Abstract
According to one example, a method includes epitaxially growing first portions of a plurality of elongated semiconductor structures on a semiconductor substrate, the elongated semiconductor structures running perpendicular to the substrate. The method further includes forming a gate layer on the substrate, the gate layer contacting the elongated semiconductor structures. The method further includes performing a planarization process on the gate layer and the elongated semiconductor structures, and epitaxially growing second portions of the plurality of elongated semiconductor structures, the second portions comprising a different material than the first portions.
