His work at HP and Fairchild included research on Schottky diode, gallium arsenide (GaAs), gallium arsenide phosphide (GaAsP), indium arsenide (InAs) and light-emitting diode (LED) technologies.

His invention of the MOSFET was initially overlooked at Bell, which led to his resignation from Bell and joining Hewlett-Packard (HP), founding its Semiconductor Lab in 1962 and then HP Labs in 1966, before leaving to join Fairchild Semiconductor, founding its Microwave & Optoelectronics division in 1969. It is also the most widely manufactured device in history, and the US Patent and Trademark Office calls it a 'groundbreaking invention that transformed life and culture around the world'. The MOSFET in particular is the basic building block of modern electronics, and is considered one of the most important inventions in electronics. Atalla's pioneering work at Bell contributed to modern electronics, the silicon revolution, and Digital Revolution. He made several important contributions to semiconductor technology at Bell, including his development of the surface passivation and thermal oxidation processes (the basis for silicon semiconductor technology such as the planar process and monolithic integrated circuit chips), his invention of the MOSFET with Kahng in 1959, and the PMOS and NMOS fabrication processes.

He received the Stuart Ballantine Medal (now the Benjamin Franklin Medal in physics) and was inducted into the National Inventors Hall of Fame for his important contributions to semiconductor technology as well as data security.īorn in Port Said, Egypt, he was educated at Cairo University in Egypt and then Purdue University in the United States, before joining Bell Labs in 1949 and later adopting the more anglicized ' John' or ' Martin' M. He is also known as the founder of the data security company Atalla Corporation (now Utimaco Atalla), founded in 1972. He is best known for inventing the MOSFET (metal–oxide–semiconductor field-effect transistor, or MOS transistor) in 1959 (along with his colleague Dawon Kahng), which along with Atalla's earlier surface passivation and thermal oxidation processes, revolutionized the electronics industry. He was a semiconductor pioneer who made important contributions to modern electronics.

Atalla ( Arabic: محمد عطاالله Aug– December 30, 2009) was an Egyptian-American engineer, physicist, cryptographer, inventor and entrepreneur.
