Abstract:
A method for forming a semiconductor device structure having a RuSixOy adhesion layer, the method comprising:(a) placing a semiconductor substrate assembly in a reaction chamber, said semiconductor substrate assembly having a surface; (b) introducing C6H8Ru(CO)3 into said reaction chamber to form a single layer of ruthenium on at least a portion of said semiconductor substrate assembly surface; (c) introducing a non-reactive gas into said reaction chamber to substantially cover said single layer of ruthenium and purge said C6H8Ru(CO)3 from said reaction chamber; (d) introducing a silicon precursor into said reaction chamber to form a single layer of RuSixOy on at least a portion of said semiconductor substrate assembly surface; and (e) introducing said non-reactive gas into said reaction chamber to substantially cover said single layer of RuSixOy and purge said silicon precursor from said reaction chamber.
