Method of producing monocrystalline semiconductor material, particularly
silicon, with adjustable dislocation density
摘要:
A method for obtaining a homogeneous dislocation density in a semiconductor rod, by first subjecting the semiconductor rod in a known manner, to a crucible-free zone melting process whereby it becomes monocrystalline and free of dislocations, and thereafter an annealing zone is moved through the rod, under specified conditions.
