Latest Patents
One of her latest patents is titled "Silicon pen nanolithography." This patent discloses methods of lithography using a tip array with multiple pens attached to a backing layer. The tips can comprise a metal, metalloid, and/or semi-conducting material, while the backing layer can consist of an elastomeric polymer. The tip array is utilized to perform a lithography process where the tips are coated with an ink, such as a patterning composition, which is deposited onto a substrate upon contact. The tips can be easily leveled onto a substrate, and this leveling can be monitored optically by observing changes in light reflection of the backing layer or near the tips upon contact with the substrate surface.
Another notable patent is "Generation of combinatorial patterns by deliberate tilting of a polymer-pen array." This disclosure relates to a method of forming patterns with elements of varying sizes on a substrate surface using a tilted pen array. The process involves selecting a tilt geometry for the pen array concerning the substrate, inducing this tilt, and forming a pattern on the substrate surface. The size of the formed pattern elements varies across the substrate surface along the tilted axis or axes, allowing for intricate designs.
