摘要:
A method and apparatus for an electrochemical processing cell that is configured to minimize bevel and backside deposition. The apparatus includes a contact ring assembly for supporting a substrate, a thrust plate movably positioned to engage a substrate positioned on the contact pins, and a lip seal member positioned to contact the thrust plate and the contact ring to prevent fluid flow therebetween. The lip seal includes a at least one bubble release channel formed therethrough. The method includes positioning an electric field barrier between a backside substrate engaging member and a frontside substrate supporting member to prevent electric field from traveling to the bevel and backside of the substrate. The electric field barrier including at least one bubble release channel formed therethrough.

A method for cleaning the electrical contact areas or substrate contact areas of an electrochemical plating contact ring is provided. Embodiments of the method include positioning a substrate on a substrate support member having one or more electrical contacts, chemically plating a metal layer on at least a portion of a surface of the substrate, removing the processed substrate from the support member, and cleaning the one or more electrical contacts with a vapor mixture comprising an alcohol. In another aspect, the method includes spraying the vapor mixture on the electrical contacts while rotating the substrate support member.

摘要:
A plasma applicator having a tube that is surrounded by a cooling jacket such that a volume is defined proximate the tube. The volume is filled with a thermal transfer medium to couple heat from the tube to the cooling jacket. The cooling jacket contains an aperture through which energy is transmitted to a process gas contained in the tube. As such, the process gas is infused with energy and a plasma is formed in the tube.

A system for measuring substrate concentricity includes a substrate support member adapted to rotate a substrate around a substantially vertical axis. The substrate includes a mounting surface and a process surface. The system also includes a spin cup positioned below the substrate and a translatable arm mounted a predetermined distance above the process surface of the substrate. The translatable arm is adapted to translate along a radius of the substrate. The system further includes an optical emitter mounted on the translatable arm and an optical detector mounted on the translatable arm.

An apparatus and method for measuring a height of an object above a surface includes a housing with a first portion having an upper surface and a lower surface and an extension portion extending a first distance from the lower surface of the first portion. The extension portion defines a cavity opposing the lower surface of the first portion. The apparatus further includes one or more actuators passing through the lower surface of the first portion of the housing and extending into the cavity. Additionally, the apparatus includes a plate supported by one or more flexible members coupled to the extension portion. The plate has a top surface and a bottom surface that lies in a plane substantially parallel to the surface. Moreover, the apparatus includes a plurality of sensors disposed at predetermined positions of the plate. Each of the plurality of sensors is responsive to a height measured between each of the plurality of sensors and the surface.
