Abstract:
A method of fabricating a semiconductor device, comprising the steps of:forming an amorphous film containing silicon;preparing a catalytic element for promoting crystallization of said silicon;maintaining said catalytic element in contact with at least parts of said amorphous film or introducing said catalytic element into said at least parts of said amorphous film;heat-treating said amorphous film to crystallize portions of said amorphous film that will become active components;preparing a chemical element selected from group 15 of the periodic table;introducing said chemical element into regions adjacent to said portions of said film becoming the active components and simultaneously into regions becoming a lower electrode of each auxiliary capacitor;irradiating a laser light to said film after said introducing step of said chemical element; andheat-treating said film after said irradiating step to getter said catalytic element into regions doped with said chemical element selected from group 15.
