Siegel patent notebook (#12)
Contains schematics and component parts lists for circuits designed to test and measure electrical parameters and reliability of the first NPN transistors produced by the company. Includes many tables of actual measurements recorded, including thermal resistance, power dissipation, breakdown voltages, leakage currents, etc., with pasted in tables, scope photos and graphs.
Murray Siegel was the first employee hired by Fairchild Semiconductor in 1957. He reported to co-founder Vic Grinich and headed the applications lab that planned and tested devices, including the first transistors and ICs. While awaiting the acquisition of their first building in 1957-10, Siegel and Grinich started work in the latter’s Palo Alto garage. Their first task was to build a workbench. Siegel told attendees at the Fairchild 50th reunion in 2007 that, “We had no idea how high it should be. So we stacked telephone books on a table in my motel room to the height of our belly buttons.” That became the standard Fairchild bench height and by extension the preferred height in semiconductor engineering labs across the valley. Before he left to join Jean Hoenri at Intersil circa 1968, Siegel was manager of Fairchild’s Industrial Applications department.
