Jean Hoerni

He invented the planar process, which is a manufacturing process used in the semiconductor industry to build individual components of a transistor, and connect those transistors together. He found that the key concept was to view a circuit in its two dimensional projection, thus allowing the use of photographic processing concepts such as film negatives to mask the projection of light exposed chemicals. Back then computers were really big and what scientists discovered after so many years is that more information fits on one chip now then it did then. my parents would never get a dino computer but now they are portable and easy to carry around.
