  • Patent number: 9349864
    Abstract: Methods for fabricating integrated circuits including selectively forming layers of increased dopant concentration are provided. In an embodiment, a method for fabricating an integrated circuit includes forming a material layer with a selected facet on a selected plane and a non-selected facet on a non-selected plane. The method further includes performing an epitaxial deposition process with a dopant source to grow an in-situ doped epitaxial material on the material layer. The epitaxial deposition process grows the in-situ doped epitaxial material on the selected facet at a first growth rate and over the non-selected facet at a second growth rate greater than the first growth rate. A layer of increased dopant concentration is selectively formed over the selected facet.
