Abstract:
Methods for producing FETs with negative capacitance and the resulting device are disclosed. Embodiments include forming a gate stack over a semiconductor substrate by: forming a gate oxide over the semiconductor substrate; forming a first metal gate electrode over the gate oxide; forming a dummy gate over the metal gate electrode; and forming sidewall spacers on first and second sides of the gate stack; forming an ILD over the substrate and gate stack; removing the dummy gate and at least a portion of sidewall spacers to form an opening; forming a ferro-electric (FE) layer in the opening; and forming a second metal gate electrode over the FE layer.

Claim (Index 1):
A method comprising:\n forming a gate stack over a semiconductor substrate by:\n forming a gate oxide over the semiconductor substrate; \n forming a first metal gate electrode over the gate oxide; \n forming a dummy gate over the metal gate electrode; and \n forming sidewall spacers on first and second sides of the gate stack; \n forming an interlayer dielectric (ILD) over the substrate and gate stack; removing the dummy gate and at least a portion of sidewall spacers to form an opening; forming a ferro-electric (FE) layer in the opening; and forming a second metal gate electrode over the FE layer, wherein vertical portions of the FE layer extends from an upper surface of the ILD down to the semiconductor substrate and below the first metal gate electrode, and wherein a horizontal portion of the FE layer extends between the vertical portions and separates the first metal gate electrode and the second metal gate electrode.
