A semiconductor fin includes a channel region. A gate-stressor member, formed of a metal, extends transverse to the fin and includes gate surfaces that straddle the fin in the channel region. The gate-stressor member has a configuration that includes a partial cut spaced from the fin by a cut distance. The configuration causes, through the gate surfaces, a transverse stress in the fin, having a magnitude that corresponds to the cut distance. Transverse stressor members, formed of a metal, straddle the fin at regions outside of the channel region and cause, at the regions outside of the channel region, additional transverse stresses in the fin. The magnitude that corresponds to the cut distance, in combination with the additional transverse stresses, induces a longitudinal compressive strain in the channel region.
