Abstract: <P>PROBLEM TO BE SOLVED: To prevent the occurrence of particles by a wafer bevel portion and a W film reaching the rear face when forming the tungsten film W by chemical vapor deposition method wherein SiH<SB>4</SB>and WF<SB>6</SB>are alternately supplied.  <P>SOLUTION: On top of a semiconductor substrate 102 including an opening which reaches an interconnection in a lower layer, a TiN/Ti adhesion layer 103 is deposited by CVD (chemical vapor deposition) method. In CVD growth of W, after a first W film 104 is grown by chemical vapor deposition method where SiH<SB>4</SB>and WF<SB>6</SB>are alternately supplied, a second W film 106 is formed on top of the first W film by hydrogen reduction of WF<SB>6</SB>to fill up the opening. Then, after removing the W film grown on the bevel portion and on the rear face using sulfuric acid and hydrogen peroxide, excessive W/TiN/Ti film is removed by CMP (chemical mechanical polishing) to form a W plug.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
