Abstract
A stacked capacitor of the fin-like structure is provided wherein the plurality of polysilicon layers constituting the storage electrode are connected with each other in the sawtooth-like manner to overcome the structural instability of the fin-like structure. The polysilicon layers constituting the storage electrode are extended overlaying each other, so that the capacity of the capacitor in a highly integrated DRAM may be increased without increasing the area occupied by the capacitor.
