    摘要: A tight contact layer is disposed on a semiconductor substrate, the tight contact layer being made of one material selected from the group consisting of refractory metal, alloy of refractory metal, nitride of refractory metal, and siliconized nitride of refractory metal. An oxide surface layer is disposed on the surface of the tight contact layer, the oxide surface layer being made of oxide of material constituting the tight contact layer. A first conductive layer is disposed on the surface of the oxide surface layer, the first conductive layer being made of a platinum group or alloy which contains a platinum group. When a conductive layer made of metal such as a platinum group is formed on a tight contact layer, coverage and morphology can be prevented from being degraded.

    摘要: Under a sidewall formed over a side wall of a gate electrode, a low-concentration LDD region and a high-concentration LDD region which is extremely shallow and apart from a region under the gate electrode are formed. Further, a source/drain region is formed outside these LDD regions. Since the extremely shallow high-concentration LDD region is formed under the sidewall, even if hot carriers are accumulated in the sidewall, depletion due to the hot carriers can be suppressed. Further, since the high-concentration LDD region is formed apart from a region under the gate electrode, a transverse electric field in the channel is sufficiently relaxed, so that characteristic deterioration due to a threshold shift can be suppressed.
