Jean Hoerni was born on September 26,1924. He was a famous inventor in Siwitzerland. He was known as the piorneer of his time fo his invention of the planar process. It is what now know as the micro chip. The planar manufacturing process is used to build the transitor and connect transitors together. It is the primary process that we use to build integrated circuits. It is a of growing an oxide layer on a silicon substrate. To create this layer you must complete a series of etching and diffusion steps is then used to produce the transistor.
His invention still is used today. His invention has helped make computers smaller, with more data space on a single chip. We have shrunken computers the size of a room down to the size we see today, and in the future smaller because of his process. With out his invention, most of us would never use a computer, because of inaccessibility.
