  • Semiconductor device having a dual gate electrode and methods of making the same
    Patent number: 8076729
    Abstract: Disclosed is a method for forming a dual gate electrode of a semiconductor device, which may improve manufacturing productivity by simplifying a process of forming gate electrodes in PMOS and NMOS regions, respectively, and may provide improvement in performance by making the two gate electrodes have a different thickness and material state in a manner that one of the two gate electrodes has a single-layer structure and the other one has a two-layer structure.
