Semiconductor devices and methods of manufacture are disclosed. A representative transistor device includes two fins over a workpiece. An insulating material is over the fins. The insulating material is not disposed between the fins. A dielectric material is over sidewalls of the insulating material and over a portion of the workpiece between the fins. A gate is over the dielectric material. The gate includes a first conductive material and a second conductive material over the first conductive material. The second conductive material is recessed below a top surface of the insulating material. The second conductive material has a top surface with a rounded profile.
