description Mohamed Atalla Overview
At Bell Labs, Mohamed Atalla helped solve problems at the surface of silicon that had hindered semiconductor devices. His work on surface passivation used an oxide layer to reduce unwanted effects at that boundary. Together with Dawon Kahng, he developed the MOSFET, a transistor in which an electric field controls current, providing an important basis for later digital circuit design. His contribution connects materials research to the development of microelectronics, rather than consisting only of a finished device.
Atalla is relevant to engineers studying early solid-state electronics and historians tracing the foundations of integrated circuits. The Computer History Museum explains the shared development of the MOS transistor.
