Abstract
A method includes forming a transistor over a substrate, wherein the transistor includes a source, a drain over the source, a semiconductor channel between the source and the drain, and a gate surrounding the semiconductor channel. A silicide layer is formed over the drain of the transistor. A capping layer is formed over the silicide layer. Portions of the capping layer and the silicide layer are removed to define a drain pad over the drain of the transistor.
