The Silicon Engine: A Timeline of Semiconductors in Computers website has been developed by the Semiconductor Special Interest Group (Semi SIG) and the curatorial and technology staffs of the Computer History Museum, Mountain View, California, supported by a grant from the Gordon and Betty Moore Foundation. Key contributors are acknowledged on the Credits page under the Resources tab. The site describes the major milestones in the development of semiconductor technology that enabled the computing and communications revolution of the second half of the twentieth century.

The Timeline pages cover the period from the first documented semiconductor effect in 1833 to the completion of the transition from discrete transistors to integrated circuits, marked by the development of the single-chip digital signal processor in 1979, in the format of successive technological milestone events. Each page describes a specific event, identified as the milestone, and places it in the context of prior developments that led up to it and future events derived from it. The People, Companies, and Glossary pages provide more details on each of these topics than can be included in the space available for the Timeline text.

While significant advances in speed, complexity and cost have been made since 1979, the period covered by the website embraces the development of the fundamental technologies and building blocks employed in today’s billion-transistor microelectronic chips. The content describes the people, products, and processes that made a difference in computing systems. It does not attempt to describe how semiconductors work nor does it cover the myriad companies, products, and technologies created to serve other applications.

As in every creative endeavor, individual contributors to technology are typically the catalyst for progress and those accorded the highest acclaim. Whenever possible, we have identified the supporting team members who played critical roles and without whom many breakthroughs could not have happened. We have also tried to show how most inventions in the field of high technology are built on the foundation of ideas and the efforts of legions of earlier contributors. As a result, when technology advances to the point that they are practical such developments often occur contemporaneously in laboratories around the world. We include several such parallel developments. Our focus on computing systems does not allow us to cover significant work in Europe and Japan in consumer applications beyond a couple of early examples. Also our time span does not extend to the mid-1980s and beyond when Japanese, Korean, and Chinese manufacturers began to assume their current important roles.

Each milestone includes references to key Original Documents and More Information in the form of selected articles, books, papers, and patents that provide historical insight into the topic. Some of these are available online - use a search engine to track them down. Most are available in specialized technical libraries or via on-line subscription services. The following sections listed on this Resource page include some more general semiconductor history books, plus links to oral history resources and to selected websites.
