Claim 19:
20. A semiconductor device comprising:
a first insulating layer;
a first electrode penetrating the first insulating layer;
a second electrode penetrating the first insulating layer, the second electrode being adjacent to the first electrode;
a capping layer over the first insulating layer;
a first high dielectric constant layer having a dielectric constant higher than a dielectric constant of the first insulating layer, wherein the first high dielectric constant layer is located over the capping layer;
a third electrode penetrating the first high dielectric constant layer and the capping laver, the third electrode being connected to the first electrode; and
a fourth electrode penetrating the first high dielectric constant layer and the capping layer, the fourth electrode being located adjacent to the third electrode.
