A semiconductor <physicist> who devised the <planar process> for manufacturing semiconductor devices. His patent uses an insulating surface coating while forming and protecting device junctions, making surface treatment part of reliable fabrication. This links the chemistry of a semiconductor surface to the repeatability and integration of electronic components.<Method of manufacturing semiconductor devices by Jean Hoerni>[Patent description and claims: coated wafer, junction formation and device protection]{ref}
