Abstract: A titanium silicide film (4) is formed on an Si wafer (1). First, an Si wafer (1) is processed by plasma using high frequency wave. Next, a Ti-containing material gas is supplied onto the plasma-processed Si-containing portion to generate plasma and form a Ti film, and a titanium silicide film (4) is formed by the reaction between the formed Ti film and Si in the Si-containing portion. The Si wafer (1) is plasma-processed while a DC bias voltage (Vdc) of at least 200 V in absolute value is being applied to the Si wafer (1).
