Abstract:
A capacitor comprising:a semiconductor substrate;an impurity region in the semiconductor substrate;a first insulating layer on the semiconductor substrate, the first insulating layer having a first contact hole to expose the impurity region;a first conductive layer in the contact hole;a second conductive layer on the first insulating layer, the second conductive layer having a first end portion contacting the first conductive layer and a second end portion on the first insulating layer;a second insulating layer on the first insulating layer including the second conducive layer, the second insulating layer contacting the first end portion of the second conductive layer;a lower electrode over the second insulating layer, the lower electrode not overlapping the first conductive layer in a direction perpendicular to the semiconductor substrate;a dielectric layer on the lower electrode including the second insulating layer; andan upper electrode on the dielectric layer.
