Notes on Chapter 18: The Birth of Silicon Valley

Shockley Labs landmark – The site of Shockley Semiconductor Laboratory in Mountain View is commemorated today as a historical landmark [V-Shockley-Labs], [Leibson-1, 2018].

Fairchild Semiconductor landmark – The original Fairchild Semiconductor location in Palo Alto is also marked by a historical plaque recognizing its central role in the invention of the planar process and the integrated circuit [W-IC-Landmark1,2], [Leibson-2, 2018].

Noyce’s conceptualization of the integrated circuit – Noyce’s methodical approach to conceptualizing the integrated circuit drew on his deep understanding of both planar processing and circuit design. His reflections on this breakthrough are captured in [Berlin-1], [Reid], [O-Noyce].

Micrologic: first commercial integrated circuit – The completion and shipment of Fairchild’s Micrologic chip marked the first commercial delivery of a silicon-based integrated circuit, an event often seen as the true beginning of the IC industry [O-Micrologic].

Noyce and the Nobel Prize that might have been – When Gordon Moore attended the 2000 Nobel Prize ceremony in Stockholm, he did so partly in honor of Robert Noyce, who would have shared the prize for the integrated circuit had he lived [Reid].

Shockley’s four-layer diode – William Shockley’s attempt to commercialize his four-layer diode (also known as the Shockley diode) proved unsuccessful and became a cautionary tale of how leadership missteps can derail technical innovation [W-Shockley-Diode].

Noyce’s lost invention: the tunnel diode – Noyce independently invented a version of the tunnel diode but abandoned the work due to lack of support from Shockley [Berlin, 2005]. Years later, Leo Esaki won the Nobel Prize for this breakthrough as recounted in [Wood, 2011]. See also [W-Nobel-Esaki].

Lithography innovation at Fairchild– Inspired by the pioneering work of Jay Lathrop, Noyce recognized the potential of lithography for building integrated circuits. In a hands-on effort, he constructed an early lithography rig using camera lenses from a local photo shop, a key step that enabled the fabrication of Fairchild’s first planar transistors and integrated circuits [Miller, 2023].

Noyce’s innovation style and early accolades – Noyce was known for his exploratory, pragmatic style of innovation, echoing Picasso’s line, “I do not seek, I find.” He was also proud of having won the whimsical Brown Derby Prize during his Grinnell College years [Berlin-1].

Noyce’s predictions about the future – In various talks, Noyce forecast the coming era of portable phones, networked computers, and palm-sized televisions—remarkably prescient visions of today’s digital world [V-Noyce-1981].

Noyce’s management philosophy – At Fairchild, Noyce worked with HR leadership to articulate corporate values and principles, shaping a distinctive management culture that emphasized openness and innovation [Berlin-1].

The birth of the “Silicon Valley” name – Journalist Don Hoefler coined the term “Silicon Valley” in a 1971 series of articles in Electronic News, giving the region its now-famous moniker [Hoefler, 1971].

Noyce’s $500 startup capital– Lacking savings, Noyce borrowed $500 from his grandmother to invest as seed capital in Fairchild Semiconductor—a personal risk that paid historic dividends [Berlin-1].

IC sales driven by the space race– Demand for integrated circuits soared due to their critical role in space exploration, particularly in NASA’s Apollo guidance systems, which required compact, lightweight electronics [Berlin-1], [F-Silicon-Valley].

Noyce’s bold pricing move– At an industry conference, Noyce stunned the audience by announcing that Fairchild would sell integrated circuits for just one dollar each, anticipating dramatic cost reductions from future process improvements [Berlin-1], [Malone-1], [F-Silicon-Valley].

Fairchildren– The term “Fairchildren” refers to the family tree of companies founded by Fairchild alumni, a vast entrepreneurial network that seeded much of Silicon Valley’s growth [Laws, 2016] [Penn, 2021], [Penn, 2022a], [Penn, 2022b].
