Abstract:
A method of controlling NFET and PFET gate heights across different gate widths with chamfering and the resulting device are provided. Embodiments include forming an ILD over a fin; forming cavities in the ILD, each with similar or different widths; forming a high-K dielectric layer over the ILD and in each cavity; forming a pWF metal layer over the dielectric layer in one cavity; recessing the pWF metal layer to a height above the fin; forming an nWF metal layer in the cavities over the dielectric and pWF metal layers; recessing the nWF metal layer to a height above the pWF metal layer; forming a barrier layer over the dielectric and nWF metal layers; filling the cavities with a low-resistive metal; and recessing the barrier and dielectric layers to a height above the nWF metal layer; and concurrently etching the low-resistive metal.

Claim (Index 1):
A device comprising:\n an interlayer dielectric (ILD) over a silicon (Si) fin; first and second cavities in the ILD, each over and perpendicular to the Si fin; a high-K dielectric layer on side and bottom surfaces of the first and second cavities; a p-type work function (pWF) metal layer over the high-K dielectric layer in the first and second cavities; an n-type work function (nWF) metal layer over the pWF metal layer and over edges of the pWF metal layer in the first cavity and over the high-K dielectric layer in the second cavity; a barrier metal layer over the nWF metal layer and over edges of the nWF layer, wherein the first and second cavities comprise a low-resistive metal filling with a bump at a center of each cavity.
