    • PURPOSE: A semiconductor device and a manufacturing method thereof are provided to improve carrier mobility by increasing the lower side of strained materials in a source and drain recess cavity near a separation structure. CONSTITUTION: A separation feature is formed on a substrate. A gate stack is formed on the substrate(104). A recess cavity is formed on the substrate(106). The recess cavity is horizontally located between the gate stack and the separation feature. An epitaxial material is formed in the recess cavity(108). The epitaxial material has a corner in the recess cavity. A part of the corner is redistributed in the recess cavity.
