Abstract: A planarization method includes the following steps. A silicon layer is deposited on a substrate, and a top surface of the silicon layer includes a lower portion and a bump portion protruding upwards from the lower portion. An ion bombardment etching process is performed to the silicon layer for reducing a surface step height of the silicon layer. The top surface of the silicon layer is etched by the ion bombardment etching process to become a post-etching top surface, and a distance between a topmost portion of the post-etching top surface and a bottommost portion of the post-etching top surface in a vertical direction is less than a distance between a topmost portion of the bump portion and the lower portion in the vertical direction before the ion bombardment etching process. Subsequently, a chemical mechanical polishing process is performed to the post-etching top surface of the silicon layer.

Abstract: A method for fabricating a semiconductor structure includes forming a plurality of mandrels over a substrate, wherein the substrate comprises a semiconductor substrate as a base. Then, a first dielectric layer is formed to cover on a predetermined mandrel of the mandrels. A second dielectric layer is formed over the substrate to cover the mandrels. The mandrels are removed, wherein a remaining portion of the first dielectric layer and the second dielectric layer at a sidewall of the mandrels remains on the substrate. An anisotropic etching process is performed over the substrate until a top portion of the semiconductor substrate is etched to form a plurality of fins corresponding to the remaining portion of the first dielectric layer and the second dielectric layer.
