A high speed bulk CMOS C2L microprocessor

THIS PAPER will discuss a structural form of self-aligned silicon-gate technology - C2L - a Closed COS/MOS Logic approach to extend the capability of CMOS design by affording improvement in speed, packing density, yields, and process simplicity. The technique has been found to approach circuit speeds on low-cost bulk silicon previously only possible with SOS (Silicon-on-Sapphire) technology. C2L approach can be considered a CMOS counterpart to bipolar 12L in that it is also based on a common-source approach to logic.
