, where he worked until retirement in 1981. His first assignment was to develop an electron multiplier to go with the Image Orthicon. This tube, which proved to be 100 times more sensitive than its predecessors, was used for the first 20 years of television broadcasting in the United States. In 1961, Weimer began making thin-film transistors in a coplanar process on

substrates. In a typical process, he would deposit a gold source and drain, then deposit polycrystalline semiconductor material, and place a gate on top. After he placed an insulator between the gate and semiconductor, he got excellent results, as published in his 1962 paper, "The TFT: A New Thin-Film Transistor", in the '' Proceedings of the IRE''. Weimer held over 90 patents, and was a member of the
