With a total of five patents to her name, her work has had a substantial impact on the industry.

Latest Patents

One of her latest patents is titled "Reactive preclean prior to metallization for sub-quarter micron application." This invention provides a precleaning process prior to metallization for submicron features on substrates. The method involves cleaning the submicron features with radicals from a plasma of a reactive gas such as oxygen, a mixture of CF/O, or a mixture of He/NF. The plasma is generated by a remote plasma source, and the radicals are delivered to a chamber where the substrate is located. Native oxides remaining in the submicron features are reduced in a second step by treatment with radicals from a plasma containing hydrogen. Following the precleaning steps, the features can be filled with metal using available metallization techniques, which typically include depositing a barrier/liner layer on exposed dielectric surfaces prior to the deposition of aluminum, copper, or tungsten. The precleaning and metallization steps can be conducted on available integrated processing platforms.
