Abstract:
A trench capacitor includes at least one epitaxial semiconductor surface layer on a semiconductor substrate having a doping level that is less than a doping level of the semiconductor substrate. A plurality of trenches are formed through at least one half of a thickness of the epitaxial semiconductor surface layer. The epitaxial semiconductor surface layer is thicker than a depth of the plurality of trenches. At least one capacitor dielectric layer lines a surface of the trenches. At least one trench fill layer on the dielectric layer fills the trenches.

Claim (Index 1):
A method for forming a trench capacitor, comprising:\n providing at least one epitaxial semiconductor surface layer on a semiconductor substrate having a doping level that is less than a doping level of the semiconductor substrate; forming a plurality of trenches through at least one half of a thickness of the epitaxial semiconductor surface layer, wherein the epitaxial semiconductor surface layer is thicker than a depth of the plurality of trenches; forming at least one capacitor dielectric layer that lines a surface of the plurality of trenches; depositing at least one trench fill layer on the dielectric layer to fill the plurality of deep trenches, and etching the trench fill layer to etch back the trench fill layer in regions lateral to the plurality of trenches.
