    Abstract: A semiconductor device includes a fin structure disposed over a substrate, a gate structure and a source. The fin structure includes an upper layer being exposed from an isolation insulating layer. The gate structure disposed over part of the upper layer of the fin structure. The source includes the upper layer of the fin structure not covered by the gate structure. The upper layer of the fin structure of the source is covered by a crystal semiconductor layer. The crystal semiconductor layer is covered by a silicide layer formed by Si and a first metal element. The silicide layer is covered by a first metal layer. A second metal layer made of the first metal element is disposed between the first metal layer and the isolation insulating layer.
