A method for fabricating a quantum dot, which can be used to fabricate a single electron memory device. The method includes forming a first insulation layer on a semiconductor layer, then forming a second insulation layer on the first insulation layer. Next, the second insulation layer is patterned to form an opening to partially expose the upper surface of the first insulation layer. Using the opening in the second insulation layer, a silicon ion is then implanted into the first insulation layer through the opening by using a tilt angle ion implantation method. Finally, the semiconductor layer is treated to re-crystallize the silicon ion implanted into the first insulation layer.
