Yintoni iSekethe eDityanisiweyo (IC)?

Ngaphambi kokufunyanwa kwe-ICs, indlela esisiseko yokwenza iisekethe yayikukukhetha amacandelo afana ne-diode, i-transistors, i-resistors, i-inductors kunye ne-capacitors kwaye idibanise ngokubambelela.Kodwa ngenxa yobungakanani kunye nemiba yokusetyenziswa kwamandla, kuye kwafuneka ukuba kuphuhliswe ubungakanani besekethe encinci kunye nokusetyenziswa kwamandla okuncinci, ukuthembeka kunye nokothuka.

Emva kokuveliswa kwee-semiconductors kunye nee-transistors, izinto zenziwe lula kwinqanaba elithile, kodwa uphuhliso lweesekethe ezidibeneyo zatshintsha ubuso betekhnoloji ye-elektroniki.UJack Kilby ovela eTexas Instruments kunye noBob Noyce ovela kwi-Intel ngabaqulunqi abasemthethweni beesekethe ezidibeneyo, kwaye bakwenza ngokuzimeleyo.

Isekethe edibeneyo yingqikelelo esisiseko ye-elektroniki eyakha kwezinye iikhonsepthi ezisisiseko ebekuxoxwe ngazo ngaphambili kwisilabhasi yethu.Ke ngoko, ngereferensi ekhawulezileyo, yiya kumanqaku adweliswe ngezantsi:
