  • FinFET structure with multiple workfunctions and method for fabricating the same
    Patent number: 8835233
    Abstract: A method for fabricating a multiple-workfunction FinFET structure includes depositing a first workfunction material in a layer in a plurality of trenches of the FinFET structure and etching the first workfunction material layer so as to completely remove the first workfunction material layer from all but a first trench of the plurality of trenches. Further, the method includes depositing a second workfunction material in a layer in the plurality of trenches and etching the second workfunction material layer so as to completely remove the second workfunction material layer from all but a second trench of the plurality of trenches. Still further, the method includes depositing a third workfunction material in a layer in the plurality of trenches.
