Abstract:
A semiconductor apparatus having a charge pump circuit which includes MOSFETs and MOS capacitors formed on the same substrate, wherein at least one of said MOS capacitors comprises:a multiplicity of first electrodes formed at multiple locations within one region of said substrate, wherein said multiplicity of first electrodes are interconnected; insulating layers formed on/above respective substrate regions between neighboring first electrodes, each layer covering at least the respective substrate region; and a multiplicity of second electrodes formed on/above said respective insulating layers, wherein said multiplicity of second electrodes are interconnected; wherein said one region is a semiconductor region having a specific conduction type isolated from other regions by isolation regions, and each of said multiplicity of first electrodes has a high conductivity and is formed by increasing the conductivity of said one region, and said insulating layer is an insulating oxide layer, and, and wherein the number of said first electrodes is equal to or greater than 3; and wherein all said first electrodes have the same conduction type, and all said first electrodes being formed within one region of the same conduction type.
