    摘要: In a method of manufacturing a semiconductor device, a plurality of pattern structures disposed on a substrate and having sidewall surfaces extending in a direction perpendicular to a surface of the substrate are provided. An amorphous dielectric layer is formed on at least the sidewall surfaces of the plurality of pattern structures. A plurality of metal particles are distributed on the amorphous dielectric layer. A first crystalline dielectric layer by thermally treating the amorphous dielectric layer using laser light. In thermally treating the amorphous dielectric layer, the laser light is irradiated onto the amorphous dielectric layer from upper sides of the plurality of pattern structures, wherein the irradiated laser light is scattered from the plurality of metal particles.
