RCA had an established research capability and transistor manufacturing facility in place during the early years of the semiconductor industry. Its early microcircuit research-including Torkel Wallmark's work using the bipolar unijunction transistor in the late 1950s, Paul Weimer's thin-film transistor, and Steve Hofstein's metal-oxide silicon transistor-led to RCA's pioneering effort in the production of complementary (CMOS) silicon integrated circuits in the late 1960s and 1970s.
