Abstract
An impurity doping system is disclosed, which includes an impurity doping device for doping an impurity into a surface of a solid state base body, a measuring device for measuring an optical characteristic of an area into which the impurity is doped, and an annealing device for annealing the area into which the impurity is doped. The impurity doping system realizes an impurity doping not to bring about a rise of a substrate temperature, and measures optically physical properties of a lattice defect generated by the impurity doping step to control such that subsequent steps are optimized.
