Microelectronic silicon computer “chips” have grown in capability from a single transistor in the 1950s to hundreds of millions of transistors per chip on today’s microprocessor and memory devices. From the first documented semiconductor effect in 1833 to the transition from transistors to integrated circuits in the 1960s and 70s, this website explores key milestones in the development of these extraordinary engines that power the computing and communications revolution of the information age.
