Classification: CPC H | IPC H

Claim 8:
9. A method of forming a semiconductor structure, the method comprising:
forming a first silicon oxide layer overlying a semiconductor substrate;
forming a first amorphous silicon layer overlying the first silicon oxide layer;
forming a silicon nitride layer overlying the first amorphous silicon layer;
forming a second amorphous silicon layer overlying the silicon nitride layer;
forming a second silicon oxide layer overlying the second amorphous silicon removing the silicon nitride layer;
flowing a gaseous metal-containing precursor to contact the first amorphous silicon layer and the second amorphous silicon layer; and
thermally activating a conversion reaction at greater 300 C to exchange silicon in the first amorphous silicon layer and the second amorphous silicon layer with a metal material from the gaseous metal-containing precursor to form a layer of transitional metal.
