ABSTRACT:
A heat treatment for diffusing impurity ions implanted into a silicon layer is performed at a heat treatment temperature which is less than an aggregation temperature of the silicon layer. A thermal aggregation of the silicon layer can be inhibited, thereby reducing a silicon deficiency of the silicon layer.
