Ultra-Fast Silicon Bipolar Technology

Since the first bipolar transistor was investigated in 1947, enormous efforts have been devoted to semiconductor devices. The strong world­ wide competition in fabricating metal-oxide-semiconductor field-effect of develop­ transistor (MOSFET) memories has accelerated the pace ments in semiconductor technology. Bipolar transistors play a major role due to their high-speed performance. Delay times of about 20 ps per gate have already been achieved. Because of this rapid technologi­ cal progre...
