Abstract: PURPOSE: To provide a method for fabricating a capacitor in a semiconductor memory in which integration of the semiconductor memory can be enhanced by ensuring a sufficient charge storage capacity even if the share factor of a memory cell is decreased. CONSTITUTION: A planarized insulation oxide 7 is deposited on a semiconductor substrate on which transistors having impurity diffusion region are fabricated, and the insulation oxide is etched to expose the impurity diffusion region using a contact hole mask. An electrode substance layer is then formed on the insulation oxide such that it is connected electrically with the impurity diffusion region and a sacrifice oxide pattern having a bird's beak shape is formed at a part on the electrode substance layer where a contact hole is located. Subsequently, an electrode substance layer pattern is formed by removing the electrode substance layer to expose the insulation oxide using the sacrifice oxide pattern as an etching obstacle. Thereafter, upper surface of the electrode substance layer pattern is exposed by wet etching the sacrifice oxide pattern and a dielectric layer 18 and a plate electrode 19 are formed sequentially on the entire exposed surface of the electrode substance layer pattern.
