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 fin field effect transistor (FinFET) including a first insulation region and a second insulation region and fin there between. A gate stack is disposed over a first portion of the fin. A strained source/drain material is disposed over a second portion of the fin. The strained source/drain material has a flat top surface extending over the first and second insulation regions. The first insulation region may include a tapered top surface.
