Izifunda Ezihlanganisiwe

Isekethe edidiyelwe (IC) iyi-chip ye-semiconductor ethwala izinto eziningi ezincane njengama-capacitor, ama-diode, ama-transistors, nama-resistors.Lezi zingxenye ezincane zisetshenziselwa ukubala nokugcina idatha ngosizo lobuchwepheshe bedijithali noma be-analog.Ungacabanga nge-IC njenge-chip encane engasetshenziswa njengesifunda esiphelele, esithembekile.Amasekhethi ahlanganisiwe angaba ikhawunta, i-oscillator, i-amplifier, isango elinengqondo, isibali sikhathi, inkumbulo yekhompyutha, noma i-microprocessor.

I-IC ithathwa njengesakhiwo esiyisisekelo sazo zonke izinto zikagesi zanamuhla.Igama laso liphakamisa uhlelo lwezingxenye eziningi ezixhumene ezishumekwe kumpahla encane, eyenziwe nge-silicon-made semiconductor.

Umlando Weziyingi Ezihlanganisiwe 

Ubuchwepheshe besekethe edidiyelwe baqale bethulwa ngo-1950 nguRobert Noyce noJack Kilby e-United States of America.I-US Air Force yayingumthengi wokuqala walokhu kusungulwa okusha.UJack naye uKilby uqhubekile nokuwina uMklomelo KaNobel kuPhysics ngo-2000 ngokusungula kwakhe ama-ICs amancane.

Eminyakeni engu-1.5 ngemva kokwethulwa komklamo kaKilby, uRobert Noyce wethula inguqulo yakhe yesekethe ehlanganisiwe.Imodeli yakhe ixazulule izinkinga ezimbalwa ezisebenzayo kudivayisi kaKilby.UNoyce uphinde wasebenzisa i-silicon ekwenzeni imodeli yakhe, kuyilapho uJack Kilby esebenzisa i-germanium. 

URobert Noyce noJack Kilby bobabili bathole amalungelo obunikazi ase-US ngeqhaza labo kumasekethe ahlanganisiwe.Bazabalaza nezindaba zomthetho iminyaka eminingana.Ekugcineni, zombili izinkampani zika-Noyce kanye ne-Kilby zanquma ukweqa amalayisense eziqanjiwe futhi zikwethule emakethe enkulu yomhlaba wonke.

Izinhlobo Zesekhethi Ezihlanganisiwe

Kunezinhlobo ezimbili zamasekethe ahlanganisiwe.Lezi izi:

1. I-Analog ICs

I-Analog ICs inokukhiphayo okuguquguqukayo njalo, kuye ngesignali abayitholayo.Ngokombono, ama-IC anjalo angathola inani elingenamkhawulo lezifunda.Kulolu hlobo lwe-IC, izinga lokuphumayo lokunyakaza liwumsebenzi womugqa wezinga lokufakwayo lesiginali.

I-Linear ICs ingasebenza njengezikhulisi zerediyo-frequency (RF) kanye ne-audio-frequency (AF).I-amplifier yokusebenza (op-amp) iyidivayisi evame ukusetshenziswa lapha.Ngaphezu kwalokho, inzwa yokushisa ingenye isicelo esivamile.Ama-ICs olayini angavula futhi avale amadivayisi ahlukahlukene uma isignali isifinyelele inani elithile.Lobu buchwepheshe ungabuthola kumahhavini, kumahitha, nakuma-air conditioner. 

2. Ama-ICs edijithali 

Lezi zihlukile kuma-IC analogi.Azisebenzi phezu kwebanga elingaguquki lamazinga esignali.Kunalokho, asebenza kumazinga ambalwa asethwe ngaphambilini.Ama-ICs edijithali asebenza ngokuyisisekelo ngosizo lwamasango anengqondo.Amasango anengqondo asebenzisa idatha kanambambili.Amasignali kudatha kanambambili anamaleveli amabili kuphela aziwa ngokuthi aphansi (logic 0) kanye naphezulu (logic 1).

Ama-ICs edijithali asetshenziswa kuzinhlelo zokusebenza ezahlukahlukene njengamakhompyutha, amamodemu, njll.

Kungani Izifunda Ezihlanganisiwe Zidumile?

Yize yasungulwa cishe eminyakeni engama-30 edlule, amasekethe ahlanganisiwe asasetshenziswa ezinhlelweni eziningi.Ake sixoxe ngezinye zezinto ezinesibopho sokuduma kwazo : 

1.Ukuqina 

Eminyakeni embalwa edlule, imali engenayo yemboni ye-semiconductor yafinyelela ku-350 Billion USD emangalisayo.I-Intel yaba negalelo elikhulu lapha.Kwakukhona nabanye abadlali, futhi iningi lalaba bekungezamakethe yedijithali.Uma ubheka izinombolo, uzobona ukuthi amaphesenti angu-80 okuthengiswa okukhiqizwa imboni ye-semiconductor kwakuvela kule makethe.

Amasekethe adidiyelwe adlale indima enkulu kule mpumelelo.Uyabona, abacwaningi bemboni ye-semiconductor bahlaziye isekethe edidiyelwe, ukusetshenziswa kwayo, kanye nokucaciswa kwayo futhi bakukhuphula.

I-IC yokuqala eyake yasungulwa yayinama-transistors ambalwa nje - ama-5 ukuze acacise.Futhi manje sesiyibonile i-Intel's 18-core Xeon enama-transistors ayizigidi eziyizinkulungwane ezingama-5.5.Ngaphezu kwalokho, I-IBM's Storage Controller yayinama-transistors angu-7.1 billion anenqolobane engu-480 MB L4 ngo-2015.

Lokhu kukhula kudlale indima enkulu ekudumeni okukhona kwe-Integrated Circuits.

2. Izindleko

Kube nezinkulumo mpikiswano eziningana mayelana nezindleko ze-IC.Eminyakeni edlule, kube nokungaqondi kahle mayelana nenani langempela le-IC.Isizathu salokhu ukuthi ama-IC awasewona umqondo olula.Ubuchwepheshe buya phambili ngesivinini esimangalisayo, futhi abaklami bama-chip kufanele bahambisane nalesi sivinini lapho bebala izindleko ze-IC.

Eminyakeni embalwa edlule, ukubalwa kwezindleko ze-IC kwakusetshenziselwa ukuthembela ku-silicon die.Ngaleso sikhathi, ukulinganisa izindleko ze-chip kunganqunywa kalula ngosayizi wokufa.Nakuba i-silicon iseyingxenye eyinhloko ekubaleni kwabo, ochwepheshe badinga ukucabangela ezinye izingxenye lapho bebala izindleko ze-IC, futhi.

Kuze kube manje, ochwepheshe bathole isibalo esilula ukuze banqume izindleko zokugcina ze-IC:

Izindleko Zokugcina ze-IC = Izindleko Zephakheji + Izindleko Zokuhlola + Izindleko Zokufa + Izindleko Zokuthumela

Le zibalo ibheka zonke izakhi ezidingekayo ezidlala indima enkulu ekukhiqizeni i-chip.Ngaphezu kwalokho, kungase kube nezinye izici ezingase zicatshangelwe.Into ebaluleke kakhulu okufanele uyikhumbule lapho ulinganisela izindleko ze-IC ukuthi intengo ingahluka phakathi nenqubo yokukhiqiza ngezizathu eziningi.

Futhi, noma yiziphi izinqumo zobuchwepheshe ezithathwe phakathi nenqubo yokukhiqiza zingase zibe nomthelela omkhulu ezindlekweni zephrojekthi.

3. Ukwethembeka

Ukukhiqizwa kwamasekhethi ahlanganisiwe kuwumsebenzi obucayi kakhulu njengoba udinga ukuthi zonke izinhlelo zisebenze ngokuqhubekayo phakathi nezigidi zemijikelezo.Izinkambu zikagesi zangaphandle, amazinga okushisa aphakeme, nezinye izimo zokusebenza zonke zidlala indima ebalulekile ekusebenzeni kwe-IC.

Kodwa-ke, eziningi zalezi zinkinga ziqedwa ngokusetshenziswa kokuhlolwa kokucindezeleka okuphezulu okulawulwa kahle.Ayihlinzeki ngezindlela ezintsha zokuhluleka, okwandisa ukuthembeka kwamasekethe ahlanganisiwe.Singaphinda sinqume ukusatshalaliswa kokwehluleka ngesikhathi esifushane ngokusetshenziswa kokucindezeleka okuphezulu.

Zonke lezi zici zisiza ukuqinisekisa ukuthi isifunda esihlanganisiwe siyakwazi ukusebenza kahle.

Ngaphezu kwalokho, nazi ezinye izici zokunquma ukuziphatha kwamasekhethi ahlanganisiwe:
