What types of work assignments did you perform and do you recall any of the Transitron employees you interacted with?

 

My job was to fix any real-time problems on the line. Improve process, increase yield, lower costs - no big breakthroughs, mainly evolutionary changes.  I interfaced mainly with production management and development. George Wells [9] , who I have maintained a long relationship with.  (Transitron, Fairchild, LSI Logic). Production control  - Bob Swanson CEO of Linear technology).  Engineers of other product lines, Jim Diller CEO of several Silicon Valley startups, John Royan CEO Cinergy 3, San Diego. Martin Ouderwald, John Van derAa, Equipment. Nick  de Woolf, Test equipment. (Later started Teradyne).

 

Transitron had probably peaked in 1960.  Grown junction was one of the major product lines, and was essentially obsolete. Fairchild had announced Planar technology, and even mesa tech was ahead of bar tech. The revenues at that time were around $100 million.  They made a range of devices, power transistors as well.  John Royan (John and I started another company) was involved in the power transistors.  He started in 1959.  Another source (for you) would be Pierre LeMond.  He was the top engineer.  I doubt whether they used the term “VP” at that time, but we was the chief technologist and all of engineering reported to him.  I doubt if Pierre was more than 27 at the time.

Most the guys were a generation or half a generation older than I was at the time.  So, I just happened to come in at the particular point in the industry where it was very easy for younger people to get senior jobs.  I knew, for example, Bob Noyce, and he was running Fairchild Semiconductor well before he was 30. 

 

 

The crystal technology at that time would be considered crude by today’s standards?

 

Oh yeahThe crystals, for example, looked like an onion, not all at what we think of as a crystal.  The actual crystal, as it came out of the crystal grower, was almost spherical. When you think of a (modern) silicon crystal, whatever the diameter, you think of a (cylinder) salami.  And what we used for the junctions was like a small tennis ball.  And really, the device was made in the materials dept.  By the time you had grown the crystal, you have really made the device, and all the slicing into the bars was simply mechanical.  You had no control of the device characteristics at that point – that was all determined.
