Latest Patents

Nillesen holds a patent for a method of repairing a defect in a lithographic mask comprising metal. This invention provides a straightforward method for restoring a transparent defect in a lithographic mask. The process involves applying a photosensitive layer to the mask and introducing it into a solution of metal ions. The mask is then exposed at the defect area, allowing the photosensitive layer to deposit the metal ions as metal under radiation. The exposure continues until the metal deposition prevents further radiation from penetrating the photosensitive layer, effectively stopping overgrowth of the metal deposit.
