PURPOSE: A new type of a capacitor layout is provided to prevent a bridge between adjacent storage nodes, by designing a capacitor of a rectangular type, by forming each sub capacitor pattern on and under a main capacitor pattern of the rectangular type and by designing main and sub capacitor patterns in adjacent rows shifted from each other by a predetermined interval. CONSTITUTION: A unit capacitor pattern is designed in a manner that a sub pattern of a relatively small rectangular type is formed one and under each main pattern of a rectangular type. The right side surface of the main patterns in an odd-numbered row of adjacent unit capacitor patterns is designed to be in contact with the right side surface of the wordline in the even-numbered column. The sub patterns are designed to be disposed on and under the center part of the main pattern. The left side surface of the main patterns in the even-numbered row comes in contact with the left side surface of the wordline in the odd-numbered column. The sub patterns are disposed in the right end of the main patterns.
