Abstract: A gate electrode including a polycrystalline silicon film and a sidewall insulating film are formed on a semiconductor substrate with a gate insulating film therebetween. The semiconductor substrate provided with the gate electrode is brought into contact with a predetermined plating solution to deposit a cobalt film on the semiconductor substrate by electroless plating. Then, a heat treatment is effect to cause a reaction between the silicon in the gate electrode and the cobalt as well as a reaction between the silicon in the semiconductor substrate and the cobalt to form a cobalt silicide film. Thereafter, the unreacted cobalt film is removed. Thereby, damage to the semiconductor substrate can be suppressed, and salicide process can be simplified.

Abstract: Disclosed is a method for removing Pt (or Pt—Ir) and BST contaminants on the surface edge, back, and bevel of a semiconductor wafer. A wafer on which a stacked film selected from the group of a Pt film, a Pt—Ir film, and a Ba—Sr—Ti film is formed is prepared. A chemical containing hydrochloric acid is applied only to the surface edge, back, and bevel of the wafer. The surface edge, back, and bevel of the wafer are rinsed with pure water. Further, a chemical containing hydrogen fluoride is applied. The surface edge, back, and bevel of the wafer are rinsed again with pure water.
