Abstract: A finFET device includes a doped source and/or drain extension that is disposed between a gate spacer of the finFET and a bulk semiconductor portion of the semiconductor substrate on which the n-doped or p-doped source or drain extension is disposed. The doped source or drain extension is formed by a selective epitaxial growth (SEG) process in a cavity formed proximate the gate spacer. After formation of the cavity, advanced processing controls (APC) (i.e., integrated metrology) is used to determine the distance of recess, without exposing the substrate to an oxidizing environment. The isotropic etch process, the metrology, and selective epitaxial growth may be performed in the same platform.

Abstract: Embodiments of the present invention pertain to methods of forming features on a substrate using a self-aligned triple patterning (SATP) process. A stack of layers is patterned near the optical resolution of a photolithography system using a high-resolution photomask. The heterogeneous stacks are selectively etched to undercut a hard mask layer beneath overlying cores. A dielectric layer, which is flowable during formation, is deposited and fills the undercut regions as well as the regions between the heterogeneous stacks. The dielectric layer is anisotropically etched and a conformal spacer is deposited on and between the cores. The spacer is anisotropically etched to leave two spacers between each core. The cores are stripped and the spacers are used together with the remaining hard mask features to pattern the substrate at triple the density of the original pattern.

Abstract: The present invention provides a method of improving the adhesion of a copper layer to a barrier layer on a substrate. After deposition of a barrier layer, such as TiN, an amorphous silicon layer is deposited by striking a plasma over the substrate using a silicon source gas, such as silane, and an inert gas, such as argon (Ar). A Cu layer is deposited on the amorphous silicon. In another aspect of the invention, a TiSiN layer is deposited using a silicon source gas, such as silane, and a titanium source gas, such as TDMAT, during the deposition of the TiN barrier layer.

Abstract: A method and apparatus for desorbing processing liquid from a processing liquid delivery line is provided. Non-thermal energy, such as ultrasonic energy or electromagnetic energy, is applied to a processing liquid delivery line. The non-thermal energy may be applied directly to the processing liquid delivery line, or may be applied indirectly via a conducting medium which distributes the energy along the length of the processing liquid delivery line. When non-thermal energy in the form of electromagnetic energy is employed, the frequency of the electromagnetic energy is adjusted to match the vibrational frequency of the absorbed molecules of processing liquid.

Abstract: A valve arrangement is provided that more effectively purges processing liquid from a processing liquid delivery system. With the valve arrangement only a small portion of the processing liquid path having a small wetting perimeter must be purged to affect replacement of a dysfunctional injection valve or any other component within the processing liquid delivery system. The valve arrangement comprises a first and a second isolation valve, a pump valve and purge valve configured to reduce the wetting perimeter defined by the four valves. The valve arrangement allows a dysfunctional injection valve or any other component to be replaced without health risk to humans or damage risk to a processing liquid delivery system employing the valve arrangement. During component replacement, the first and the second isolation valves are closed and the pump and the purge valves are opened so as to purge processing liquid from the isolated volume defined by the four valves.
