When Is a Microprocessor Not a Microprocessor? the Industrial Construction of Semiconductor Innovation I
Ross Bassett When is a Microprocessor not a Microprocessor? The Industrial Construction of Semiconductor Innovation I In the early 1990s an integrated circuit first made in 1969 and thus ante dating by two years the chip typically seen as the first microprocessor (Intel's 4004), became a microprocessor for the first time. The stimulus for this piece ofindustrial alchemy was a patent fight. A microprocessor patent had been issued to Texas Instruments, and companies faced with patent infringement lawsuits were looking for prior art with which to challenge it. 2 This old integrated circuit, but new microprocessor, was the ALl, designed by Lee Boysel and used in computers built by his start-up, Four-Phase Systems, established in 1968. In its 1990s reincarnation a demonstration system was built showing that the ALI could have oper ated according to the classic microprocessor model, with ROM (Read Only Memory), RAM (Random Access Memory), and I/O (Input/ Output) forming a basic computer. The operative words here are could have, for it was never used in that configuration during its normal life time. Instead it was used as one-third of a 24-bit CPU (Central Processing Unit) for a series ofcomputers built by Four-Phase.3 Examining the ALl through the lenses of the history of technology and business history puts Intel's microprocessor work into a different per spective. The differences between Four-Phase's and Intel's work were industrially constructed; they owed much to the different industries each saw itselfin.4 While putting a substantial part ofa central processing unit on a chip was not a discrete invention for Four-Phase or the computer industry, it was in the semiconductor industry. -

pter O ha n C e An Historic Overview of Venture Capitalism • Those who cannot remember the past are condemned to repeat it. —George Santayana Why is an historical overview of VC important? Because history does in fact repeat itself, and a study of history allows us to frame an understanding of the present and the future. The playersCOPYRIGHTED and the investment climate MATERIAL change, but the entrepreneur’s innate instinct to risk capital for a return is no different today from what it was when John D. Rockefeller became America’s first billionaire in 1900. When Andrew c01.indd 1 10-12-2013 8:50:11 [2] The Little Book of Venture Capital Investing Carnegie joined forces with his childhood friend, Henry Phipps, to form Carnegie Steel in 1892, they were driven by the same conviction to improve the status quo as are the idealistic dream chasers of the twenty-first century. It was these early trailblazers who paved the way and developed the techniques that have laid the foundation for VC as we know it today. Arguably, historians will debate the nature of history and its usefulness. This includes using the discipline as a way of providing perspective on the problems and opportu- nities of the present. I believe it to be an important tool in providing a systematic account and window to the future. It is patently dishonest and irresponsible to perpetuate the popular mythology that those who created great wealth in America are to be despised and that there are no useful les- sons to be learned from an objective, historical review of their contributions to the subject at hand. -

Stanford Law Review
Stanford Law Review Volume 70 April 2018 NOTE Beyond Covenants Not to Compete: Equilibrium in High-Tech Startup Labor Markets Yifat Aran* Abstract. The literature analyzing the relationship between enforceability of covenants not to compete and the success of Silicon Valley is incomplete. The microstructure of the employee stock options market, combined with California’s strong public policy against noncompete enforcement, creates an equilibrium in which employees at less succesful firms can move to competitors at little or no cost, but valuable employees of successful private firms are, practically, handcuffed just as if they were subject to a powerful noncompete. This limitation on employee mobility is removed once the company holds a liquidity event—such as an initial public offering or acquisition—allowing its entrepreneurial talent to transition to other companies or start new ones. This Note argues that this narrowly tailored retention function provides a more compelling explanation for Silicon Valley’s success than does an explanation that has become popular among policymakers in recent years: the unenforceability of noncompetes as the sole factor. This Note further suggests that companies’ current tendency to delay liquidity events, a tendency facilitated by recent changes in the private capital market and the securities regulatory environment, might overly restrict employee mobility and impair the efficient allocation of talent that characterized Silicon Valley for many years. * J.S.D.

A Network Analysis of the SEMI Genealogy Chart (1947–1986)
Int. J. Technology Management, Vol. 25, Nos. 1/2, 2003 181 The semiconductor community in the Silicon Valley: a network analysis of the SEMI genealogy chart (1947–1986) Dimitris Assimakopoulos ESC-Grenoble, 12 Rue Pierre Semard, Grenoble 38003, France E-mail: [email protected] Sean Everton and Kiyoteru Tsutsui Department of Sociology, Stanford University, Stanford, California 94305-2047, USA Abstract: This paper focuses on the emergence of an informal, collaborative and entrepreneurial organisational culture within the technological community of semiconductor firms in the Silicon Valley, California. Using recently developed computerised network analysis techniques and a genealogy chart of Silicon Valley semiconductor firms, it demonstrates how a new democratic community, rather than a hierarchical workplace, organisational culture was firstly initiated with the foundation of Fairchild Semiconductor back in 1957, and more importantly, how this new culture was diffused through successive generations of ‘Fairchildren’ spin-offs, up to the mid-1980s. In the process of critical mass formation they also identified the most central companies in the semiconductor community, including the usual suspects, Fairchild, Intel and Hewlett-Packard, but also a relatively unknown firm outside the semiconductor community, Intersil Co. Keywords: Silicon Valley; semiconductor industry; network analysis; Fairchild Semiconductor. Reference to this paper should be made as follows: Assimakopoulos, D., Everton, S. and Tsutsui, K.
