Abstract:
A method provides a gate structure for a plurality of components of a semiconductor device. A silicate layer is provided. In one aspect, the silicate layer is provided on a channel of a CMOS device. A high dielectric constant layer is provided on the silicate layer. The method also includes providing a work function metal layer on the high dielectric constant layer. A low temperature anneal is performed after the high dielectric constant layer is provided. A contact metal layer is provided on the work function metal layer.

Claim (Index 16):
A semiconductor device comprising:\n a substrate; and a plurality of components on the substrate, each of the plurality of components including a source, a drain, a channel and a gate structure, the channel being between the source and drain, the gate structure adjacent to the channel region, the gate structure including a silicate layer, a high dielectric constant layer, a work function metal layer and a contact metal layer, the high dielectric constant layer being between the silicate layer and the work function metal layer, the work function metal layer being between the high dielectric constant layer and the contact metal layer, the silicate layer being closer to the substrate than the high dielectric constant layer, the semiconductor device being exposed only to temperatures of less than one thousand degrees Celsius during and after formation of the gate structure, the plurality of components having a plurality of threshold voltages.
