Latest Patents

One of her latest patents is titled "Method for selective etching of a block copolymer." This innovative method involves a two-step etching process using plasma to selectively etch different polymer phases within a block copolymer. The first step utilizes a plasma formed from carbon monoxide or a fluorocarbon gas mixture to partially etch the first polymer phase while depositing a carbon layer on the second polymer phase. The second step employs a different gas mixture to fully etch the first polymer phase and the carbon layer on the second polymer phase.

Another notable patent is "Method for making patterns by self-assembly of block copolymers." This method outlines a process for creating patterns on a substrate surface using a block copolymer layer. It involves forming a mask, depositing the block copolymer, reorganizing it, and then eliminating one of the phases to create holes that are widened into a continuous trench. This trench is then transferred onto the substrate to form precise patterns.
