| titleOfInvention | Semiconductor device and manufacturing method thereof |
| abstract | Semiconductor device manufacturing includes forming fins over substrate extending in first direction. Gate is formed over fin's first portion, gate extends in second direction crossing first. Fin mask layer formed on fin sidewalls. Fin second portions are recessed, wherein second portions are located on opposing gate sides. Epitaxial source/drains are formed over recessed fins. Epitaxial source/drain structures include first layer having first dopant concentration, second layer having second dopant concentration, and third layer having third dopant concentration. Third concentration is greater than second concentration, second concentration is greater than first concentration. At least adjacent third layers source/drains merge thereby form merged source/drains, and height in third direction substantially perpendicular to first and second directions from upper surface of adjacent fins to merged source/drain lower surface uppermost point is greater than thickness of merged source/drain in third direction from lower surface uppermost point of source/drain to source/drain top surface. |
