Method of manufacturing semiconductor devices using a crystallization promoting material

摘要

In a method of manufacturing a semiconductor device, an insulating film having an opening is formed on an amorphous film 103 containing silicon therein. After catalytic elements are introduced from the opening, the amorphous film 103 is crystallized. Thereafter elements (phosphorus) selected from Group XV are introduced from the opening, and then a heat treatment is conducted to obtain a film having crystallinity. Thereafter, a portion of the film containing silicon into which the catalytic elements and phosphorus is introduced are removed.
