Abstract
A fin-type field-effect transistor (FinFET) device includes a plurality of fins formed over a substrate. The semiconductor device further includes a dielectric layer filled in a space between each fin and over a first portion of the plurality of fins and a dielectric trench formed in the dielectric layer. The dielectric trench has a vertical profile. The semiconductor device further includes a second portion of the plurality of fins recessed and exposed in the dielectric trench. The second portion of the plurality of fins have a rounded-convex-shape top profile.
