  • Patent number: 8860150
    Abstract: The metal gate structure of the present invention can include a TiN complex, and the N/Ti proportion of the TiN complex is decreased from bottom to top. In one embodiment, the TiN complex can include a single TiN layer, which has an N/Ti proportion gradually decreasing from bottom to top. In another embodiment, the TiN complex can include a plurality of TiN layers stacking together. In such a case, the lowest TiN layer has a higher N/Ti proportion than the adjusted TiN layer.
