Chithunzi cha SEMICONDUCTOR
KODI SEMICONDUCTOR NDI CHIYANI?
Chipangizo cha semiconductor ndi chigawo chamagetsi chomwe chimagwiritsa ntchito ma conduction amagetsi koma chimakhala ndi mawonekedwe omwe ali pakati pa cokondakita, mwachitsanzo mkuwa, ndi choteteza, monga galasi. Zipangizozi zimagwiritsa ntchito ma conduction a magetsi pamalo olimba kusiyana ndi mpweya wa mpweya kapena mpweya wa thermionic mu vacuum, ndipo m'malo mwa vacuum chubu mu ntchito zamakono.
Kugwiritsa ntchito kwambiri kwa semiconductors kumakhala mu tchipisi tating'onoting'ono. Zida zathu zamakono zamakompyuta, kuphatikiza mafoni am'manja ndi mapiritsi, zitha kukhala ndi mabiliyoni ang'onoang'ono a semiconductor omwe amalumikizidwa pa tchipisi tating'onoting'ono zonse zolumikizidwa pa chowotcha chimodzi cha semiconductor.
Ma conductivity a semiconductor amatha kusinthidwa m'njira zingapo, monga kuyambitsa mphamvu yamagetsi kapena maginito, poyatsa kuwala kapena kutentha, kapena chifukwa cha kusintha kwa makina a grid monocrystalline silicon. Ngakhale kufotokozera kwaukadaulo kuli mwatsatanetsatane, kusintha kwa ma semiconductors ndikomwe kwapangitsa kuti kusintha kwathu kwa digito kutheke.
KODI ALUMINIUM AMAGWIRITSA NTCHITO BWANJI MU MASEMICONDUCTOR?
Aluminiyamu ili ndi zinthu zambiri zomwe zimapangitsa kuti ikhale chisankho choyambirira chogwiritsidwa ntchito mu semiconductors ndi ma microchips. Mwachitsanzo, aluminiyamu imamatira kwambiri ku silicon dioxide, chigawo chachikulu cha semiconductors (apa ndipamene Silicon Valley idatcha dzina lake). Ndi mphamvu zamagetsi, kutanthauza kuti imakhala ndi mphamvu zochepa zamagetsi ndipo imapangitsa kulumikizana bwino ndi ma wire bond, ndi phindu lina la aluminiyumu. Chofunikanso ndikuti ndikosavuta kupanga aluminiyumu munjira zowuma, gawo lofunikira popanga ma semiconductors. Ngakhale zitsulo zina, monga mkuwa ndi siliva, zimapereka kukana bwino kwa dzimbiri komanso kulimba kwamagetsi, ndizokwera mtengo kwambiri kuposa aluminiyamu.
Chimodzi mwazinthu zofala kwambiri za aluminiyamu popanga ma semiconductors ndikugwiritsa ntchito ukadaulo wa sputtering. Kuyika kopyapyala kwa makulidwe a nano azitsulo zoyera kwambiri ndi silicon mu zowotcha zazing'onoting'ono zimakwaniritsidwa kudzera munjira yoyika nthunzi yomwe imadziwika kuti sputtering. Zinthu zimatulutsidwa kuchokera ku chandamale ndikuyikidwa pagawo la silicon mu chipinda cha vacuum chomwe chadzazidwa ndi mpweya kuti zithandizire njirayo; kawirikawiri mpweya wa inert monga argon.
Ma mbale othandizira pazolinga izi amapangidwa ndi aluminiyumu yokhala ndi zida zoyera kwambiri zoyikapo, monga tantalum, mkuwa, titaniyamu, tungsten kapena 99.9999% aluminiyamu yoyera, yolumikizidwa pamwamba pake. Photoelectric kapena chemical etching of the substrate conductive surface imapanga ma microscopic circuitry mapatani omwe amagwiritsidwa ntchito pa semiconductor.
Zomwe zimagwiritsidwa ntchito kwambiri ndi aluminiyamu mu processing semiconductor ndi 6061. Kuonetsetsa kuti aloyi ikugwira ntchito bwino, kawirikawiri chitetezo cha anodized chimagwiritsidwa ntchito pamwamba pa chitsulo, chomwe chidzalimbikitsa kukana kwa dzimbiri.
Chifukwa ndi zida zolondola, dzimbiri ndi zovuta zina ziyenera kuyang'aniridwa mosamala. Pali zinthu zingapo zomwe zapezeka zomwe zimapangitsa kuti zida za semiconductor ziwonongeke, mwachitsanzo kuziyika mu pulasitiki.
