  • Patent number: 9082876
    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.

  • Patent number: 9076818
    Abstract: A method for fabricating a semiconductor device includes forming first and second gate structures overlying the semiconductor substrate, and depositing a layer of a silicide-resistant material over the first and second gate structures and over the semiconductor substrate. The method further includes forming sidewall spacers from the layer of silicide-resistant material adjacent the first gate structure and removing the silicide-resistant material adjacent the sidewall spacers to expose the silicon substrate in a source and drain region. Still further, the method includes implanting conductivity determining impurities in the source and drain region, depositing a silicide forming metal, and annealing the semiconductor device to form a silicide in the source and drain region. The silicide-resistant material is not removed from over the second gate structure so as to prevent silicide formation at the second gate structure.

  • Patent number: 8939765
    Abstract: In sophisticated semiconductor devices, the defect rate that may typically be associated with the provision of a silicon/germanium material in the active region of P-channel transistors may be significantly decreased by incorporating a carbon species prior to or during the selective epitaxial growth of the silicon/germanium material. In some embodiments, the carbon species may be incorporated during the selective growth process, while in other cases an ion implantation process may be used. In this case, superior strain conditions may also be obtained in N-channel transistors.

  • Publication number: 20150021693
    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.
