Abstract:
A structure, design structure and method of manufacturing is provided for a dual metal gate Vt roll-up structure, e.g., multi-work function metal gate. The multi-work function metal gate structure comprises a first type of metal with a first work function in a central region and a second type of metal with a second work function in at least one edge region adjacent the central region. The first work-function is different from the second work function.
