Abstract:
A semiconductor structure with a capacitor landing pad includes a substrate. A capacitor contact plug is disposed on the substrate. A capacitor landing pad contacts and electrically connects the capacitor contact plug. A bit line is disposed on the substrate. A dielectric layer surrounds the capacitor landing pad. The dielectric layer includes a bottom surface lower than a top surface of the bit line.

Claim (Index 6):
A fabricating method of a capacitor landing pad, comprising:\n providing a substrate, wherein a plurality of word lines are embedded in the substrate, a plurality of insulating layers are disposed on the word lines, each of the insulating layers is respectively disposed directly on one of the word lines, and an opening is defined between the insulating layers adjacent to each other; forming a metal layer filling in the opening, wherein the insulating layers are entirely embedded in the metal layer; forming a first hard mask covering the metal layer; performing a first pattern process to transform the first hard mask into a plurality of second hard masks by patterning the first hard mask; performing a second pattern process to transform the second hard masks into a plurality of third hard masks by patterning the second hard masks, wherein each of the third hard masks does not connect to another third hard mask, and each of the third hard masks partly overlaps one of the insulating layers; removing the metal layer by taking the third hard masks as a mask to form a trench in the metal layer, wherein the trench extends into the opening, a bottom of the trench is lower than a top surface of the insulating layers, and the trench defines the capacitor landing pad on the metal layer; and forming a dielectric layer filling up the trench.
