Abstract: A method of removing a hard mask on a gate includes forming a first gate structure and a second gate structure. The first gate structure includes a first gate, a first hard mask disposed on the first gate and a first spacer surrounding the first gate and the first hard mask, wherein the second gate structure includes a second gate, a second hard mask disposed on the second gate and a second spacer surrounding the second gate and the second hard mask. Later, the first spacer surrounding the first hard mask and the second spacer surrounding the second hard mask are removed. After that, a dielectric layer is formed to cover the first hard mask and the second hard mask. Finally, the second dielectric layer, the first mask layer and the second mask layer are removed.

Abstract: A fin structure cutting process includes the following steps. Four fin structures are formed in a substrate, where the four fin structures including a first fin structure, a second fin structure, a third fin structure and a fourth fin structure are arranged sequentially and parallel to each other. A first fin structure cutting process is performed to remove top parts of the second fin structure and the third fin structure, thereby a first bump being formed from the second fin structure, and a second bump being formed from the third fin structure. A second fin structure cutting process is performed to remove the second bump and the fourth fin structure completely, but to preserve the first bump beside the first fin structure. Moreover, the present invention provides a fin structure formed by said process.
