Abstract:
The present invention discloses a semiconductor structure with capacitor landing pad and a method for fabricating a capacitor landing pad. The semiconductor structure with capacitor landing pad includes a substrate having a plurality of contact structures, a first dielectric layer disposed on the substrate and the contact structures, and a plurality of capacitor landing pads, each of the capacitor landing pads being located in the first dielectric layer and electrically connected to the contact structure, wherein the capacitor landing pads presents a shape of a wide top and a narrow bottom and a top surface of the capacitor landing pads have a concave shape.

Claim (Index 1):
A method of fabricating a capacitor landing pad, comprising:\n providing a substrate having a plurality of contact structures therein; forming a first dielectric layer on the substrate; forming a plurality of first recesses in the first dielectric layer, wherein each of the first recesses exposes one of the contact structures and presents a shape of a wide top and a narrow bottom; and filling a contact material in the first recesses to form capacitor landing pads, wherein top surfaces of the capacitor landing pads have a concave shape.
