  • 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.
