Abstract
A thin film capacitor includes a body including a lower electrode formed on a substrate, a plurality of first electrode layers, and a plurality of second electrode layers stacked alternately with the plurality of first electrode layers, with one of the dielectric layers interposed therebetween. The lower electrode and the first electrode layer have the same polarity as each other, and surface roughness of the first and second electrode layers is less than that of the dielectric layers, thereby securing capacitance and characteristics of the dielectric layers.
