Abstract:
A semiconductor device comprising a capacitor having first and second electrodes and a dielectric layer sandwiched between said first electrode and said second electrode, said first electrode including an inner cylindrical portion and an outer cylindrical portion having a height substantially smaller than a height of said inner cylindrical portion and further having an insulating layer disposed over the first and second electrodes and over an adjoining region of the semiconductor device adjacent the capacitor so that said insulating layer has a step angle .theta. of 40.degree. or less in the vicinity of a boundary between a region in which the capacitor is disposed and the adjoining region, said boundary having a sloping surface, said angle .theta. measured between a straight line extending from said sloping surface and a surface of the second electrode at the boundary, the second electrode comprising a plate electrode at the boundary.
