Abstract
In order to avoid the capacitors in a stacked capacitor structure suiting a miniaturization process from collapsing to cause a short-circuit, separated reinforced structures are used and disposed at the outer-sidewalls of the capacitor, which not only reduces the space occupied by the reinforced structure to increase the surface areas of the upper electrode and the lower electrode of the capacitor, but also allows the capacitor to be deflected but collapse-proof and there are more spaces between the capacitors, so as to solve the filling difficulty problem due to a too small filling space in a successive process of depositing conductive material into the filling space.
