Claim:
1. A capacitor structure, comprising: a dielectric layer, located on a substrate; a first conductive layer, located in the dielectric layer; and a cup-shaped capacitor, penetrating through the first conductive layer and located in the dielectric layer, wherein the cup-shaped capacitor comprises: a bottom electrode, wherein two sidewalls of the bottom electrode are electrically connected to the first conductive layer; a capacitor dielectric layer, covering a surface of the bottom electrode; a top electrode, covering a surface of the capacitor dielectric layer, wherein the capacitor dielectric layer is disposed between the top electrode and the bottom electrode, and a top surface of the bottom electrode is lower than a top surface of the top electrode; and a plurality of vias disposed in the dielectric layer at a side of the cup-shaped capacitor, wherein one of the vias is electrically connected to the bottom electrode through the first conductive layer.
