摘要:
A thin film capacitor includes a body having first and second electrode layers and first and second dielectric layers alternately stacked on a substrate. A thickness of the first dielectric layer is 1.2 to 3 times that of the second dielectric layer. Therefore, leakage current characteristics of the dielectric layers may be improved, and capacitance of the thin film capacitor may be secured.
