Abstract:
A method of manufacturing a semiconductor device, comprising:forming an insulating film over a semiconductor wafer; subjecting the insulating film to photolithography and etching to thereby define a contact hole in the insulating film; forming an adhesive layer over the insulating film and in the contact hole defined therein; placing the semiconductor wafer in an interior of a processing chamber under an atmosphere including no oxygen and subjecting the adhesive layer to heat treatment; setting a temperature of the semiconductor wafer to less than or equal to a temperature equivalent to energy of such an extent as to cut bonding between atoms which form the adhesive layer, and thereafter taking the semiconductor wafer out of the processing chamber; and forming an embedding film that is embedded in the contact hole, wherein the adhesive layer comprises titanium, titanium nitride or a film obtained by stacking the titanium and titanium nitride on each other, and said taking the semiconductor wafer out of the processing chamber is executed at 80Â° C. or less.
