Abstract:
A semiconductor device, comprising:a plurality of first gates formed on a semiconductor substrate a first distance apart from each other; a plurality of second gates formed on the semiconductor substrates a second distance, which is larger than said first distance, apart from each other; a first side wall insulating film formed on the side wall of each of said first gates to fill the clearance between adjacent first gates; a second side wall insulating film formed on the side wall of each of said second gates, said second side wall insulating gates being apart from each other; a first diffusion layer formed on the surface of the semiconductor substrate positioned below the first side wall insulating films; a second diffusion layer formed on the surface of the semiconductor substrate positioned between adjacent second side wall insulating films; and a metal silicide compound layer formed on said second diffusion layer and said first and second gates; wherein a portion of said metal silicide compound layer formed on said second diffusion layer and portions of said metal silicide compound layer formed on said first and second gates are formed of the same material.
