ABSTRACT:
Silicon raw material and gallium dopant are charged and mixed in a crucible. The silicon raw material is heated to a predetermined temperature, and melted under an inactive gas atmosphere. The melted silicon raw material is cooled down to be crystallized to make a polycrystalline silicon incorporating the gallium dopant.
