Abstract (en)

[origin: DE4428195C1] In order to produce a silicon capacitor, holes are created in an n-doped silicon substrate (1); across the surface of the holes a conducting region (40) is created through doping and a dielectric layer (6) and a conducting layer (7) are provided. To compensate for mechanical stresses in the silicon substrate resulting from the doping of the conducting region (40), the conducting region (40) is in addition doped with germanium which diffuses out from a germanium-doped layer.
