The first transistor was about half an inch high ... Instead of bothering with tiny wires, Brattain attached a single strip of gold foil over the point of a plastic triangle.

The researchers have shown that thousands of organic chemical transistors can be printed in a small area on thin plastic foil. Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy ...

This was the very first transistor ever made, built by Walter Brattain with the help of John Bardeen. It was made of two gold foil contacts sitting on a germanium crystal. Current coming in one ...
