  • Metal plating of grids for ion beam sputtering
    Patent number: 11581164
    Abstract: Provided herein are deposition systems utilizing coated grids in an ion deposition process which provide more predictable erosion of the coating rather than erosion of the grid itself. Further, coatings may be utilized in which the coating material does not act as a contaminant to the deposition process, thereby eliminating contamination of the sample surface due to deposition of unwanted grid material. Also provided are methods of refurbishing a coated grid by periodically replacing the coating material thus protecting the grid itself and allowing a grid to be used indefinitely.
    Type: Grant
