Abstract: PURPOSE: A method of forming a buried contact is to prevent a plate electrode from being contacted by an annealing operation, and thus prevent electric disconnection between a capacitor and an active region of a transistor. CONSTITUTION: A buried contact(19) is a path for connecting a storage electrode and an active region. A planar size of the buried contact is increased at a cell around a cell block. A dummy buried contact is formed around the cell block. The dummy buried contact around the cell block and the buried contact of a substantially functional cell have a larger planar size than the buried contact at a center portion. The number of buried contact is restricted into 200 in a line or row. If the number of the buried contact is so small, a resistance with respect to thermal deformation is reduced. If the number of the buried contact is so many, a space for forming a cell is reduced. Since the size of the buried contact is large in a direction that the plate electrode is displaced, the resistance with respect to the displacement is increased. In case the plate electrode is inclined, the connection is maintained.
