1959

The 50's saw expanding use

of the PNP germanium transistors

Japan produced lower cost transistors

In 1959 Fairchild developed the Planar process

with a high quality NPN Silicon process

The better quality and lower cost

shut out Japan for quite some time

MOSFET transistor

Metal Oxide Ssemiconductor Field Effect Transistor

was an invention that changed the world.

A photo process, allowing integrated circuits

Computer chips

Solid state memory
