Abstract

A device includes an epitaxy structure having a recess therein, a dielectric layer over the epitaxy structure, the dielectric layer having a contact hole communicating with the recess, a dielectric spacer liner (DSL) layer on a sidewall of the recess, a barrier layer on the DSL layer, and a conductor. The DSL layer has an opening. The DSL layer extends further into the epitaxy structure than the barrier layer. The conductor is disposed in the contact hole and electrically connected to the epitaxy feature through the opening of the DSL layer.
