A method for manufacturing a semiconductor device includes forming a fin structure having a top face and a first side face and a second side face opposite to the first side face, forming a lower cover layer over the first and second side faces, forming an upper cover layer over the first and second side faces, the upper cover layer being spaced apart from the lower cover layer so that exposed regions of the first and second side faces are formed between the lower cover layer and the upper cover layer, and forming first and second semiconductor layers over the exposed regions of the first and second side faces, respectively. |
