Abstract:
Integrated circuit structures including device terminal interconnect pillar structures, and fabrication techniques to form such structures. Following embodiments herein, a small transistor terminal interconnect footprint may be achieved by patterning recesses in a gate interconnect material and/or a source or drain interconnect material. A dielectric deposited over the gate interconnect material and/or source or drain interconnect material may be planarized to expose portions of the gate interconnect material and/or drain interconnect material that were protected from the recess patterning. An upper level interconnect structure, such as a conductive line or via, may contact the exposed portion of the gate and/or source or drain interconnect material.
