ABSTRACT:
A semiconductor memory has at least one V-MOS transistor which includes a trench and a storage capacitor. A semiconductor substrate is doped with concentration centers of a first conductivity type and has a buried layer which is doped with concentration centers of a second conductivity type opposite to the first conductivity type. At least two additional layers are divided by the trench and have alternately differing conductivity types, the two additional layers and the buried layer being produced by diffusion and/or implantation.
