摘要： PROBLEM TO BE SOLVED: To provide an improved film capacitor structure which allows simple access to any of a number of electrodes or combination of electrodes.SOLUTION: A multi-layer film capacitor structure has a bottom electrode layer on a monolithic substrate, intermediate pairs of layers of a film electrode and a dielectric material which overlie the bottom electrode, and a top pair of layers of a film electrode and a film dielectric overlying the intermediate pairs. The structure preferably has a mesa configuration, in which each electrode layer extends laterally beyond the periphery of the layers above it around the entire periphery of the device. Each electrode layer has a top surface which is accessible at its projecting edge through a via, so that the electrodes can be accessed in any combination to permit any desired circuit connection. If desired, the dielectric materials can have different frequency characteristics, allowing a single capacitor structure to be optimized for a filter.
