Abstract:
A trench capacitor includes a plurality of trenches in a doped semiconductor surface layer of a substrate. At least one dielectric layer lines a surface of the plurality of trenches. A second polysilicon layer that is doped is on a first polysilicon layer that is on the dielectric layer which fills the plurality of trenches. The second polysilicon layer has a higher doping level as compared to the first polysilicon layer.

Claim (Index 5):
The method of  claim 4 , further comprising after the removing the first polysilicon layer and the second polysilicon layer from a back side of the substrate, depositing a dielectric capping layer, performing an annealing process at a temperature of 900 to 1050\u00b0 C., removing the dielectric capping layer, and partial top side etching of the second polysilicon layer on the first polysilicon layer before the top side polysilicon etching.
