Jean Hoerni

Since 1967 Jean has been the founder, President, and Chairman for the Board of Intersal. He received 2 Ph.D’s in his educational career. Most importantly he invented the Planar Process/Transistor. This provided the reliability needed for large system use. This device also allowed MOS devices more practical. It’s widely used for transistor fabrication. The oxide coating inherent in the structure of the planar transistor provided the necessary insulating film to enable the interconnection of the transistors in integrated circuits.
