  • Patent number: 5310446
    Abstract: A method for producing a semiconductor film comprising steps of: preparing a first substrate and a second substrate; superposing the first substrate on the second substrate to form an assembly of combined substrates; applying energy to the assembly of combined substrates to melt a portion within the assembly to form a molten portion therein; cooling the molten portion to crystallize the portion to form a single crystal structure therein; and separating the first substrate from the second substrate. The method makes it possible to control the crystal axis orientation of the recrystallized single crystal structure.

  • Patent number: 4992393
    Abstract: A method for producing a semiconductor thin film by melt and recrystallization process. At least one recess is formed in a stacked layered structure including a semiconductor thin film layer. The recess has an arrow head shape seen from a surface side of the layered structure. The apex of the arrow head shape is oriented to a forward direction on a scanning line. The surface of the layered structure is covered with a cooling medium so that the recess is filled with the cooling medium. An energy beam is irradiated to the layered structure through the cooling medium to scan the structure along the scanning line so as to melt the semiconductor thin film and after that the semiconductor is cooled and recrystallized to form a single crystal structure therein.
