Before revision: For example Global Foundries (formerly IBM) offer a basic 180nm BiCMOS7WL process and several other BiCMOS processes optimized in various URL These processes also include steps for the deposition of precision resistors, and high Q Rf inductors and capacitors on-chip, which are not needed in a "pure" CMOS logic design.
