EARLY SEMICONDUCTOR DEVELOPMENT AT SHOCKLEY TRANSISTOR CORPORATION

Gene Weckler

Oral History – (Continued)

 

 

 

 

 

 

As an Applications Engineer at Shockley Transistor Corporation,  Gene was responsible for designing and building “demo units” to be used at trade shows and conventions to demonstrate the potential uses of the 4-layer diode technology.  The top photo shows a recent “Demonstrator Kit”, built for display at the TransistorMuseum.   Gene indicates that this audio oscillator, using a basic  “sawtooth circuit”, is similar to the style he used 45 years ago in his first job at Shockley.  The scan on the left is a section of one the patents issued to William Shockley for 4-layer (PNPN) diode applications.  This patent demonstrates the possible use of the diode as  the active element in a phone switching circuit.  Gene remembers building a demo unit for this application too. It was hoped by the company that this use of the diode would lead to orders for millions of the 4-layer diodes by Western Electric to replace the mechanical switches in use at the time.
