Jean Hoerni

Jean Hoerni was born September 26, 1924 in Switzerland. He was considered a pioneer of his time because, he invented the Planar process which is also know as the Micro Chip. The Planar process is a manufacturing process used to build individual components of transistors and connect them. It’s the basic process that is use to build integrated circuits. The Planar Process is a silicon-transistor manufacturing process with a fractional-micrometer-thick oxide layer that is grown on a silicon substrate

    Hoerni’s invention is still used toady. His invention made it so we can make computer smaller and less space consuming. But they still can hold just as much if not more information as older computer models. This discovery will most likely help us reduce computer size in the feature as well. With out Hoerni’s invention I would probably not be typing this very blog post right now in this class room with so many computer because they would still be to large and there wouldn’t be enough space to fit enough computers to have a full class.
