Frank Wanlass

from Wikipedia, the free encyclopedia

Frank Marion Wanlass (born May 17, 1933 in Thatcher , Arizona , † September 9, 2010 in Santa Clara , California ) was an American electrical engineer .

life and work

Wanlass grew up in Arizona and Utah and served in Army Intelligence during the Korean War. He received his PhD in physics from the University of Utah in 1962 with Henry Eyring and then went to Fairchild Semiconductor . In 1963 he invented CMOS technology there, for which he received a US patent in 1967. The technology led to significantly lower power consumption compared to bipolar transistors (six orders of magnitude less in its demonstration at the time, i.e. a million times) and formed the basis for the majority of later transistor applications in integrated circuits (initially in digital clocks ). In 1991 he received the Solid State Circuits Award for this .

He left Fairchild in 1964. He was then involved in various start- ups ( Four Phase , Zytrex , Standard Microsystems ). From 1970 he lived in California.

He was married in his first marriage since 1957 and had four children from this marriage.
