  • Patent number: 7999325
    Abstract: An example process to remove spacers from the gate of a NMOS transistor. A stress creating layer is formed over the NMOS and PMOS transistors and the substrate. In an embodiment, the spacers on gate are removed so that stress layer is closer to the channel of the device. The stress creating layer is preferably a tensile nitride layer. The stress creating layer is preferably a contact etch stop liner layer. In an embodiment, the gates, source and drain region have a silicide layer thereover before the stress creating layer is formed. The embodiment improves the performance of the NMOS transistors.

  • Publication number: 20100059831
    Abstract: A first example embodiment provides a method of removing first spacers from gates and incorporating a low-k material into the ILD layer to increase device performance. A second example embodiment comprises replacing the first spacers after silicidation with low-k spacers. This serves to reduce the parasitic capacitances. Also, by implementing the low-k spacers only after silicidation, the embodiments' low-k spacers are not compromised by multiple high dose ion implantations and resist strip steps. The example embodiments can improve device performance, such as the performance of a rim oscillator.

  • Publication number: 20090233444
    Abstract: A polishing process in a semiconductor device fabrication process employs a polishing composition in which a gaseous phase is created within the polishing composition. During a polishing process, the gaseous phase dynamically responds to changes in the surface profile of the material undergoing removal by chemical and abrasive action during polishing. The inert gas bubble density dynamically increases in proximity to surface region of the substrate being polished that are prone to dishing and erosion. The increased inert gas bubble density operates to reduce the polish removal rate relative to other regions of the substrate. The dynamic action of the gaseous phase within the polishing composition functions to selectively reduce the localized polish removal rate such that a uniformly smooth and flat polished surface is obtained that is independent of the influence of pattern density during the polishing process.
