A method for forming double-sided capacitors for a semiconductor device
includes forming a dielectric structure which supports capacitor bottom
plates during wafer processing. The structure is particularly useful for
supporting the bottom plates during removal of a base dielectric layer to
expose the outside of the bottom plates to form a double-sided capacitor.
The support structure further supports the bottom plates during formation
of a cell dielectric layer, a capacitor top plate, and final supporting
dielectric. An inventive structure is also described.
