The Semiconductor Special Interest Group (Semi SIG) comprises academic, industry, and professional volunteers who augment the work of the Computer History Museum staff in identifying, collecting, documenting, and exhibiting the impact of semiconductor technology on the history of computing.

Primitive semiconductor devices appeared in crystal radios in the early 1900s. The first transistor sprang into life in 1947 and the first monolithic integrated circuits were introduced in 1961. Fifty years later manufacturers were building devices with a billion transistors on a chip.

Semi SIG activities focus on collecting and preserving the stories and artifacts of this extraordinary era. Projects include recording oral histories of industry pioneers products and companies; collecting semiconductor devices and related documents and media; and raising funds to support the goals of the SIG.
