Bipolar device technology challenge and opportunity

Silicon bipolar device technologies provided 65% of the world's integrated circuits in 1983. Where low noise, high current, low or high voltage, high speed or low cost are required, bipolar technologies are used. This paper will review the present status of bipolar device technologies, which make possible 100-ps gate-propagation delays, 150-μm 2 gate areas, 1-GHz bandwidth amplifiers, on-chip control of over 1-A, 350-V operation, 14-GHz f T 's …
