SEMICONDUCTOR
SEMICONDUCTOR KE ENG?
Sesebelisoa sa semiconductor ke karolo ea elektronike e sebelisang tsamaiso ea motlakase empa e na le litšobotsi tse pakeng tsa conductor, mohlala koporo, le ea insulator, joalo ka khalase.Lisebelisoa tsena li sebelisa conduction ea motlakase sebakeng se tiileng ho fapana le sebakeng sa gaseous kapa thermionic emission in vacuum, 'me li nkile sebaka sa vacuum tubes lits'ebetsong tse ngata tsa sejoale-joale.
Tšebeliso e atileng haholo ea li-semiconductors ke li-chips tsa potoloho tse kopaneng.Lisebelisoa tsa rona tsa sejoale-joale tsa komporo, ho kenyeletsoa mehala ea thekeng le matlapa, li kanna tsa ba le libilione tsa li-semiconductors tse nyane tse kopantsoeng le li-chips tse le 'ngoe kaofela tse hokahantsoeng holim'a lesela le le leng la semiconductor.
The conductivity ea semiconductor e ka sebelisoa ka litsela tse 'maloa, tse kang ho hlahisa motlakase kapa matla a khoheli, ka ho o pepesetsa leseli kapa mocheso, kapa ka lebaka la ho senyeha ha mochine oa marang-rang a doped monocrystalline silicon.Le ha tlhaloso ea tekheniki e na le lintlha tse ngata, ho qhekella ha li-semiconductors ke hona ho entseng hore phetoho ea rona ea hajoale ea dijithale e khonehe.
ALUMINIUM E SEBELISA JOANG HO LI-SEMICONDUCTOR?
Aluminium e na le lisebelisoa tse ngata tse etsang hore e be khetho ea mantlha bakeng sa tšebeliso ea li-semiconductors le li-microchips.Mohlala, aluminium e na le mamaretso a phahameng ho silicon dioxide, karolo e kholo ea li-semiconductors (ke moo Silicon Valley e ileng ea reha lebitso la eona).Ke thepa ea motlakase, e leng hore e na le khanyetso e tlase ea motlakase 'me e etsa hore ho be le ho hokahana ho hoholo le libonto tsa terata, ke molemo o mong oa aluminium.Ho bohlokoa hape ke hore ho bonolo ho theha aluminium lits'ebetsong tse omeletseng, mohato oa bohlokoa oa ho etsa li-semiconductors.Le hoja litšepe tse ling, tse kang koporo le silevera, li fana ka khanyetso e ntle ea kutu le ho tiea ha motlakase, li boetse li theko e boima haholo ho feta aluminium.
E 'ngoe ea likopo tse atileng haholo tsa aluminium ha ho etsoa li-semiconductors ke ts'ebetsong ea theknoloji ea sputtering.Botenya ba nano ba litšepe tse hloekileng haholo le silicon ka har'a liphaephe tse nyane tsa microprocessor li finyelloa ka mokhoa oa ho beha mouoane oa 'mele o tsejoang ka hore ke sputtering.Lintho tse bonahalang li ntšoa ho sepheo ebe li kenngoa karolong e ka tlaase ea silicon ka kamoreng ea vacuum e tletseng khase ho thusa ho tsamaisa mokhoa ona;hangata khase ea inert joalo ka argon.
Lipoleiti tse tšehetsang lipakane tsena li entsoe ka aluminium e nang le lisebelisoa tse phahameng tsa bohloeki bakeng sa ho behoa, tse kang tantalum, koporo, titanium, tungsten kapa 99.9999% ea aluminium e hloekileng, e kopantsoeng holim'a eona.Motlakase oa lifoto kapa oa lik'hemik'hale sebakeng sa conductive sa substrate se theha mekhoa ea microscopic circuitry e sebelisoang mosebetsing oa semiconductor.
Ntho e tloaelehileng ka ho fetisisa ea aluminium alloy ka ho sebetsa ha semiconductor ke 6061. Ho etsa bonnete ba hore ts'ebetso e ntle ka ho fetisisa ea motsoako, ka kakaretso ho tla sebelisoa lera le sireletsang la anodized holim'a tšepe, e leng ho tla matlafatsa ho hanyetsa ha kutu.
Kaha ke lisebelisoa tse nepahetseng joalo, ho bola le mathata a mang li tlameha ho behoa leihlo ka hloko.Ho fumanoe lintlha tse 'maloa tse tlatsetsang ho bola ha lisebelisoa tsa semiconductor, mohlala ho li paka ka polasetiki.
