Abstract:
Integrated circuits and methods for fabricating integrated circuits are provided herein. In an embodiment of a method for fabricating integrated circuits, a P-type gate electrode structure and an N-type gate electrode structure are formed overlying a semiconductor substrate. The gate electrode structures each include a gate electrode that overlies a gate dielectric layer and a nitride cap that overlies the gate electrode. Conductivity determining ions are implanted into the semiconductor substrate using the P-type gate electrode structure and the N-type gate electrode structure as masks to form a source region and a drain region for the P-type gate electrode structure and the N-type gate electrode structure. The nitride cap remains overlying the N-type gate electrode structure during implantation of the conductivity determining ions into the semiconductor substrate to form the source region and the drain region for the N-type gate electrode structure.

Abstract:
When forming transistors with deuterium enhanced gate dielectrics and strained channel regions, the manufacturing processes of strain-inducing dielectric material layers formed above the transistors may be employed to efficiently introduce and diffuse the deuterium to the gate dielectrics. The incorporation of deuterium into the strain-inducing dielectric material layers may be accomplished on the basis of a deposition process in which deuterium is present in the process environment during deposition. The process temperature of the deposition process may be chosen to perform—in combination with further subsequently performed process steps—a sufficient diffusion of deuterium to the gate dielectrics.
