A method for forming a semiconductor device. A substrate, having a plurality of deep trench capacitors therein, is provided wherein upper portions of the deep trench capacitor devices are revealed. Spacers on sidewalls of the upper portions of the deep trench capacitors are formed to form a predetermined region surrounded by the deep trench capacitor devices. The predetermined region of the substrate is etched using the spacers and the upper portions of the deep trench capacitors serve as a mask to form a recess, and a recessed gate is formed in the recess.
