    摘要: A fin field effect transistor including a first insulation region and a second insulation region over a top surface of a substrate. The first insulation region includes tapered top surfaces, and the second insulation region includes tapered top surfaces. The fin field effect transistor further includes a fin extending above the top surface between the first insulation region and the second insulation region. The fin includes a first portion having a top surface below the tapered top surfaces of the first insulation region. The fin includes a second portion having a top surface above the tapered top surfaces of the first insulation region.

    摘要: A FinFET is described, the FinFET includes a substrate including a top surface and a first insulation region and a second insulation region over the substrate top surface comprising tapered top surfaces. The FinFET further includes a fin of the substrate extending above the substrate top surface between the first and second insulation regions, wherein the fin includes a recessed portion having a top surface lower than the tapered top surfaces of the first and second insulation regions, wherein the fin includes a non-recessed portion having a top surface higher than the tapered top surfaces. The FinFET further includes a gate stack over the non-recessed portion of the fin.
