  • Patent number: 6632282
    Abstract: A planetary multi-substrate holder system for material deposition includes a substrate holder having circumferentially shaped openings in which disk-like substrates of a smaller diameter than the diameter of the openings are maintained. Upon rotation of the substrate holder, either in a vertical plane, or in a horizontal plane, the substrates self-rotate within each opening due to either gravity force (for vertically rotated substrate holder), or due to centrifugal force (for horizontally rotated substrate holder) applied to the substrates. The planetary multi-substrate system obviates the need for mechanical individual gears to rotate substrates for material deposition, and, as a sequence, yields an extended service life of the system, as well as agreeability with high temperatures used in material deposition process, and reduced cost of a final product.

    Abstract: A wafer chuck includes alignment members that allows a semiconductor wafer to be properly aligned on the chuck without using a separate alignment stage. The alignment members may be cams, for example, attached to arms of the wafer chuck. These members may assume an alignment position when a robot arm places the wafer on the chuck. In this position, they guide the wafer into a proper alignment position with respect to the chuck. During rotation at a particular rotational speed, the alignment members move away from the wafer to allow liquid etchant to flow over the entire edge region of the wafer. At still higher rotational speeds, the wafer is clamped into position to prevent it from flying off the chuck. A clamping cam or other device (such as the alignment member itself) may provide the clamping.

  • Patent number: 6503379
    Abstract: An exemplary mobile plating system and method are provided for performing a plating process using virtually any known or available deposition technology for coating or plating. The mobile plating system may include a vacuum chamber positioned in a mobile storage volume, an external vacuum pump, and a control module to control the operation of some or all of the operations of the external vacuum pump. The external vacuum pump is positioned in the mobile storage volume when the mobile plating system is in transit, and is positioned external to the mobile storage volume when the mobile plating system is stationary and in operation. The external vacuum pump may be mounted on a skid, and, in operation, the external vacuum pump couples with the vacuum chamber to assist with producing a desired pressure in the vacuum chamber.

  • Patent number: 6495010
    Abstract: A differentially pumped deposition system is described that includes a deposition source, such as a magnetron sputtering source, that is positioned in a first chamber. The deposition source generates deposition flux comprising neutral atoms and molecules. A shield that defines an aperture is positioned in the path of the deposition flux. The shield passes the deposition flux though the aperture and substantially blocks the deposition flux from propagating past the shield everywhere else. A substrate support is positioned in the second chamber adjacent to the shield. The pressure in the second chamber is lower than a pressure in the first chamber. A dual-scanning system scans the substrate support relative to the aperture with a first and a second motion, thereby improving uniformity of the deposited thin fill.

  • Patent number: 6494956
    Abstract: An apparatus for processing a workpiece in a micro-environment includes a workpiece housing connected to a motor for rotation. The workpiece housing forms a substantially closed processing chamber where processing fluids are distributed across at least one face of the workpiece by centrifugal force generated during rotation of the housing. The housing may also be detached from the motor and moved to another location. The housing consequently serves as a processing chamber, as well as a storage or transport chamber.

  • Publication number: 20020185230
    Abstract: An article (e.g. a semiconductor wafer) is held in an article holder by means of a number of gas flows emitted from gas vortex chambers. Some of the gas flows act to cool an adjacent article portion more than the other gas flows. For example, some of the vortex chambers emit more gas per unit of time than the other chambers. More cooling is provided to those portions of the article which are heated more during processing. Greater temperature uniformity can be achieved.

  • Patent number: 6485565
    Abstract: Thin films of single crystal-like materials are made by using flow-through ion beam deposition during specific substrate rotation around an axis in a clocking action. The substrate is quickly rotated to a selected deposition position, paused in the deposition position for ionized material to be deposited, then quickly rotated to the next selected deposition position. The clocking motion can be achieved by use of a lobed cam on the spindle with which the substrate is rotated or by stopping and starting a stepper motor at long and short intervals. Other symmetries can be programmed into the process, allowing virtually any oriented inorganic crystal to be grown on the substrate surface.

  • Patent number: 6485616
    Abstract: A system and method for coating substrates. The coating process includes an improved capacity and uniformity through the addition of a second motion component in which the substrates move in a closed path. A major portion of the path is linear and the configuration of the coating machine is such that all substrates follow the same trajectory with respect to the machine during the coating process, resulting in a coating which is substantially the same for all substrates.
