    摘要: A semiconductor structure includes a semiconductor substrate having a first portion and a second portion. A first Fin field-effect transistor (FinFET) is formed over the first portion of the semiconductor substrate, wherein the first FinFET includes a first fin having a first fin height. A second FinFET is formed over the second portion of the semiconductor substrate, wherein the second FinFET includes a second fin having a second fin height different from the first fin height. A top surface of the first fin is substantially level with a top surface of the second fin. A punch-through stopper is underlying and adjoining the first FinFET, wherein the punch-through stopper isolates the first fin from the first portion of the semiconductor substrate.
