Patent ID: 8841748

Claim:
A semiconductor device, comprising: a semiconductor wafer having a front face; a dielectric layer on the front face of the semiconductor wafer, said dielectric layer including a front electrical connection comprising an electrical connection portion embedded within the dielectric layer at a position offset from and parallel to said front face; a blind hole formed in a rear face of the semiconductor wafer and having a depth passing completely through the semiconductor wafer and partially through the dielectric layer to reveal a rear face of the electrical connection portion; a capacitor formed in the blind hole, comprising: a first conductive layer covering a lateral wall of the blind hole and at least a portion of the rear face of the electrical connection portion and forming an outer electrode of the capacitor, a dielectric intermediate layer covering said first conductive layer and forming a dielectric membrane, and a second conductive layer covering the dielectric intermediate layer and forming an inner electrode of the capacitor, and a rear electrical connection for the inner electrode.
