Abstract:
1. A semiconductor device having a MISFET, comprising: a silicon substrate; a channel region of said MISFET in said silicon substrate; a gate insulating film on said channel region; a gate electrode overlying said channel region with said gate insulating film being sandwiched therebetween; a pair of spaced-apart source and drain regions interposing said channel region therebetween; and a plurality of nickel silicide regions making up part of said source and drain regions of said MISFET, said nickel silicide regions being provided on silicon surfaces having Si{110} crystal planes in said source and drain regions, and the each nickel silicide region containing a rectangular planar shape having long sides laying perpendicular to a Si<100> direction on said silicon surface and short sides being parallel to the Si<100> direction and having a width of 0.5 μm or less.
