Disclosed is a capacitor structure and method for forming the same. This structure has a conductive substrate, conductive fins extending above the substrate, and trenches extending into the substrate. These trenches are positioned between locations where the fins extend above the substrate. The invention includes an insulator in the trenches and covering the fins. This insulator separates the substrate and fins from a conductive top plate that covers the fins and fills the trenches. A bottom plate contact electrically connects the fins and the substrate such that the fins and the substrate comprise a bottom plate of the capacitor structure.

A body contact structure utilizing an insulating structure between the body contact portion of the active area and the transistor portion of the active area is disclosed. In one embodiment, the present invention substitutes an insulator for at least a portion of the gate layer in the regions between the transistor and the body contact. In another embodiment, a portion of the gate layer is removed and replaced with an insulative layer in regions between the transistor and the body contact. In still another embodiment, the insulative structure is formed by forming multiple layers of gate dielectric between the gate and the body in regions between the transistor and the body contact. The body contact produced by these methods adds no significant gate capacitance to the gate.
