In order to reduce a vertical etching profile at a lower portion of a hole where a charge storage electrode, an impurity is doped into the interlayer insulating film wherein the difference in concentration of the impurity at a lower portion and at an upper portion of the interlayer insulating film is controlled to make the etching rate at the lower portion of the interlayer insulating film faster than that at the upper portion of the interlayer insulating film using a wet etching process. Therefore, the region where a lower electrode will be formed has a maximum width to prevent a decrease in the capacitance of the capacitor.
