Abstract:
An integrated FinFET and deep trench capacitor structure and methods of manufacture are provided. The method includes forming deep trench capacitor structures in a silicon on insulator (SOI) wafer. The method further includes forming a plurality of composite fin structures from a semiconductor material of the SOI wafer and conductive material of the deep trench capacitor structures. The method further includes forming a liner over the deep trench capacitor structures including the conductive material of the deep trench capacitor structures. The method further includes forming replacement gate structures with the liner over the deep trench capacitor structures protecting the conductive material during deposition and etching processes.

Claim (Index 17):
A method of forming a deep trench capacitor and a FinFET, comprising:\n patterning semiconductor material and one or more deep trench capacitors to form composite fins; segmenting the composite fins to create a plurality of composite fin structures with conductive material of the one or more deep trench capacitors self-aligned and in contact with at least one end of the semiconductor material making a portion of the composite fin structures; recessing the conductive material in unprotected portions during the forming of the composite fins; forming a film of dielectric material over the recessed conductive material of the one or more deep trench capacitors; providing protective capping materials within the recessed conductive material and which comprise an oxide material directly over a top surface of the conductive material of the one or more deep trench capacitors, a nitride material directly over the oxide material, and the film of dielectric material directly over the nitride material; and forming replacement gate structures with the film of dielectric material over the one or more deep trench capacitor structures protecting the conductive material during deposition and etching processes, wherein the providing of the protective capping materials comprises depositing the film of dielectric material including a high-k dielectric material over the deep trench capacitor structures and annealing the high-k dielectric material.
