    摘要: In one embodiment, the invention is a guard ring for reducing particle entrapment along a moveable shaft of a substrate support. In one embodiment, the guard ring comprises a substantially annular guard ring positioned within a step formed in a sleeve that circumscribes the shaft. The guard ring is positioned to substantially seal a gap separating the shaft from the sleeve, so that the amount of particles and foreign matter that travel within or become trapped in the gap is substantially reduced. In another embodiment, a guard ring comprises a base portion having an inner perimeter and an outer perimeter, a first flange coupled to the inner perimeter, a second flange coupled to the outer perimeter, and a continuous channel separating the first flange from the second flange. The first flange is adapted to function as a spring that accommodates displacement of the shaft.

    摘要: Faults, dimensions and other characteristics of a material or structure are sensed by a coherent beam's reflection from the material during ultrasonic or very fast vibration. The reflected beam acquires a phase substantially different from its original phase and from the phase of a reference beam split from the common source beam. The reflected beam and the reference beam are superimposed by diffraction in a multiple quantum well adaptive holographic beamsplitter, and the superimposed beams are detected by a photodetector capable of detecting small interference changes from ultrasonic surface displacements or perturbations. An apparatus and method defining an improved homodyne interferometer for performing the method is described.

    摘要: A plasma etch process for etching a porous carbon-doped silicon oxide dielectric layer using a photoresist mask is carried out first in an etch reactor by performing a fluorocarbon based etch process on the workpiece to etch exposed portions of the dielectric layer while depositing protective fluorocarbon polymer on the photoresist mask. Then, in an ashing reactor, polymer and photoresist are removed by heating the workpiece to over 100 degrees C., exposing a peripheral portion of the backside of said workpiece, and providing products from a plasma of a hydrogen process gas to reduce carbon contained in polymer and photoresist on said workpiece until the polymer has been removed from a backside of said workpiece. The process gas preferably contains both hydrogen gas and water vapor, although the primary constituent is hydrogen gas. The wafer (workpiece) backside may be exposed by extending the wafer lift pins.
