CAPACITOR AND METHOD FOR FABRICATING THE SAME

摘要

PURPOSE: A capacitor and a manufacturing method thereof are provided to obtain high capacitance by widening a contact layer in contact with a storage node and a storage node contact plug than the width of the storage node. CONSTITUTION: A storage node contact plug(108) is provided. A contact layer covers a storage node contact plug. A storage node(112A) is formed on the contact layer to expose the part of the contact layer. A dielectric film is formed along the cross section of the storage node and the exposed contact layer. A plate(115) is formed on the dielectric film.
