Abstract:
Integrated circuits including MOSFETs with selectively recessed gate electrodes. Transistors having recessed gate electrodes with reduced capacitive coupling area to adjacent source and drain contact metallization are provided alongside transistors with gate electrodes that are non-recessed and have greater z-height. In embodiments, analog circuits employ transistors with gate electrodes of a given z-height while logic gates employ transistors with recessed gate electrodes of lesser z-height. In embodiments, subsets of substantially planar gate electrodes are selectively etched back to differentiate a height of the gate electrode based on a given transistor's application within a circuit.

Claim (Index 2):
An integrated circuit structure, comprising:\n a first MOS transistor, comprising:\n a first gate dielectric over a first fin; \n a first gate electrode over the first gate dielectric, the first gate electrode having a first work function layer and a first bulk material, the first gate electrode having a first gate length; \n a first source or drain structure adjacent a first side of the first gate electrode; and \n a second source or drain structure adjacent a second side of the first gate electrode, the second side opposite the first side; \n a first conductive contact structure in direct contact with the first source or drain structure, wherein the first bulk material of the first gate electrode has an uppermost surface below an uppermost surface of the first conductive contact structure; and a second MOS transistor, comprising:\n a second gate dielectric over a second fin; \n a second gate electrode over the second gate dielectric, the second gate electrode having a second work function layer and a second bulk material, the second gate electrode having a second gate length, the second gate length greater than the first gate length; \n a third source or drain structure adjacent a first side of the second gate electrode; and \n a fourth source or drain structure adjacent a second side of the second gate electrode, the second side opposite the first side; and \n a second conductive contact structure in direct contact with the third source or drain structure, wherein the second bulk material of the second gate electrode has an uppermost surface above an uppermost surface of the second conductive contact structure.
