Abstract
A semiconductor device that prevents the leaning of storage node when forming a capacitor having high capacitance includes a plurality of cylinder-shaped storage nodes formed over a semiconductor substrate; and support patterns formed to fix the storage nodes in the form of an 'L' or a '+' when viewed from the top. This semiconductor device having support patterns in the form of an ‘L’ or a ‘+’ reduces stress on the storage nodes when subsequently forming a dielectric layer and plate nodes that prevents the capacitors from leaking.
