis ntev los no, ntawm PCIM 2019 lub rooj sib tham, cov kws tshawb fawb los ntawm Belgian center Imec kom meej meej uas ib leeg-chip fais fab mov (inverters) raws li GaN tsis yog science ntawv tseeb kiag li, tab sis qhov teeb meem ntawm lub neej yav tom ntej.
Siv gallium nitride ntawm silicon thev naus laus zis ntawm SOI (silicon ntawm insulator) wafers, Imec cov kws tshaj lij tau tsim ib qho kev hloov pauv ib nrab-chip. Qhov no yog ib qho ntawm peb txoj kev xaiv classic rau kev sib txuas hluav taws xob hloov hluav taws xob (transistors) los tsim hluav taws xob inverters. Feem ntau, los siv ib lub voj voog, ib txheej ntawm cov ntsiab lus sib cais yog coj. Yuav kom ua tiav ib qho kev sib cog lus, ib txheej ntawm cov ntsiab lus kuj tau muab tso rau hauv ib lub pob, uas tsis hloov qhov tseeb tias lub Circuit Court tau sib sau ua ke los ntawm ib tus neeg. Cov Belgians tau tswj kom rov tsim dua yuav luag tag nrho cov ntsiab lus ntawm ib nrab-choj ntawm ib qho siv lead ua: transistors, capacitors thiab resistors. Qhov kev daws teeb meem ua rau nws muaj peev xwm ua kom muaj txiaj ntsig ntawm kev hloov pauv hluav taws xob los ntawm kev txo cov kab mob parasitic uas feem ntau nrog kev hloov pauv hloov pauv.
Nyob rau hauv cov qauv qhia nyob rau hauv lub rooj sib tham, lub integrated GaN-IC nti hloov ib tug 48-volt input voltage mus rau ib tug 1-volt output voltage nrog ib tug hloov zaus ntawm 1 MHz. Cov kev daws teeb meem yuav zoo li kim heev, tshwj xeeb tshaj yog xav txog kev siv SOI wafers, tab sis cov kws tshawb fawb tau hais tias qhov kev sib koom ua ke siab ntau dua li offsets cov nqi. Kev tsim cov inverters los ntawm cov khoom sib cais yuav kim dua los ntawm kev txhais.
