Abstract:
A method of manufacturing a semiconductor device, comprising the steps of:forming a plurality of storage electrodes at respective positions over a major surface of a semiconductor substrate;sequentially depositing a high-permittivity film and a first counter electrode on said plurality of storage electrodes;processing said high-permittivity film and said first counter electrode to form a plurality of high-permittivity films and a plurality of first conductive electrodes on said plurality of storage electrodes;burying a first insulating film between a plurality of convex multi-layered structures, said plurality of convex multi-layered structures being adjacent each other and consisting of said storage electrodes, said high-permittivity films, and said first counter electrodes, said first insulating film having a permittivity much lower than a permittivity of each of said high-permittivity films; andforming a second counter electrode on upper surfaces of said first insulating film and said plurality of first counter electrodes so as to connect upper surfaces of said first counter electrodes exposed on a surface of said first insulating film.
