Abstract
Proposed are thin film MIM capacitors with which deterioration of insulating properties and leakage current properties can be sufficiently inhibited. Also proposed is a manufacturing method for the thin film MIM capacitors. For the thin film MIM capacitor (), a lower electrode (), a base metal thin film (), the dielectric thin film () and the upper electrode () are formed to approximately the same area. The lower electrode () has a configuration that differs from the other films to form a part for external connection. The side surface of the base metal thin film (), the dielectric thin film (), and the upper electrode () are covered with a base metal oxide () that comprises the same metal atoms as the base metal thin film ().
