Provided is a semiconductor device that comprises a metal gate having a low sheet resistance characteristic and a high diffusion barrier characteristic and a method of fabricating the metal gate of the semiconductor device. The adhesive dispersions are prepared by copolymerizing a denatured vegetable protein, such as soy flour, that has been functionalized with methylol groups with one or more reactive comonomers, and preparing an acidic dispersion of the adhesive. The bushing opening receives a shaft of a liner fastener, wherein the fastener is connectable with a duct liner. The system includes one or more controllers to process transaction events in an industrial automation environment. The orthodontia metalwork may be used to form an antenna.
