    • PURPOSE: A method for forming a quantum dot of a semiconductor device is provided to apply the device as a SET component as well as light emitting devices in the optical field by forming quantum dots which are small and relatively uniform. CONSTITUTION: The method includes following steps. At the first step, an insulator layer(1,3) is formed on a substrate. At the second step, a conductive layer(2) is formed on the insulator layer. At the last step, heat processing operation is perform to accumulate the conductive layer. The insulator layer is made of a silicon oxide layer, and the conductive layer is formed from one of a group including Si, Ge, Si(1-x)Ge(x), Al, Au, Cu, Pt, Cr, Ru, Ta, or Si alloy(Si(1-x)-metal(x)), or alloy of the preceding materials and Ge(Ge(1-x)-metal(x)), or alloy of the preceding materials(metal(1-x)-metal(x)). The heat processing operation is performed under a vacuum environment of N2 environment.
