Patent ID: 8692330

Claim:
A semiconductor device comprising: a semiconductor layer of a first general conductivity type; an element isolation insulation film isolating the semiconductor layer; a well layer of a second general conductivity type formed in a surface portion of the semiconductor layer; a plurality of body layers of the second general conductivity type formed in a surface portion of the well layer so as to extend parallel with each other in a first direction; a plurality of source layers of the first general conductivity type and a plurality of drain layers of the first general conductivity type which are formed in surface portions of corresponding body layers so that the source layers and the drain layers extend in the first direction and alternate in a second direction perpendicular to the first direction; a contact layer of the second general conductivity type formed in a surface portion of the well layer and a surface portion of the body layer adjacent the element isolation insulation film, the contact layer surrounding the source layers and the drain layers; a gate electrode formed on the body layer and the well layer and extending in the first direction between the source layers and the drain layers; metal silicide layers formed in surface portions of the source layers, in surface portions of the drain layers, and in surface portions of a portion of the contact layer that extends in the second direction, no metal silicide layer being formed in a surface portion of a portion of the contact layer that extends in the first direction; and a finger form source electrode, a finger form drain electrode, and a contact electrode surrounding the source and drain electrodes, each of the source, drain and contact electrodes being connected to the metal silicide layers through contact holes formed in an interlayer insulation film deposited on the metal silicide layers.
