摘要:
A method for controlling the operation of a magnetron source for sputtering a surface of a target in a vacuum chamber, the method including the steps of: during a low pressure phase of sputtering, causing a magnetic field generated by a the magnetron source to be confined primarily to an inner region of the surface of the target so as to reduce leakage of electrons away from the target during sputtering; and during a subseguent high pressure phase of sputtering, causing the magnetic field generated by the magnet assembly to extend into the outer region of the surface of the target so as to sputter material from the outer region of the surface of the target. The pressure of the high pressure phase of sputtering is higher than the pressure of the low pressure phase of sputtering.

摘要:
An exclusion ring system for depositing a film with multiple exclusion zones on a substrate in a deposition apparatus having a pedestal for supporting the substrate at different positions. A first exclusion ring is positioned above the substrate and pedestal and extends over a first zone overlying the perimeter of the substrate up to a first inner periphery. A second ring is positioned between the first ring and the substrate and extends over a second zone overlying the perimeter of the substrate outwardly of the first zone to a second inner periphery lying outwardly of the first inner periphery. When the pedestal is in a raised position, it supports the rings. When the pedestal is in a lowered position, the rings are supported by legs resting on a stationary wall, the legs of the first ring being effectively longer than the legs of the second ring so that the rings are sequentially moved away from the substrate as the pedestal is lowered. Initially, the first ring is in a position proximate the substrate to prevent deposition of the first film over the first zone. Then the pedestal is lowered to a position where the first ring is moved away from the substrate by its leg being supported. This leaves the second ring as an effective exclusion ring at the second position so that the second film is deposited over the first and over the second zone and also extends outwardly to cover and protect the edge of the first film.

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.

Embodiments of the present invention generally relate to a small volume chamber with a substrate support. One embodiment of a processing chamber includes a first assembly having a substrate support, a pumping ring disposed around a perimeter of the substrate receiving surface, and a gas distribution assembly disposed over the substrate support. The chamber may further include a gas distribution assembly disposed over the substrate support. The first assembly and the gas distribution assembly can be selectively positioned between an open position and a closed position.

A robot blade and a method of using the robot blade for transferring objects, namely substrates, through a process system, the robot blade comprising an upper platform having a first object supporting surface and a lower platform having a second object supporting surface. The robot blade is mounted onto a moveable member, and the assembly facilitates substrate transfers, such as removal of a processed substrate and insertion of an unprocessed substrate within a processing chamber through a single entry of the robot blade into the processing chamber.

An improved plasma applicator for remotely generating a plasma for use in semiconductor manufacturing is provided. In one embodiment, a plasma applicator is comprised of a chamber assembly, a removable waveguide adapter and a circular clamp which secures the adapter to the chamber assembly. The chamber assembly includes an aperture plate, a microwave transparent window, a chamber body and a microwave sensor which is mounted on the chamber body. The chamber body has a proximate end opening adapted to admit microwave energy into the cavity and a distal end disposed generally on the opposite side of the cavity from the proximate end opening. The chamber body further has a gas outlet port adapted to permit the flow of an excited gas out of the cavity and a gas inlet port adapted to admit a precursor gas into the cavity. The gas inlet port has a center axis which is disposed between the proximate end opening of the chamber body and the midpoint between the proximate end opening and the distal end of the body.
