Abstract:
A method for manufacturing a semiconductor device includes providing a semiconductor substrate, forming a high dielectric constant (high-k) gate dielectric layer on the semiconductor substrate, the high-k gate dielectric layer including a nitrided surface that has been subjected to a nitriding treatment or an oxidized surface that has been subjected to an oxidizing treatment, forming a metal gate on the nitrided surface of the high-k gate dielectric layer to form an NMOS transistor, or forming a metal gate on the oxidized surface of the high-k gate dielectric layer to form a PMOS transistor.

Claim (Index 11):
The method of  claim 8 , wherein forming the high-k gate dielectric layer and forming the metal gate comprises:\n depositing a dielectric material layer having a high dielectric constant on the semiconductor substrate; and performing the nitriding treatment on the dielectric material layer to form a nitrided dielectric material layer; forming a first dummy gate of the PMOS transistor and a second dummy gate of the NMOS transistor on the nitrided dielectric material layer; forming a source region and a drain region on opposite sides of the first dummy gate of the PMOS transistor and a source region and a drain region on opposite sides of the second dummy gate of the NMOS transistor; removing the first dummy gate; performing the oxidizing treatment on a first portion of the nitrided dielectric material layer below the removed first dummy gate to form an oxidized first portion of the gate dielectric layer; forming a metal gate on the oxidized first portion of the gate dielectric layer for the PMOS transistor; removing the second dummy gate to expose a second portion of the nitrided dielectric material layer below the removed second dummy gate; forming a metal gate on the exposed second portion of the gate dielectric layer for the NMOS transistor.
