Abstract
Silicon-on-insulator mesa steps cause high resistance in polycrystalline material because of the lack of silicide coverage. In a gate or word line, for instance, this accounts for a large resistance. By connecting the mesas through the body nodes of adjacent transistors, all mesa steps in a polycrystalline semiconductor gate are eliminated. Thus, gate or word line resistance is reduced.
