The doped regions define sources and drains. Gate stacks are formed over regions of oxide adjacent the doped regions. A planarized insulator is formed between the gate stacks. Openings are provided in the planarized insulator for contacts to the doped regions and the gate stacks. Conductive material fills the openings to form contacts for the doped regions and for the gate stacks. A patterned layer of conductive material on the planarized insulator connects selected ones of the contacts for wiring portions of the latch.
