A method for fabricating a capacitor includes: forming a bottom electrode; forming a dielectric layer on the bottom electrode; forming a metal oxide layer including a metal having a high electronegativity on the dielectric layer; forming a sacrificial layer on the metal oxide layer to reduce the metal oxide layer to a metal layer; and forming a top electrode on the sacrificial layer to convert the reduced metal layer into a high work function interface layer.

A structure of a semiconductor includes an isolation structure in a well of a substrate. An upper surface of the isolation structure in the well of the substrate is lower than an upper surface of the substrate and an upper surface of the well. A gate electrode has a first portion over the isolation structure, and a second portion laterally adjacent to the first portion, and above the first portion.

A conductive strap structure in lateral contact with a top semiconductor layer is formed on an inner electrode of a deep trench capacitor. A cavity overlying the conductive strap structure is filled a dielectric material to form a dielectric capacitor cap having a top surface that is coplanar with a topmost surface of an upper pad layer. A semiconductor mandrel in lateral contact with the dielectric capacitor cap is formed. The combination of the dielectric capacitor cap and the semiconductor mandrel is employed as a protruding structure around which a fin-defining spacer is formed. The semiconductor mandrel is removed, and the fin-defining spacer is employed as an etch mask in an etch process that etches a lower pad layer and the top semiconductor layer to form a semiconductor fin that laterally wraps around the conductive strap structure. An access finFET is formed employing two parallel portions of the semiconductor fin.
