Abstract: A method of making a semiconductor device includes a substrate having a semiconductor layer having a first portion for non-volatile memory and a second portion exclusive of the first portion. A first dielectric layer is formed on the semiconductor layer. A plasma nitridation is performed on the first dielectric layer. A first plurality of nanoclusters is formed over the first portion and a second plurality of nanoclusters over the second portion. The second plurality of nanoclusters is removed. A second dielectric layer is formed over the semiconductor layer. A conductive layer is formed over the second dielectric layer.

A first dielectric layer is formed over the semiconductor layer. A first plurality of nanoclusters is formed over the first portion and a second plurality of nanoclusters is formed over the second portion. A layer of nitrided oxide is formed around each nanocluster of the first plurality and the second plurality of nanoclusters. Remote plasma nitridation is performed on the layers of nitrided oxide of the first plurality of nanoclusters. The nanoclusters are removed from the second portion. A second dielectric layer is formed over the semiconductor layer. A conductive layer is formed over the second dielectric layer.

Abstract: A method for providing gates of transistors with at least two different work functions utilizes a silicidation of two different metals at different times, silicidation for one gate and polysilicon for the other, or silicidation using a single metal with two differently doped silicon structures. Thus the problem associated with performing silicidation of two different metals at the same time is avoided. If the two metals have significantly different silicidation temperatures, the one with the lower temperature silicidation will likely have significantly degraded performance as a result of having to also experience the higher temperature required to achieve silicidation with the other metal.
