    摘要: An integrated circuit structure includes a substrate having a first portion in a first device region and a second portion in a second device region; and two insulation regions in the first device region and over the substrate. The two insulation regions include a first dielectric material having a first k value. A semiconductor strip is between and adjoining the two insulation regions, with a top portion of the semiconductor strip forming a semiconductor fin over top surfaces of the two insulation regions. An additional insulation region is in the second device region and over the substrate. The additional insulation region includes a second dielectric material having a second k value greater than the first k value.

    摘要: An integrated circuit structure includes a substrate and a fin field-effect transistor (FinFET). The FinFET includes a fin over the substrate and having a first fin portion and a second fin portion. A gate stack is formed on a top surface and sidewalls of the first fin portion. An epitaxial semiconductor layer has a first portion formed directly over the second fin portion, and a second portion formed on sidewalls of the second fin portion. A silicide layer is formed on the epitaxial semiconductor layer. A peripheral ratio of a total length of an effective silicide peripheral of the FinFET to a total length of a fin peripheral of the FinFET is greater than 1.
