They laid very thin paths of metal (usually aluminum or copper) directly on the same piece of material as their devices. In 1958 Jack Kilby of Texas Instruments, Inc., and Robert Noyce of Fairchild Semiconductor Corporation independently thought of a way to reduce circuit size further. Know the functioning of the ICL 2966 an integrated circuit mainframe computer See all videos for this article Now that electrical devices could be made so small, the largest part of a circuit was the awkward wiring between the devices. Using the same principles and materials, engineers soon learned to create other electrical components, such as resistors and capacitors. Solid-state devices proved to be much sturdier, easier to work with, more reliable, much smaller, and less expensive than vacuum tubes. The study of methods of creating electronic devices using solid materials became known as solid-state electronics. They named this device a transistor, from a combination of the words transfer and resistor. Controlling electron flow through a crystal allowed the team to create a device that could perform certain electrical operations, such as signal amplification, that were previously done by vacuum tubes. Brattain) found that, under the right circumstances, electrons would form a barrier at the surface of certain crystals, and they learned to control the flow of electricity through the crystal by manipulating this barrier. Shockley’s team (including John Bardeen and Walter H. Shockley and his team at the American Telephone and Telegraph Company’s Bell Laboratories. Integrated circuits have their origin in the invention of the transistor in 1947 by William B.
