Abstract
The present invention relates to a manufacturing method for a recessed channel array transistor and a corresponding recessed channel array transistor. In one embodiment, the present invention uses a self-adjusting spacer on the substrate surface to provide the required distance between the gate and the source/drain regions. Thus, the requirements regarding the tolerances of the lithography in the gate contact plane are diminished.
