Background
Atalla was born in Portuguese Said, Egypt.
Atalla was born in Portuguese Said, Egypt.
He studied at Cairo University in Egypt, where he received his Bachelor of Science degree. There he received, in 1947, his master"s degree (Master of Science in Mechanical Engineering and in 1949, his doctorate.
In recognition of his work for the Personal Identification Number System (PIN) system of information security management system, he is also referred to as the "Father of the PIN". He has been inducted in the National Inventors Hall of Fame in 2009 for his contribution towards semiconductor technology. He went to the United States of America to study mechanical engineering at Purdue University.
After his studies, Atalla was employed at Bell Laboratories.
He researched among other things, the use of silica as a protective layer of silicon semiconductor devices. 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 assigned the task to Dawon Kahng, a scientist in his group.
Attalla and Kahng announced their successful Metal–oxide–semiconductor field-effect transistor at a 1960 conference.
Their research led to the development of the first metal oxide semiconductor field effect transistor (Metal–oxide–semiconductor field-effect transistor). The Metal–oxide–semiconductor field-effect transistor has evolved since the central component of today"s integrated circuits such as microprocessors and semiconductor memory. In 1961, Atalla co-founded Hewlett-Packard and Associates, which provided Hewlett Packard with fundamental solid-state capabilities, and went on to help create Himachal Pradesh Labs, directing its solid-state division.
In 1969, he went to Fairchild Semiconductor.
In 1973, he founded the that dealt with safety problems of the banking and financial institutions. He invented the so-called "Atalla Box", a security system that secures a majority of transactions from ATMs today.
At this time, also Atalla invented the PIN system that has developed among others in the banking industry as the standard for identification. 1987 merged with Tandem Computers.
Atalla went into retirement in 1990.
But it was not long until several executives of large banks persuaded him to develop security systems for the internet to work. They were worried about the fact that no useful framework for electronic commerce would have been possible at that time without innovation in the computer and network security industry. As a result of these activities, he founded the company TriStrata (1996) and A4 system.
M. Atalla was (2003) the chairman of A4 system and Lived in Atherton, California.
Atalla died on December 30, 2009 in Atherton.
