Jock, Quad, An excerpt from an article on the career of Robert Noyce, co-owner of the patent for the integrated circuit, has historical info to answer your questions: Kilby's circuits used tiny gold wires to connect the devices. In 1959, Hoerni's colleague, Robert Noyce, using Hoerni's planar process, eliminated the extrinsic metal wiring altogether by evaporating thin layers of metal that contacted the semiconductor elements through holes etched in the silicon dioxide. This was much more efficient than using wires that had to be painstakingly attached by hand. By 1962, integrated circuits were in volume production at Texas Instruments and Fairchild. Yields ramped up quickly and, by 1964, transistors that had cost five dollars in the 1950s cost about four cents. Integrated circuits were first used in hearing aids in 1963. By the mid-1960s, they were used extensively throughout the burgeoning electronics industry. Summarizing, volume production of transistors in the 50's, IC's in the 60's. So, if you include transistors, but no IC's yet, the semiconductor industry does go back 40+ years. FYI if interested, the whole article. chips.ibm.com Jock, you're much too late with the invention of the semiconductor (transistor) : The joint invention in 1947 of the transistor earned (John) Bardeen, with his associates William B. Shockley and Walter H. Brattain, the 1956 Nobel prize for physics. BUT WILL THIS MAKE LSI AND INTC GO UP? Tony
