sidiary RCA, which created some of the best power transistors ever made. The devel-
opment and manufacture of a low-cost, reliable silicon transistor paved the way for all
of today’s integrated circuits.
In the United States, the following semiconductor manufacturers make today’s dis-
crete, small-signal silicon BJTs:
Central Semiconductor
Crystalonics
Diodes, Inc.
Fairchild Semiconductor
Linear Integrated Systems
Microsemi
ON Semiconductor
Philips Semiconductors
Vishay
Zetex
