Abstract:
A semiconductor device includes a first field effect transistor (FET) including a first gate dielectric layer and a first gate electrode. The first gate electrode includes a first lower metal layer and a first upper metal layer. The first lower metal layer includes a first underlying metal layer in contact with the first gate dielectric layer and a first bulk metal layer. A bottom of the first upper metal layer is in contact with an upper surface of the first underlying metal layer and an upper surface of the first bulk metal layer.

Claim (Index 21):
A method of manufacturing a semiconductor device, the method comprising:\n forming a dummy gate structure over a substrate, the dummy gate structure including a dummy gate dielectric layer, a dummy gate electrode layer and sidewall spacers; forming an etching stop layer over the dummy gate structure; forming a first interlayer dielectric (ILD) layer over the etching stop layer; forming a gate space by removing the dummy gate electrode layer and the dummy gate dielectric layer; forming a gate dielectric layer in the gate space and over upper portions of the first ILD layer, the etching stop layer and the sidewall spacers; forming one or more metal layers over the gate dielectric layer; forming a gate recess by removing an upper portion of the one or more metal layers; forming a second metal layer on a top of the first metal layer, from which the upper portion has been removed, in the gate recess; and forming a cap insulating layer over the second metal layer in the gate recess, wherein: the cap insulating layer is in contact with the gate dielectric layer, and when the one or more metal layers are formed, the gate dielectric layer formed over upper portions of the first ILD layer, the etching stop layer and the sidewall spacers is removed.
