发明名称 Method of manufacturing semiconductor device having pre-silicide nitrogen implant
摘要 According to one embodiment, a method of manufacturing a semiconductor device which includes a MISFET, includes: forming a gate insulating film on a semiconductor substrate; forming a gate electrode on the gate insulating film; implanting nitrogen equal to or more than 5.0e14 atoms/cm2 and equal to or less than 1.5e15 atoms/cm2 in the semiconductor substrate by tilted ion implantation in a direction from an outside to an inside with respect to side surfaces of the gate electrode; depositing a metal film including nickel on areas in which nitrogen atoms are implanted, the areas are in a semiconductor substrate on both sides of the gate electrode; and performing first heat processing of reacting the metal film and the semiconductor substrate and forming metal semiconductor compound layers, the shapes of the layers are controlled by the nitrogen profiles of the areas.
