Abstract:
1. A semiconductor structure, comprising: (a) a semiconductor substrate; (b) an electrically conducting region in the semiconductor substrate, (c) a first doped semiconductor region (i) in the semiconductor substrate, (ii) wrapping around side walls and a bottom wall of the first portion of the electrically conducting region, but (iii) electrically insulated from the first portion of the electrically conducting region by both a capacitor dielectric layer and a first portion of a collar dielectric layer; and (d) a second doped semiconductor region (i) in the semiconductor substrate, (ii) wrapping around side walls of the second portion of the electrically conducting region, but (iii) electrically insulated from the second portion of the electrically conducting region by a second portion of the collar dielectric layer,
