Abstract

A method for manufacturing fins includes following steps. A substrate including a plurality of fins formed thereon is provided. At least an ion implantation is performed to the fins. A thermal process is performed after the ion implantation. An insulating layer is formed on the substrate, and the fins are embedded in the insulating layer. Thereafter, a portion of the insulating layer is removed to form an isolation structure on the substrate, and the fins are exposed from a top surface of the isolation structure. The insulating layer is formed after the ion implantation and the thermal process. Or, the isolation structure is formed before the ion implantation, or between the ion implantation and the thermal process.
