| abstract |
The present invention promotes incorporation of nitrogen (e.g., nitridation) into high-k dielectric films using a low temperature process. Further, the present invention provides an in-situ method; that is formation of the high-k dielectric film and nitridation of the film are carried out in the same process chamber during deposition of the film, as opposed to the conventional post processing techniques. In another aspect, a method for depositing a multi-layer material for use as a gate dielectric layer in semiconductor devices is provided. |
