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.
