Patent ID: 8729665

Claim:
An integration device ( 102 ), the integration device comprising a semiconductor substrate ( 106 ) with a first substrate side ( 1 ) and an opposite second substrate side ( 2 ); a through-substrate via ( 162 ) extending from the first substrate side ( 1 ) to the second substrate side ( 2 ); a trench capacitor ( 118 ) in the semiconductor substrate ( 106 ); wherein the trench capacitor has a trench filling ( 120 to 138 ) that includes a number of at least four electrically conductive capacitor-electrode layers ( 122 , 126 , 130 , 134 , 138 ) in an alternating arrangement with dielectric layers ( 120 , 124 , 128 , 132 ), such that the different capacitor-electrode layers are electrically isolated from each other; the capacitor-electrode layers are connected to capacitor terminals ( 150 , 160 ) provided on the first or second substrate side, and wherein the trench capacitor ( 118 ) and the through-substrate via ( 162 ) are formed in respective trench ( 119 ) and via openings ( 161 ) in the semiconductor substrate, which have an equal lateral extension (w) exceeding 10 micrometer.
