Abstract: A method of fabricating a gate cap layer includes providing a substrate with an interlayer dielectric disposed thereon, wherein a recess is disposed in the interlayer dielectric and a metal gate fills in a lower portion of the recess. Later, a cap material layer is formed to cover the interlayer dielectric and fill in an upper portion of the recess.
