摘要:
The present invention pertains to an apparatus and method useful in semiconductor processing. The apparatus and method can be used to provide a seal which enables a first portion of a semiconductor processing chamber to be operated at a first pressure while a second portion of the semiconductor processing chamber is operated at a second, different pressure. The sealing apparatus and method enable processing of a semiconductor substrate under a partial vacuum which renders conductive/convective heat transfer impractical, while at least a portion of the substrate support platform is under a pressure adequate to permit heat transfer using a conductive/convective heat transfer means. The sealing apparatus comprises a thin, metal-comprising layer, typically in the form of a strip or band, brazed to at least two different surfaces within said processing chamber, whereby the first and second portions of the semiconductor processing chamber are pressure isolated from each other. Preferably, the metal-comprising layer exhibits a cross-sectional thickness of less than about 0.039 in. (1 mm). The invention is particularly useful when there is a differential in linear expansion coefficient of at least 3.times.10.sup.-3 in./in./.degree.C., measured at 600.degree. C., between the surfaces to be bridged by the thin, metal-comprising layer.

A readily removable deposition shield assembly for processing chambers such as chemical vapor deposition (CVD), ion implantation, or physical vapor deposition (PVD) or sputtering chambers, is disclosed. The shield assembly includes a shield member which is mounted to the chamber for easy removal, such as by screws, and defines a space along the periphery of the substrate support. A shield ring is inserted into the peripheral space and is thus mounted in removable fashion and is automatically centered about the substrate. The shield ring overlaps the cylindrical shield and a deposition ring. The deposition ring removably rests upon a flange extending from the outer periphery of a substrate support pedestal. Collectively, these components prevent deposition on the chamber and hardware outside the processing region.
摘要:
Apparatus for promoting heat transfer between a first volume (chamber volume) and a second volume (expandable, substrate support platform volume). Specifically, the apparatus comprises: a chamber defining a chamber volume that contains a chamber atmosphere, e.g., a partial vacuum; a substrate support platform that defines an expandable volume that contains a heat transfer medium, e.g., air; and a seal that isolates the chamber volume from the heat transfer medium. The substrate support platform further comprises: a substrate support platen that has a first surface located within the chamber volume and a second surface located within the expandable volume; a housing sealed to the second surface of the substrate support platen; and a expandable member such as a bellows, attached to the housing, to provide for expansion of the expandable volume that is defined by the housing and the bellows. The housing is typically fabricated of metal and the substrate support is typically fabricated of ceramic. The seal forms a hermetic junction between the ceramic substrate support and the metal housing.

The present invention generally comprises equipment for an automated high volume batch work-piece manufacturing factory comprising work-piece handling and work-piece processing in a high productivity factory architecture capable of producing 1,000 or more work-piece an hour. The work-pieces may be presented to the equipment from a stacked supply to a parallel array. Additionally, the work-pieces may be transferred between manufacturing architectures by an array to array batch transfer. The work-pieces may be transferred within the manufacturing architecture in a parallel to parallel batch transfer operation. The robotic operations may be between robotic devices, between robotic devices and processing equipment, and within processing equipment.

A scrubber box is provided that includes a tank adapted to receive a substrate for cleaning, supports outside of the tank and adapted to couple to ends of scrubber brushes disposed within the tank, a motor mounted to each of the supports and adapted to rotate the scrubber brushes, a base to which the supports are pivotally mounted via spherical bearings adapted to permit toe-in of the scrubber brushes, a brush gap actuator adapted, via a crank and rocker mechanism, to substantially simultaneously pivot the supports toward or away from each other so as to permit the scrubber brushes to substantially simultaneously achieve or break contact with the substrate, and a toe-in actuator adapted to move two of the spherical bearings toward or away from each other so as to adjust a toe-in angle between the scrubber brushes.
摘要:
A sputtering target, particularly for sputter depositing a target material onto large rectangular panels, in which a plurality of target tiles are bonded to a backing plate in a two-dimensional non-rectangular array such that the tiles meet at interstices of no more than three tile, thus locking the tiles against excessive misalignment during bonding. The rectangular tiles may be arranged in staggered rows or in a herringbone or zig-zag pattern. Hexagonal and triangular tiles also provide many of the advantages of the invention.
