Saxena, Arjun N.

Biographical Notes

Arjun Nath Saxena was born in India and worked at the Indian Institute of Nuclear Physics. He received a Ph.D. degree in Physics from Stanford University and joined Fairchild circa 1960, initially reporting to David James, where he worked on epitaxial silicon growth techniques and later tunnel diodes. He moved to the Sprague Electric Company, located in North Adams, Massachusetts, circa 1965 and then went to RCA Labs, located in Princeton, New Jersey, both in semiconductor research roles. He retired as a professor in the Electrical, Computer, and Systems engineering Department at Rensselaer Polytechnic Institute in 1997. He served as the Consulting Editor of a book series on Microelectronics Manufacturing and has written the book “Invention of Integrated Circuits: Untold Important Facts.”
