The chuck can include a passage extending along a periphery of the chuck and dividing the chuck into an inner portion and an outer sidewall portion, and a first multiple of openings through the outer sidewall portion of the chuck and interconnected with the passage. The passage can be configured to transport a fluid. The first multiple of openings can be configured to dispense the fluid.

An apparatus for inserting a seal member into a seal groove includes a tray. The tray includes a holding groove formed in a front surface for containing the seal member. The holding groove is sized and shaped to correspond with the seal groove. A method of installing a seal member into a seal groove includes aligning the holding groove with the seal groove, and applying a pressure to a back surface of the tray, thereby deforming the tray and inserting the seal member into the seal groove.

A semiconductor manufacturing apparatus includes a process container. A holder is disposed in the process container, and is arranged to hold a substrate including a first surface and a second surface on an opposite side to the first surface. The holder includes a mask portion that covers a first area of the first surface and exposes a second area different from the first area. The mask portion includes a first layer in contact with the first surface of the substrate and a second layer spaced further from the substrate than the first layer. The first layer is recessed further than the second layer in a direction toward the first area in an edge portion of the mask portion that partitions the first area and the second area.

A substrate process station includes a housing including a transport region and process region. The process station further includes a magnetic levitation assembly disposed in the transport region configured to levitate and propel a substrate carrier. The magnetic levitation assembly includes a first track segment including first rails disposed in the transport region and below the process region, wherein the first rails each include a first plurality of magnets. The process station further includes a pedestal assembly comprising a pedestal disposed within the housing. The pedestal is moveable between a pedestal transfer position and a process position, wherein the pedestal is disposed between the first rails in the pedestal transfer position to receive a substrate from the substrate carrier, and wherein the pedestal is moveable between the first rails to position the received substrate in the process region in the process position.

A semiconductor substrate carrying container, such as a front opening unified pod or shipping box, that includes a container shell having a plurality of walls, a front, and a rear, the plurality of walls defining an interior space that is sized to be able to receive a plurality of semiconductor substrates or trays, and a support structure configured to receive the plurality of semiconductor substrates or trays. The support structure includes at least one support wall that is formed by a plurality of corrugation portions provided along opposite sides of a centerline along a vertical plane at a center of the at least one support wall.

A wide-coverage edge ring configured to be arranged above a bottom ring in a substrate processing chamber includes an upper surface, a lower surface that includes a lower surface step that extends downward from the lower surface and is configured to be received within and interface with a pocket defined at least partially by an upper surface of the bottom ring and an inner surface of a chamber liner, an inner diameter, a ledge defined in the inner diameter of the edge ring, and an outer diameter. The outer diameter of the edge ring includes a projection that extends radially outward from the edge ring and defines an inward step in the outer diameter, the projection and the inward step are configured to interface with an upper end of the chamber liner, and the projection is configured to extend at least partially over the upper end of the chamber liner.

A radiation shield and an assembly and a reactor including the radiation shield are disclosed. The radiation shield can be used to control heat flux from a susceptor heater assembly and thereby enable better control of temperatures across a surface of a substrate placed on a surface of the susceptor heater assembly.

There is provided a substrate processing apparatus comprising: a substrate transfer chamber having a floor provided with a first magnet; a substrate transfer module including a stage on which a substrate is placed, a traveling plate disposed below the stage, and a second magnet having a repulsive force with respect to the first magnet, the substrate transfer module being configured to be movable in the substrate transfer chamber by magnetic levitation using the repulsive force; and a substrate processing chamber disposed on an upper surface side of the substrate transfer chamber to process the substrate, the substrate processing chamber having an opening having a size that allows at least a part of the stage on which the substrate is placed to pass therethrough, the opening being open toward the inside of the substrate transfer chamber. The substrate is processed in a state where the stage on which the substrate is placed is inserted into the substrate processing chamber through the opening by raising the substrate transfer module and the opening is closed by the traveling plate.
