Abstract:
A method for forming a semiconductor device and a semiconductor device formed by the method are disclosed. In an embodiment, the method includes depositing a dummy dielectric layer on a fin extending from a substrate; depositing a dummy gate seed layer on the dummy dielectric layer; reflowing the dummy gate seed layer; etching the dummy gate seed layer; and selectively depositing a dummy gate material over the dummy gate seed layer, the dummy gate material and the dummy gate seed layer constituting a dummy gate.
