Epitaxial Transistor Patent m The method of making the epitaxialtransistor and other improved semicon-ductor devices is the subject of a patentawarded recently to J. J. Kleimack, H. , and Dr. H. H. Loar of Bell Tele-phone Laboratories. The process, first an-nounced by Bell Labs in 1960, had immediateand widespread impact on the semiconductorindustry as it made possible transistors, di-odes and integrated circuits of improvedelectrical performance and low cost. It isconsidered one of the most important inven-tions in the field of solid-state electronicssince the original transistor was invented atBell
