Abstract :
The concept and feasibility of merged bipolar/sidewall MOS transistors (BiMOS transistors) are demonstrated by fabricating and characterizing the structures. The NMOS-input Darlington pair was merged into an NMOS-input BiMOS Darlington transistor which occupies 1.2 times the area of a single n-p-n bipolar transistor. It should be possible to form other BiCMOS subcircuit elements such as the PMOS-input BiMOS Darlington transistor and BiCMOS static memory cell. An initial analysis of the doping requirements for the base of the n-p-n bipolar transistor and the channel of the sidewall MOS transistors suggests that the requirements are compatible.<>
