SEMICONDUCTOR
MENENE SEMICONDUCTOR?
Na'urar semiconductor wani abu ne na lantarki wanda ke amfani da wutar lantarki amma yana da halayen da ke tsakanin na madugu, misali tagulla, da na insulator, kamar gilashi.Waɗannan na'urori suna amfani da wutar lantarki a cikin ƙaƙƙarfan yanayi sabanin yanayin iskar gas ko iskar zafi a cikin injin, kuma sun maye gurbin vacuum tubes a yawancin aikace-aikacen zamani.
Mafi yawan amfani da semiconductor shine a cikin guntuwar da'ira.Na'urorin lissafin mu na zamani, gami da wayoyin hannu da allunan, na iya ƙunsar biliyoyin ƙananan na'urori masu auna sigina waɗanda aka haɗa akan guntu guda ɗaya duk suna haɗin gwiwa akan wafer semiconductor guda ɗaya.
Za'a iya sarrafa aikin semiconductor ta hanyoyi da yawa, kamar ta hanyar gabatar da filin lantarki ko maganadisu, ta hanyar fallasa shi zuwa haske ko zafi, ko saboda nakasar injina na grid monocrystalline silicon grid.Yayin da bayanin fasaha ya cika daki-daki, magudin semiconductor shine abin da ya sanya juyin juya halin dijital na yanzu ya yiwu.
YA AKE AMFANI DA ALUMIUM A CIKIN SEMICONDUCTORS?
Aluminum yana da kaddarorin da yawa waɗanda suka sanya shi zaɓi na farko don amfani a cikin semiconductor da microchips.Misali, aluminum yana da mannewa mafi girma ga silicon dioxide, babban bangaren semiconductor (wannan shine inda Silicon Valley ya sami sunansa).Yana da kaddarorin lantarki, wato cewa yana da ƙarancin juriya na lantarki kuma yana yin kyakkyawar hulɗa da igiyoyin waya, wani fa'idar aluminum ne.Hakanan mahimmanci shine cewa yana da sauƙin tsara aluminum a cikin busassun matakan etch, muhimmin mataki na yin semiconductor.Yayin da sauran karafa, kamar jan karfe da azurfa, suna ba da mafi kyawun juriya na lalata da taurin wutar lantarki, su ma sun fi aluminum tsada.
Ɗaya daga cikin aikace-aikacen da aka fi sani da aluminum a cikin samar da semiconductor yana cikin aiwatar da fasahar sputtering.Nano kauri na nano kauri na tsaftataccen ƙarfe da silicon a cikin wafers na microprocessor ana yin su ta hanyar tsarin tsukewar tururi na zahiri wanda aka sani da sputtering.Ana fitar da kayan daga maƙasudi kuma an ajiye su a kan wani nau'in siliki na siliki a cikin ɗakin da aka cika da gas don taimakawa wajen sauƙaƙe hanya;yawanci iskar gas kamar argon.
Faranti na goyan bayan waɗannan makasudin an yi su ne da aluminum tare da manyan kayan tsabta don ajiya, kamar tantalum, jan ƙarfe, titanium, tungsten ko 99.9999% tsantsar aluminium, an haɗa su zuwa saman su.Photoelectric ko sinadarai etching na substrate's conductive surface yana haifar da ƙananan sifofi da ake amfani da su a cikin aikin semiconductor.
Mafi na kowa aluminum gami a semiconductor sarrafa shi ne 6061. Don tabbatar da mafi kyau yi na gami, gaba ɗaya wani m anodized Layer za a yi amfani da surface na karfe, wanda zai bunkasa lalata juriya.
Domin irin waɗannan na'urori masu mahimmanci, dole ne a sa ido sosai akan lalata da sauran matsalolin.An gano abubuwa da yawa don taimakawa ga lalata a cikin na'urorin semiconductor, misali tattara su cikin filastik.
