Claim 13:
14. A semiconductor memory device comprising:
a plurality of first electrodes, having opposite sidewall;
a first high-k dielectric layer, disposed on the opposite sidewalls of each of the first electrodes, wherein a portion of the opposite sidewalls of the first electrodes is exposed from the first high-k dielectric layer;
a supporting layer, disposed between the first high-k dielectric layer disposed on the opposite sidewalls to connect with thereto;
a second high-k dielectric layer, disposed on the first electrodes, the first high-k dielectric layer and the first supporting layer, wherein the second high-k dielectric layer directly contacts the portion of the sidewalls of the first electrodes; and
a second electrode, disposed on the second high-k dielectric layer.
