Later on, in the late 50’s,
there was a lot of circuit design for audio usage. We all built HiFi circuits with the RCA
transistors. So, from 1952 to 1956,
I was an engineer with the Advanced Development Group, working on small
signal transistors. After we
completed the work on transferring the TA153 from the labs to Harrison, I
worked on a variety of other transistors and diodes, such as the TA191,
TA132, TA203, SX150.
The Semiconductor Division was
formed in December, 1955. At that
point, we broke off from the Tube Division at Harrison, and RCA built a new semiconductor plant at
Somerville, NJ. I worked at this facility up until 1980, with a variety of
postions and assignments, including Engineering Leader, Senior Engineer,
and Senior Member of the Technical Staff.
At Somerville, we set up a
production facility as well as a semiconductor model shop. We were very busy and at some point in
the late 1950s, we were running three shifts a day. RCA then expanded the semiconductor
facilities by setting up a new manufacturing plant in Findlay, Ohio. This must have been in the 1960s. I spent quite a bit of time going out
there to assist in establishing the manufacturing lines. RCA continued to expand and opened up
another plant in Mountain Top, Pa.
Although I wasn’t much
involved with the opening of this
plant, I did spend a fair amount of time there from 1970 to 1975,
introducing new RF type transistors (CATV, UHF, VHF and low noise) into production.
