About Jean Hoerni
Jean Amédée Hoerni was a Swiss-born American engineer. He was a silicon transistor pioneer, and a member of the "traitorous eight". He developed the planar process, an important technology for reliably fabricating and manufacturing semiconductor devices, such as transistors and integrated circuits. The planar process was invented by Jean Hoerni, with his first patent filed in May 1959, while working at Fairchild Semiconductor. A few years later, Shockley recruited Hoerni to work with him at the newly founded Shockley Semiconductor Laboratory division of Beckman Instruments in Mountain View, California. In 1955 Carl Frosch and Lincoln Derrick discovered and patented surface passivation by silicon dioxide.
