ABSTRACT
The development of a bipolar technology for integrated circuits goes hand in hand with the steady improvement in semiconductor materials and discrete components during the 1950s and 1960s. Consequently, silicon bipolar technology formed the basis for the IC market during the 1970s. As circuit dimensions shrink, the MOSFET (or MOS) has gradually taken over as the major technological platform for silicon integrated circuits. The main reasons are the ease of miniaturization and high yield for MOS compared to bipolar technology. However, during the same period of MOS growth, much progress was
simultaneously achieved in bipolar technology.
