    Abstract: A fin-shaped structure includes a substrate having a first fin-shaped structure located in a first area and a second fin-shaped structure located in a second area, wherein the second fin-shaped structure includes a ladder-shaped cross-sectional profile part. The present invention also provides two methods of forming this fin-shaped structure. In one case, a substrate having a first fin-shaped structure and a second fin-shaped structure is provided. A treatment process is performed to modify an external surface of the top of the second fin-shaped structure, thereby forming a modified part. A removing process is performed to remove the modified part through a high removing selectivity to the first fin-shaped structure and the second fin-shaped structure, and the modified part, thereby the second fin-shaped structure having a ladder-shaped cross-sectional profile part is formed.

    Abstract: A method for fabricating a semiconductor device is described. A semiconductor substrate is provided, wherein the substrate has a first area and a second area. A first gate structure and a second gate structure are formed over the substrate in the first area and the substrate in the second area, respectively. A first spacer is framed on the sidewall of each gate structure. At least one etching process including at least one wet etching process is performed. The first spacer is removed. A second spacer is formed on the sidewall of each gate structure. A mask layer is formed in the second area. Ion implantation is formed using the mask layer, the first gate structure and the second spacer as a mask to form S/D extensions in the substrate beside the first gate structure in the first area. The mask layer is then removed.
