This building is the site of an international food and produce market. It is also the former location of the first semiconductor research and manufacturing company.
Historical marker sign says "Site of first silicon device and research manufacturing company in silicon valley. The research here led to the development of the silicon valley. 1956"
A plaque in the sidewalk says "Shockley Semiconductor Laboratory. This site, 391 South San Antonio Road, is the former location of the Shockley Semiconductory Laboratory. At this location in 1956, Dr. William Shockley started the first silicon device research and manufacturing company in the valley. The individuals that gathered to work at this site went on to form the pioneering Silicon Valley startup company, Fairchild Semiconductor Corporation, and invent the first practicable integrated circuit. The advanced research and ideas developed here led to the development of Silicon Valley and later breakthroughs in the computer industry."
