Abstract:
A manufacturing method of a semiconductor device is provided to increase a heat flow speed through a seed in a melting process using a laser beam by performing an ion injection process before converting an amorphous silicone film into a single crystal silicone film. A seed film(10) including silicone material is formed by a selective epitaxial growth. An amorphous silicone film including amorphous silicone material is formed on a top of the seed film. The amorphous silicone film is formed by a chemical vapor deposition. A dopant is doped in the amorphous silicone film by performing an ion injection process. A laser beam is irradiated on the amorphous silicone film. The amorphous silicone film is mono-crystallized by the laser beam. A single crystal silicone film(30) is formed through a mono-crystallization of the amorphous silicone film.

Abstract:
A semiconductor device and a fabricating method thereof are provided to prevent a defect portion from being transferred to an upper layer by forming a silicon-germanium protective layer pattern on the defect portion. A first insulation layer pattern(220) is formed on a first single crystal layer(210), and has an opening partially exposing a surface of the first single crystal layer. A seed layer(230) is formed by selective epitaxial growth in a structure to be buried at the opening. A second single crystal layer(250) is formed on the substrate comprising the seed layer by irradiating a laser beam onto a first polycrystal layer. A first protective layer(260) is formed on a defect portion produced when the second single crystal layer is formed. A third single crystal layer(270) is formed on the first protective layer.
