Abstract
Forming metal gate transistors that have different work functions is disclosed. In one example, a first metal, which is a 'mid gap' metal, is manipulated in first and second regions by second and third metals, respectively, to move the work function of the first metal in opposite directions in the different regions. The resulting work functions in the different regions correspond to that of different types of the transistors that are to be formed.
