  • Publication number: 20150076371
    Abstract: The present disclosure relates to a lithographic tool arrangement for semiconductor workpiece processing. The lithographic tool arrangement groups lithographic tools into clusters, and selectively transfers a semiconductor workpiece between a plurality of lithographic tools of a first type in a first cluster to a plurality of lithographic tools of a second type in a second cluster. The selective transfer is achieved though a transfer assembly, which is coupled to a defect scan tool that identifies defects generated in the lithographic tool of the first type. The disclosed lithographic tool arrangement also utilizes shared structural elements such as a housing assembly, and shared functional elements such as gases and chemicals. The lithographic tool arrangement may consist of baking, coating, exposure, and development units configured to provide a modularization of these various components in order to optimize throughput and efficiency for a given lithographic fabrication process.

  • Patent number: 8955530
    Abstract: A wafer chuck is cleaned using a cleaning cap to remove processing residue and particulate matter. The cleaning cap is configured to overlie and align with the wafer chuck and includes a base and a first roller connected to the base and having wound therearound a cleaning cloth. The cleaning cap further includes a second roller connected to the base and having attached thereto a free end of the cleaning cloth. During use, the cleaning cloth winds upon the second roller from the first roller when the second roller rotates about its axis. The cleaning cap can be positioned relative the wafer chuck by way of a manipulator to ensure the cleaning cloth contacts the wafer chuck with sufficient force. The cleaning cloth rubs the wafer chuck with both translational motion and rotational motion.

  • Patent number: 8906599
    Abstract: A method and system to improve scanner throughput is provided. An image from a reticle is projected onto a substrate using a continuous linear scanning procedure in which an entire column of die or cells of die is scanned continuously, i.e. without stepping to a different location. Each scan includes translating a substrate with respect to a fixed beam. While the substrate is translated, the reticle is also translated. When a first die or cell of die is projected onto the substrate, the reticle translates along a direction opposite the scan direction and as the scan continues along the same direction, the reticle then translates in the opposite direction of the substrate thereby forming an inverted pattern on the next die or cell. The time associated with exposing the substrate is minimized as the stepping operation only occurs after a complete column of cells is scanned.

  • Patent number: 8860941
    Abstract: One embodiment relates to a method for semiconductor workpiece processing. In this method, a baseline tool induced shift (TIS) is measured by performing a baseline number of TIS measurements on a first semiconductor workpiece. After the baseline TIS has been determined, the method determines a subsequent TIS based on a subsequent number of TIS measurements taken on a first subsequent semiconductor workpiece. The subsequent number of TIS measurements is less than the baseline number of TIS measurements.

  • Patent number: 8848163
    Abstract: A lithography apparatus generates a tunable magnetic field to facilitate processing of photoresist. The lithography apparatus includes a chamber and a substrate stage in the chamber operable to hold a substrate. A magnetic module provides a magnetic field to the substrate on the substrate stage. The magnetic module is configured to provide the magnetic field in a tunable and alternating configuration with respect to its magnitude and frequency. The magnetic field is provided to have a gradient in magnitude along a Z-axis that is perpendicular to the substrate stage to cause magnetically-charged particles disposed over the substrate stage to move up and down along the Z-axis. The lithography apparatus also includes a radiation energy source and an objective lens configured to receive radiation energy from the radiation energy source and direct the radiation energy toward the substrate positioned on the substrate stage.

  • Patent number: 8544317
    Abstract: A method and apparatus provide for simultaneously moving multiple semiconductor wafers in opposite directions while simultaneously performing processing operations on each of the wafers. The semiconductor wafers are orientated in coplanar fashion and are disposed on stages that simultaneously translate in opposite directions to produce a net system momentum of zero. The die of the respective semiconductor wafers are processed in the same spatial sequence with respect to a global alignment feature of the semiconductor wafer. A balance mass is not needed to counteract the motion of a stage because the opposite motions of the respective stages cancel each other.

  • Patent number: 8338262
    Abstract: A dual wavelength exposure system provides for patterning a resist layer formed on a wafer for forming semiconductor devices, using two exposure operations, one including a first radiation having a first wavelength and the other including a second radiation including a second wavelength. Different or the same lithography tool may be used to generate the first and second radiation. For each die formed on the semiconductor device, a critical portion of the pattern is exposed using a first exposure operation that uses a first radiation with a first wavelength and a non-critical portion of the pattern is exposed using a second exposure operation utilizing the second radiation at a second wavelength. The resist material is chosen to be sensitive to both the first radiation having a first wavelength and the second radiation having the second wavelength.
