A method for maintaining a smooth surface of crystallizable material is disclosed. First, a substrate is provided. A target material layer is then formed on the substrate, with the target material being a crystallizable material. A protecting layer is subsequently formed on the target material layer. Next, an annealing treatment is implemented, with the surface of the target material layer, facing the protecting layer, being maintained in its original smooth state by the pressure and/or adhesion of the protecting layer. Finally, the protecting layer is removed to leave an open and smooth surface of the processed crystallizable material.

A semiconductor laser device that has the effect of phonon-assisted light amplification and a method for manufacturing the same are proposed. A conductive layer is formed on a semiconductor silicon substrate. A current flow is used to accomplish electro-luminescence of silicon. A silicon dioxide nanometer particle layer is sandwiched between the conductive layer and the semiconductor silicon substrate to form a MOS junction for carrier confinement. The phonon-assisted light emission mechanism can thus be strengthened to enhance the electro-luminescence efficiency of silicon so as to accomplish the lasing effect.
