From Wired’s “This Day in Tech,” the invention of the IC, 1952:
The first integrated circuit was fairly crude — it had only a transistor and other components on a slice of germanium. But it did show the potential of the IC, which continues today to get smaller and more complex.
Just a few months later, Robert Noyce, one of the co-founders of Fairchild Semiconductor and Intel, solved some of the problems related to the interconnects, sharing the credit with Kilby for the practical IC.
Kilby patented the invention and won the 2000 Nobel Prize in Physics for his role in the creation of the IC.
