Abstract The invention provides a method for making semiconductor device. A CMOS transistor and a memory cell transistor are formed without causing deterioration to reliability and performance. A step of covering a memory cell region with an HTO film and forming sidewalls in the CMOS transistor while exposing a diffusion region of the CMOS transistor, a step of depositing titanium, and a step of reacting the diffusion region with the titanium, forming a titanium silicide in the CMOS, transistor source and drain are provided.
