Abstract:
A method of manufacturing a field effect transistor using a gate last process includes providing the field effect transistor which includes a high-k dielectric formed between an elevated source and an elevated drain and surrounding a metal gate, and performing a chemical mechanical planarization (CMP) process on an upper surface of the elevated source, and in which a height of the metal gate becomes lower than a height of the elevated source according to the CMP process.

Claim (Index 1):
A method of manufacturing a Fin Field Effect Transistor (FinFET), the method comprising:\n providing a substrate; forming an elevated source and an elevated drain on the substrate; forming a first dielectric layer on the substrate, the first dielectric layer including a gate oxide layer and a high-k dielectric layer disposed on the gate oxide layer, the high-k dielectric layer being U-shaped; forming a metal buffer layer on the first dielectric layer, the metal buffer layer being U-shaped; forming a metal gate on the metal buffer layer, the metal gate contacting the metal buffer layer; and forming a second dielectric layer on the substrate, the second dielectric layer contacting the first dielectric layer, wherein\n a dielectric constant of the second dielectric layer is less than that of the first dielectric layer, and \n a first portion of the first dielectric layer is disposed between the metal buffer layer and the second dielectric layer, and blocks the metal buffer layer to contact the second dielectric layer.
