SEMICONDUCTOR
Waa maxay semiconductor?
Qalabka semiconductor waa qayb elektaroonik ah oo adeegsata korantada laakiin leh astaamo udhaxeeya kaareeyaha, tusaale ahaan naxaasta, iyo kan insulator-ka, sida galaaska. Qalabyadani waxay isticmaalaan korantada korantada ee xaalad adag oo ka soo horjeeda gobolka gaseous ama qiiqa kuleyliyaha ee vacuum, waxayna beddeleen tuubooyinka vacuum inta badan codsiyada casriga ah.
Isticmaalka ugu badan ee semiconductors waa chips wareegyada isku dhafan. Aaladahayada casriga ah ee xisaabinta, oo ay ku jiraan teleefanada gacanta iyo tablets-yada, waxa laga yaabaa inay ka koobnaan karaan balaayiin yar yar oo semiconductors oo ku xidhan hal chips oo dhamaantood ku xidhan hal wafer semiconductor ah.
Daawashada semiconductor waxaa lagu maamuli karaa dhowr siyaabood, sida in la soo bandhigo goob koronto ama birlab ah, iyadoo la soo bandhigayo iftiinka ama kulaylka, ama iyadoo ay ugu wacan tahay qallafsanaanta makaanikada ee silsiladda silikon monocrystalline doped. In kasta oo sharraxaadda farsamada ay aad u faahfaahsan tahay, wax-is-daba-marinta semiconductor-ka ayaa ah waxa suurtageliyay kacaankeenna dhijitaalka ah ee hadda.
SIDEE LOOGU ISTICMAALAA ALUUMUMANKA SEMICONDUCTORS?
Aluminiumku wuxuu leeyahay sifooyin badan oo ka dhigaya doorashada koowaad ee loo isticmaalo semiconductors iyo microchips. Tusaale ahaan, aluminiumku wuxuu leeyahay adhesion ka sarreeya silikoon dioxide, oo ah qayb weyn oo ka mid ah semiconductors (tani waa halka ay Silicon Valley magaceeda ka heshay). Waa sifooyin koronto, kuwaas oo ah in ay leedahay iska caabin koronto oo hooseeya oo ka dhigaysa xiriir aad u wanaagsan oo leh curaarta siliga, waa faa'iido kale oo aluminium ah. Waxa kale oo muhiim ah in ay fududahay in lagu qaabeeyo aluminium hababka qallalan ee etch, tallaabo muhiim ah oo samaynta semiconductors. Halka biraha kale, sida naxaasta iyo qalinka, ay bixiyaan iska caabbinta daxalka iyo adkaanta korantada, waxay sidoo kale aad uga qaalisan yihiin aluminium.
Mid ka mid ah codsiyada ugu caansan ee aluminium ee soo saarista semiconductors waa habka tignoolajiyada xajinta. Lakabyada khafiifka ah ee dhumucyada nano ee biraha nadiifsan ee sarreeya iyo silikoon ee marawaxadaha microprocessor-ka waxaa lagu dhammeeyaa hab socodka uumiga jirka ee loo yaqaan sputtering. Qalabka waxaa laga soo saaraa bartilmaameedka waxaana lagu shubaa lakabka substrate ee silikoon qolka faaruqinta kaas oo ka buuxsamay gaas si uu u fududeeyo habka; sida caadiga ah gaas aan shaqaynayn sida argon.
Taarikada dhabarka ee bartilmaameedyadan waxay ka samaysan yihiin aluminium oo leh walxo nadiif ah oo sarreeya, sida tantalum, copper, titanium, tungsten ama 99.9999% aluminium saafi ah, oo ku xidhan korkooda. Sawirka korontadu ama kiimikaad ee dusha sare ee substrate-ka ee korantada ayaa abuurta qaababka wareegga yar ee loo isticmaalo shaqada semiconductor.
Aluminium aluminiumka ugu caansan ee farsamaynta semiconductor waa 6061. Si loo hubiyo waxqabadka ugu fiican ee daawaha, guud ahaan lakabka anodized ilaalinta ayaa lagu dabaqi doonaa dusha sare ee birta, taas oo kor u qaadi doonta caabbinta daxalka.
Sababtoo ah waa aalado sax ah, daxalka iyo dhibaatooyinka kale waa in si dhow loola socdo. Dhowr arrimood ayaa la ogaaday inay gacan ka geystaan daxalka aaladaha semiconductor, tusaale ahaan ku baakadeynta balaastikada.
