摘要: A thin film-forming method according to the present invention is characterized by comprising the steps of introducing TiCl.sub.4, hydrogen, nitrogen and NF.sub.3 into a film-forming chamber containing a semiconductor substrate (1) having a groove made in its surface, after the chamber has been evacuated to 10.sup.-4 Torr or less; and converting these gases into plasma, thereby forming a thin TiN film on only that portion of the groove which is other than the wall surfaces of the groove.
