May 7, First conceived as a monolithic integrated circuit in by Geoffrey Drummer.
December 1, Jean Hoerni concieves of a bipolar planar technology. Patent filed April 22, January 23, First planar IC with lithographically patterned metal interconnect described in Robert Noyce's notebook. September 27, Jay Last's group successfully yields an Integrated Circuit. You may like this also:. First Monolithic Silico Invented by Robert Noyce, Fairchild They produced the first planar integrated circuit, a 4 transistor, 5 resistor flip-flop in May All major semiconductor manufacturers licensed resulting Fairchild patents and converted their circuit design activities to the planar process that continues to underlie the billion transistor chips of today.
Fairchild and TI engaged in litigation over the patents for many years. Kilby and Noyce both received the National Medal of Science in and today are celebrated as co-inventors of the integrated circuit.
It was an idea whose time had come and the technology had developed to a point where it was viable. References to these papers and other resources are listed below. David A. Laws [AMD , V.

The earliest circuits were battery-powered, which made in a steady, constant current that always flowed in the same direction. This is direct current , or DC. The use of DC continued through the time of the first electric power systems. A major problem with the DC system was that power stations could serve an area of only about a square mile because of power loss in the wires.
In , engineers proposed harnessing the tremendous hydroelectric power potential of Niagara Falls to supply the needs of Buffalo, N. Although this power would ultimately go beyond Buffalo to New York City and even farther, there was an initial problem with distance. Buffalo was only 16 miles from Niagara Falls, but the idea was unworkable -- until Nikola Tesla made it possible, as we'll see on the next page.
