摘要:
A bottle shaped trench for an SOI capacitor is formed by a simple processing sequence. A non-conformal dielectric layer with an optional conformal dielectric diffusion barrier layer underneath is formed on sidewalls of a deep trench. Employing an isotropic etch, the non-conformal dielectric layer is removed from a bottom portion of the deep trench, leaving a dielectric spacer covering sidewalls of the buried insulator layer and the top semiconductor layer. The bottom portion of the deep trench is expanded to form a bottle shaped trench, and a buried plated is formed underneath the buried insulator layer. The dielectric spacer may be recessed during formation of a buried strap to form a graded thickness dielectric collar around the upper portion of an inner electrode. Alternately, the dielectric spacer may be removed prior to formation of a buried strap.

A semiconductor device is formed by providing a substrate and forming a semiconductor-containing layer atop the substrate. A mask having a plurality of openings is then formed atop the semiconductor-containing layer, wherein adjacent openings of the plurality of openings of the mask are separated by a minimum feature dimension. Thereafter, an angled ion implantation is performed to introduce dopants to a first portion of the semiconductor-containing layer, wherein a remaining portion that is substantially free of dopants is present beneath the mask. The first portion of the semiconductor-containing layer containing the dopants is removed selective to the remaining portion of semiconductor-containing layer that is substantially free of the dopants to provide a pattern of sublithographic dimension, and the pattern is transferred into the substrate to provide a fin structure of sublithographic dimension.
