Abstract
Disclosed herein are non-volatile memory devices with asymmetric source/drain junctions and a method for fabricating the same. According to the method, a gate stack is formed on a semiconductor substrate, and impurity ions are implanted at a predetermined angle to form a source/drain junction in the semiconductor substrate. Thermal treatment of the semiconductor substrate forms an asymmetrically disposed source/drain junction between adjacent gate stacks.
