A method for manufacturing a semiconductor device capacitor includes the steps of forming a first conductive layer on a semiconductor substrate, forming a storage node pattern on the first conductive layer, forming first conductive sidewalls on the side surfaces of the storage node pattern, removing the storage node pattern, forming material sidewalls on the side surfaces of the conductive sidewalls, forming second conductive sidewalls on the side surfaces of the material sidewalls, and removing the material sidewalls. Thus, a process simplification is achieved and capacitance is increased easily so that a high-integration memory cell can be ensured.
