Abstract
A method for fabricating a compound semiconductor substrate having a quantum dot array structure includes the steps of forming a plurality of dielectric thin layer patterns on a substrate, thereby forming an exposed area of the substrate, sequentially forming buffer layers and barrier layers in a pyramid shape on the exposed area of the substrate, forming Ga droplets on the barrier layers, transforming the Ga droplets into GaAs quantum dots, performing a thermal process to the substrate, and growing the buffer layers and the barrier layers to thereby form a passivation layer capping the GaAs quantum dots.
