Abstract

A gate having sidewalls is formed on an integrated circuit substrate. A barrier layer spacer is formed on the sidewalls of the gate. A portion of the barrier layer spacer protrudes from the sidewalls of the gate exposing a lower surface of the barrier layer spacer that faces the integrated circuit substrate. A silicide layer is formed on the portion of the barrier layer spacer protruding from the sidewalls of the gate. Related devices are also provided.
