  • Method and apparatus for moving a material removal tool with low tool accelerations
    Patent number: 5375064
    Abstract: A stage 14 supporting a material removal tool 12 is instructed by a controller 16 through interface 18 to accelerate and decelerate the material removal tool 12 within at least one predetermined spatial interval while satisfying the dwell-time required to remove a predetermined amount of material to achieve a desired thickness of the spatial interval.

  • Highly durable noncontaminating surround materials for plasma etching
    Patent number: 5364496
    Abstract: A support and positioning apparatus (10) for supporting and positioning a wafer (12), substrate or the like in a plasma assisted chemical etching process. Surround components (14, 16, 18, 20) positioned around the substrate (12) are comprised of substantially pure magnesium or are aluminum coated with a magnesium fluoride coating such that as a plasma tool associated with the plasma etching process traverses the edge of the substrate (12), the plasma etching environment generated from a fluorine containing feed gas emitted from the plasma tool does not significantly erode the surround components (14, 16, 18, 20) or cause contamination of the substrate (12).
