Abstract: A method for a haptic feedback system for one or more elevator systems includes detecting a user indication provided via a user interface device of one of the one or more elevator systems, receiving at least one status information, and generating a haptic output signal via the user interface device in accordance with the at least one status information. A control unit, a haptic feedback system and a computer program performing at least part of the method is disclosed.

Abstract: Embodiments of the invention generally provide an apparatus and method for replenishing organic molecules in an electroplating bath. The replenishment process of the present invention may occur on a real-time basis, and therefore, the concentration of organics minimally varies from desired concentration levels. The replenishment method generally includes conducting pre-processing depletion measurements in order to determine organic depletion rates per current density applied in the electroplating system. Once the organic depletion rates per current density are determined, these depletion rates may be applied to an electroplating processing recipe to calculate the volume of organic depletion per recipe step. The calculated volume of organic depletion per recipe step may then be used to determine the volume of organic molecule replenishment per unit of time that is required per recipe step in order to maintain a desired concentration of organics in the plating solution.

Abstract: An apparatus and a method of depositing a catalytic layer comprising at least one metal selected from the group consisting of noble metals, semi-noble metals, alloys thereof, and combinations thereof in sub-micron features formed on a substrate. Examples of noble metals include palladium and platinum. Examples of semi-noble metals include cobalt, nickel, and tungsten. The catalytic layer may be deposited by electroless deposition, electroplating, or chemical vapor deposition. In one embodiment, the catalytic layer may be deposited in the feature to act as a barrier layer to a subsequently deposited conductive material. In another embodiment, the catalytic layer may be deposited over a barrier layer. In yet another embodiment, the catalytic layer may be deposited over a seed layer deposited over the barrier layer to act as a “patch” of any discontinuities in the seed layer. Once the catalytic layer has been deposited, a conductive material, such as copper, may be deposited over the catalytic layer.

Abstract: Methods, compositions, and apparatus are provided for planarizing conductive materials disposed on a substrate surface by an chemical polishing technique. In one aspect, a substrate having conductive material disposed thereon is disposed on a substrate support and exposed to a composition containing an oxidizing agent and an inorganic etchant. The substrate is planarized by the composition without the presence of mechanical abrasion. The substrate may optionally be rotated, agitated, or both during exposure to the composition. The method removes conductive materials forming protuberances on the substrate surface at a higher rate than conductive materials forming recesses on the substrate surface.

Abstract: An electrolyte cell receives a substrate for processing, a first electrode disposed in the electrolyte cell, the first electrode comprising at least a contact ring, a second electrode disposed within the electrolyte cell and spaced from the first electrode, and a porous membrane that is connected to the electrolyte cell and extends across at least a portion of the electrolyte cell, the membrane is positioned between a location for positioning a substrate when processing and surrounding electrolyte.
