  • Patent number: 7221990
    Abstract: A method, system and medium is provided for enabling improved control systems. An error, or deviation from a target result, is observed for example during manufacture of semiconductor chips. The error within standard deviation is caused by two components: a white noise component and a signal component (such as systematic errors). The white noise component is, e.g., random noise and therefore is relatively non-controllable. The systematic error component, in contrast, may be controlled by changing the control parameters. A ratio between the two components is calculated autoregressively. Based on the ratio and using the observed or measured error, the actual value of the error caused by the systematic component is calculated utilizing an autoregressive stochastic sequence. The actual value of the error is then used in determining when and how to change the control parameters.

  • Patent number: 7220673
    Abstract: In one embodiment, a method for forming a tungsten-containing material on a substrate is provided which includes forming a tungsten nucleation layer by sequentially exposing a substrate to a boron-containing gas and a tungsten-containing gas within a processing chamber during an atomic layer deposition process, and forming a tungsten bulk layer on the tungsten nucleation layer by exposing the substrate to a processing gas that contains the tungsten-containing gas and a reactive precursor gas within another processing chamber during a chemical vapor deposition process. In one example, the tungsten nucleation layer is deposited on a dielectric material, such as silicon oxide. In another example, the tungsten nucleation layer is deposited on a barrier material, such as titanium or titanium nitride. Other examples provide that the tungsten nucleation layer and the tungsten bulk layer are deposited in the same processing chamber.

  • Patent number: 7218983
    Abstract: In at least one aspect, the invention provides an electronic device fabrication facility (Fab) that uses small lot carriers that may be transparently integrated into an existing Fab that uses large lot carriers. A manufacturing execution system (MES) may interact with the inventive small lot Fab as if the small lot Fab is any other Fab component in an existing large lot Fab without requiring knowledge of how to control small lot Fab components (e.g., beyond specifying a processing recipe). A small lot Fab according to the present invention may encapsulate the small lot Fab's internal use of small lot components and present itself to a large lot Fab's MES as if the small lot Fab is a component that uses large lot carriers.

  • Publication number: 20070105355
    Abstract: An implanter provides two-dimensional scanning of a substrate relative to an implant beam so that the beam draws a raster of scan lines on the substrate. The beam current is measured at turnaround points off the substrate and the current value is used to control the subsequent fast scan speed so as to compensate for the effect of any variation in beam current on dose uniformity in the slow scan direction. The scanning may produce a raster of non-intersecting uniformly spaced parallel scan lines and the spacing between the lines is selected to ensure appropriate dose uniformity.

  • Patent number: 7214628
    Abstract: A method of fabricating a gate of a transistor device on a semiconductor substrate, includes the steps of placing the substrate in a vacuum chamber of a plasma reactor and introducing into the chamber a process gas that includes oxygen while maintaining a vacuum pressure in the chamber. An oxide insulating layer on the order of several Angstroms in thickness is formed at the surface of the substrate by generating a plasma in a plasma generation region within the vacuum chamber during successive “on” times, and allowing ion energy of the plasma to decay during successive “off” intervals separating the successive “on” intervals, the “on” and “off” intervals defining a controllable duty cycle. During formation of the oxide insulating layer, the duty cycle is limited so as to limit formation of ion bombardment-induced defects in the insulating layer, while the vacuum pressure is limited so as to limit formation of contamination-induced defects in the insulating layer.

  • Patent number: 7214619
    Abstract: A barrier layer is formed in an integrated circuit by providing a metal target near a ceiling of the chamber and a wafer support pedestal facing the target near a floor of the chamber. A process gas is introduced into the vacuum chamber. A target-sputtering plasma is maintained at the target to produce a stream of principally neutral atoms flowing from the target toward the wafer for vapor deposition. A wafer-sputtering plasma is maintained near the wafer support pedestal to produce a stream of sputtering ions toward the wafer support pedestal for re-sputtering. The sputtering ions are accelerated across a plasma sheath at the wafer in a direction normal to a surface of the wafer to render the sputter etching highly selective for horizontal surfaces.

  • Publication number: 20070095654
    Abstract: A multi-step sputtering process in plasma sputter reactor having target and magnetron operable in two modes, for example, in a substrate sputter etch and a substrate sputter deposition. The target has an annular vault facing the wafer to be sputter coated. Various types of magnetic means positioned around the vault create a magnetic field supporting a plasma extending over a large volume of the vault. An integrated copper via filling process with the inventive reactor or other reactor includes a first step of highly ionized sputter deposition of copper, which can optionally be used to remove the barrier layer at the bottom of the via, a second step of more neutral, lower-energy sputter deposition of copper to complete the seed layer, and a third step of electroplating copper into the hole to complete the metallization. The first two steps can be also used with barrier metals.
