Claim 14:
15. A semiconductor device comprising:
a first high dielectric constant layer;
a plurality of first electrodes penetrating the first high dielectric constant layer;
a plurality of second electrodes penetrating the first high dielectric constant layer to a depth different from that of the plurality of first electrodes;
a second high dielectric constant layer located on the first high dielectric constant layer;
a plurality of third electrodes penetrating the second high dielectric constant layer, the plurality of third electrodes being electrically connected to the second electrodes; and
a plurality of fourth electrodes penetrating the second high dielectric constant layer to a depth different from that of the plurality of third electrodes, the plurality of fourth electrodes being spaced apart from the plurality of first electrodes.
