Abstract
There is provided a semiconductor device, including: a semiconductor substrate having a major surface; a first insulating film formed on the major surface of the semiconductor substrate; a plurality of first conductive members spaced apart from each other on the first insulating film and formed to be connected to the semiconductor substrate; a plurality of storage electrodes formed on the first insulating film at positions respectively corresponding to the first conductive members; a plurality of high-permittivity films respectively stacked on the plurality of storage electrodes; a plurality of first counter electrodes respectively stacked on the plurality of high-permittivity films; a second insulating film, having a permittivity much lower than a permittivity of each of the high-permittivity films, for insulating the first conductive members, the high-permittivity films, and the first counter electrodes, respectively; and a second counter electrode, formed on the second insulating film, for connecting adjacent first counter electrodes on an upper surface of the second counter electrode, and a method of manufacturing the semiconductor device.
