Abstract: A batch processing oven comprising a processing chamber and a rack configured to be positioned in the processing chamber. The rack is configured to support a plurality of substrates and a plurality of panels in a stacked manner such that one or more substrates of the plurality of substrates are positioned between at least one pair of adjacent panels of the plurality panels. Vertical gaps separate each substrate of the one or more substrates from an adjacent substrate or panel on either side of the substrate.

Abstract: A solder reflow oven includes a processing chamber that defines an enclosure. The enclosure includes a spindle configured to support a substrate and rotate the substrate about a central axis of the processing chamber. The spindle is also configured to move vertically along the central axis and position the substrate at different locations within the enclosure. The oven further includes a chemical delivery tube configured to direct a chemical vapor into the enclosure, a lamp assembly configured to heat a top surface of the substrate, and a lift assembly configured to move the spindle along the central axis.

Abstract: The present disclosure provides a fuel cell stack having a plurality of bipolar plates aligned in a stack between a pair of bipolar plates wherein each of the bipolar plates includes an outer bead having an interior cavity; and an inner bead having a trough wherein the inner bead extends into the interior cavity of the outer bead. The trough of the inner bead may be at least about 50% filled with an elastomeric seal.

Abstract: A loadlock chamber for a semiconductor processing apparatus comprises an index platform or registration plate, a shaft extending through a wall of the chamber to actuate the platform, and a bellows located on the outside of the chamber to isolate the shaft from the external environment. A seal is placed between the bottom of the registration plate and the wall of the chamber so as to isolate the space under the registration plate and within the bellows from the remainder of the chamber when the platform is in a fully lowered position. A gutter is formed in a wall of the chamber below the registration plate to catch particulate matter, such as broken wafer particles. A method of accessing the interior of a loadlock chamber limits exposure of the space within the bellows to the external environment.

Abstract: A reactor chamber is positioned between a top array of heat lamps and a bottom array of heat lamps. At least one of the heat lamps forming the top and bottom arrays features a segmented filament such that power output along the length of the heat lamp differs. In one configuration, the heat lamp has a pair of high energy output regions spaced from each other by a lower energy output region. In some configurations, at least one of the heat lamps forming the top and bottom arrays is non-linear, such as U-shaped. In further configurations, a non-linear heat lamp has a segmented filament with segments or areas of different winding density.

Abstract: A device that supports a substrate in a non-containing manner so as to controllably move the substrate within a substrate processing system. The device includes an end effector carrying support pads each having a vertical gas outlet and a horizontal outlet communicating with a gas supply to form a plurality of vertical gas jets and a plurality of horizontal gas jets. The vertical gas jets impinge on a lower surface of the substrate to urge the substrate into a fixed vertical position with respect to the support pads and the horizontal gas jets impinge on the substrate edge to urge the substrate into a fixed horizontal position with respect to the pads.

Abstract: A Bernoulli wand type semiconductor wafer pickup device that is adapted to regulate the temperature of a wafer while the wafer is being repositioned within a semiconductor processing system. In one embodiment, the device is comprised of a resistive heating element that is adapted to raise the temperature of the pickup device. In particular, by raising the temperature of the pickup device, a portion of the thermal radiation emitted from the device is absorbed by the wafer, thus providing a means for regulating the wafer temperature. In another embodiment, the device is adapted with the characteristics of a black body absorber so as to enable the device to optimally absorb thermal radiation from external radiant sources, thereby providing a means for increasing the temperature of the device. In another embodiment, the device is coated with reflective material that enables a large portion of thermal radiation emitted from the wafer to be reflected and absorbed back into the wafer.

Abstract: A stackable cassette for testing at least one separate wafer during the processing of a plurality of semiconductor wafers is disclosed. The stackable cassette includes a bottom surface which conforms to a top portion of a base cassette having a plurality of wafers. In addition, the stackable cassette includes two or more supports which extend vertically from the bottom surface and a top surface horizontally connected to the two supports. The supports include ribs which form channels for holding at least one wafer. When processing the plurality of wafers, the stackable cassette is placed on top of a base cassette. A specified processed wafer is placed within the stackable cassette. The stackable cassette is then removed for inspection of the test wafer.

Abstract: Two FOUPs are stacked and moved together towards an equipment wall by a horizontal actuator. FOUP doors are withdrawn as a unit by a horizontal actuator, and lowered as a unit by a vertical actuator to provide access to the interior of the FOUPs.
