Abstract: An integrated circuit includes a semiconductor substrate, a gate dielectric over the substrate, a metal gate structure over the semiconductor substrate and the gate dielectric, a dielectric film on the metal gate structure, the dielectric film comprising oxynitride combined with metal from the metal gate, and an interlayer dielectric (ILD) on either side of the metal gate structure.

Abstract: A device including a gate stack over a semiconductor substrate having a pair of spacers abutting sidewalls of the gate stack. A recess is formed in the semiconductor substrate adjacent the gate stack. The recess has a first profile having substantially vertical sidewalls and a second profile contiguous with and below the first profile. The first and second profiles provide a bottle-neck shaped profile of the recess in the semiconductor substrate, the second profile having a greater width within the semiconductor substrate than the first profile. The recess is filled with a semiconductor material. A pair of spacers are disposed overly the semiconductor substrate adjacent the recess.

Abstract: The present disclosure provides a method for fabricating a semiconductor device that includes providing a silicon substrate, forming a gate stack over the silicon substrate, performing a biased dry etching process to the substrate to remove a portion of the silicon substrate, thereby forming a recess region in the silicon substrate, performing a non-biased etching process to the recess region in the silicon substrate, thereby forming a bottle-neck shaped recess region in the silicon substrate, and epi-growing a semiconductor material in the bottle-neck shaped recess region in the silicon substrate. An embodiment may include a biased dry etching process including adding HeO2 gas and HBr gas. An embodiment may include performing a first biased dry etching process including N2 gas and performing a second biased dry etching process not including N2 gas.

Abstract: A method of making an integrated circuit includes providing a semiconductor substrate and forming a gate dielectric over the substrate, such as a high-k dielectric. A metal gate structure is formed over the semiconductor substrate and the gate dielectric and a thin dielectric film is formed over that.

Abstract: Gas distribution systems for deposition processes and methods of using the same. A substrate support member holding a substrate is disposed in a processing chamber. A plurality of first and second gas nozzles is connected to a gas distribution ring disposed in the processing chamber. The first gas nozzles provide a first reactant gas and include at least first and second outlet apertures. The second gas nozzles provide a second reactant gas and include third outlet apertures. The first outlet aperture is larger than the second outlet aperture, such that the first gas nozzle with the first outlet aperture creates an increased gas flow adjacent to a determined portion of the substrate to increase deposition from the first reactant gas on the determined portion of the substrate.
