Abstract
In a semiconductor device, a source and a drain layers are located in a surface region of a substrate. A source crystal layer is located in a contact region of the source layer to extend to a position higher than the substrate. A drain crystal layer is located in a contact region of the drain layer to extend to a position higher than the substrate. A source contact is located on the source crystal layer. A drain contact is located on the drain crystal layer. A gate width or a gate length extends to a crystal orientation <110> of the substrate. A long side or a major axis of the source crystal layer or a long side or a major axis of the drain crystal layer extends in a direction inclined with respect to the crystal orientation <110> in a planar layout parallel to the surface of the substrate.
