Abstract
A method for aligning quantum dots effectively controls a growth position of the quantum dots for obviating an irregularity of a position of spontaneous formation quantum dots, and thus aligns the quantum dots in one-dimension (1-D) or two-dimension (2-D). A semiconductor device fabricated using the method manufactures a superlattice layer layer for adjusting an internal strain distribution by alternately depositing two semiconductor materials having different lattice constant, and grows spontaneous formation quantum dots on the superlattice layer. As a result, a strained force caused by the superlattice layer influences on the quantum dots so that the quantum dots can be regularly aligned.
