Title: Semiconductor device with high-melting-point silicide and its manufacture
Inventor: SUENAGA ATSUSHI
IPC: H01L21/266
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To simultaneously form a low-resistance diffusion layer and a high- resistance diffusion layer regardless of the formation of a high-melting-point metal silicide by increasing the resistance of silicide film formed at a protection circuit part. SOLUTION: In a semiconductor device where high-melting-point silicides 22a and 22b are formed on the surface of diffused layers 16 and 18, the structure of the first diffused layer 16 formed on a same semiconductor substrate 2 differs from that of the second diffusion layer 18. The first diffused layer 16 is the source/drain region of a MOS transistor which becomes, for example, a protective circuit and the second diffused layer 18 is the source/drain region of the MOS transistor, for example, for a memory cell circuit other than the protection circuit. The impurity concentration on the surface of the first diffused layer 16 is set higher than that on the surface of the second diffused layer 18.  By setting the impurity concentration on the surface of the diffused layer 16 higher, the silicide reaction of a high-melting-point metal formed on the surface becomes insufficient, thus preventing resistance from decreasing and causing it from increasing.
