  • Publication number: 20040003894
    Abstract: A method and apparatus is provided for depositing and planarizing a material layer on a substrate. In one embodiment, an apparatus is provided which includes a partial enclosure, a permeable disc, a diffuser plate and optionally an anode. A substrate carrier is positionable above the partial enclosure and is adapted to move a substrate into and out of contact or close proximity with the permeable disc. The partial enclosure and the substrate carrier are rotatable to provide relative motion between a substrate and the permeable disc. In another aspect, a method is provided in which a substrate is positioned in a partial enclosure having an electrolyte therein at a first distance from a permeable disc. A current is optionally applied to the surface of the substrate and a first thickness is deposited on the substrate. Next, the substrate is positioned closer to the permeable disc and a second thickness is deposited on the substrate.

  • Patent number: 6640151
    Abstract: A system/method for interactively monitoring and adjusting product output from a module that includes two or more preparation tools. The output is a result of the coordinated effort of the two or more semiconductor preparation tools making up the module. The first of the tools is capable of implementing a first process on a semiconductor product and producing a first output. The second of the tools is configured to receive as input the first output from the first tool. The second tool is also capable of implementing a second process on the semiconductor product and producing a second output. A module control mechanism is capable of facilitating the exchange of information between the first tool and the second tool so that the module yields a desired semiconductor product output. Certain information can also be exchanged between the first and second tools. Other system/method embodiments for output/production control are also envisioned.

  • Patent number: 6427703
    Abstract: A cleaning system for use with a micro-column array, electron beam lithography system is described. The cleaning system includes an oxidizer source and an oxidizer distribution mechanism that introduces an oxidizer into the imaging chamber of the lithography system. The oxidizer is pumped into the chamber at a flow rate and pressure that maintains a required sub-atmospheric pressure within the imaging chamber. The oxidizer acts to oxidize carbon contamination that may be present in the imaging chamber or on the surfaces of components within the chamber, such as the imaging mask. A volatile oxidized carbon gas is produced by the oxidization of the carbon contaminants. The oxidized carbon gas is pumped out of the imaging chamber to thereby remove the carbon contamination from the chamber.

  • Patent number: 6381021
    Abstract: The present invention provides a method and apparatus for measuring the reflectivity of a substrate surface in situ. A transmitting assembly includes a light source positioned externally to a vacuum chamber and proximate an opening to transmit an optical beam into the vacuum chamber. An optical beam supplied by the light source is transmitted into the chamber via one or more optical devices such as fiber optics cables, lens and the like. Reflected portions of the optical beam are collected by a receiving assembly. A signal processing system coupled to the receiving assembly is programmed to determine the reflectivity of a substrate disposed in the vacuum chamber.

  • Patent number: 6352467
    Abstract: A fabrication tool integrates one or more electrodeposition stations with a CMP apparatus. The tool may transport substrates from the electroplating stations to the CMP apparatus without an intervening cleaning step. In addition, the thickness of an electrodeposited layer may be measured at a metrology station prior to polishing utilizing an instrument which physically contacts the surface of the substrate, and the measured thickness may be used to adjust the polishing parameters. Furthermore, the fabrication tool may have a single interface in which a dry and clean wafer is returned to the interface.
