IMMIGRANT OF THE DAY: MARTIN "JOHN" ATALLA - INVENTOR

Congrats to 2009 Inventors Hall of Fame inductee John Atalla, a native of Egypt. According to the Hall of Fame:

John Atalla is one of the inventors of the
metal-oxide-semiconductor field-effect transistor (MOSFET), the most
widely employed type of integrated circuit.


Born
in Port Said, Egypt, Atalla came to the United States for graduate
studies at Purdue University. After receiving his Ph.D. in 1949, he
joined Bell Laboratories to investigate the surface properties of
silicon semiconductors. By adopting a method of growing a layer of
silicon dioxide on top of a silicon wafer, Atalla was able to overcome
the surface states that prevented electricity from reaching the
semiconducting layer. This is known as surface passivation, a critical
step that made possible the ubiquity of silicon integrated circuits.


Atalla
then suggested that a field effect transistor - first envisioned in the
1920s and confirmed experimentally in the 1940s but not yet achieved --
be built of metal-oxide-silicon. Atalla assigned the task to Dawon
Kahng, a scientist in his group. Attalla and Kahng announced their
successful MOSFET at a 1960 conference.


In
addition to Bell Labs, Atalla also worked for Hewlett-Packard and
Fairchild Semiconductor. He later developed the data security system
that is used in most automated banking machines. He has founded several
companies, including Atalla Corp., A4 Systems, and TriStrata.
