Abstract
A stacked CMOS structure is disclosed which uses buried N++ source and drain for the non-self-aligned bulk N-channel driver devices together with an oversized polygate on which a non-self aligned P-channel load device is made from a second layer of poly or recrystallized poly. The non-self aligned pair of stacked devices provides increased density of devices per unit area with a simple process at the cost of increased gate to source and gate to drain parasitic capicitances.
