Latest Patents

One of her latest patents is titled "Method for preventing metalorganic precursor penetration into porous dielectrics." This invention provides methods and structures for conformal lining of dual damascene structures in semiconductor devices that contain porous or low k dielectrics. The process involves forming features such as trenches and contact vias in the dielectrics, which are subjected to low-power plasma predeposition treatment. This treatment addresses irregularities on the porous surfaces and forms a permeation barrier before a diffusion barrier material is deposited. The feature is then filled with copper metal, enhancing the dual damascene interconnect process.

Another notable patent is "Method to improve barrier layer adhesion." This invention offers a method to enhance the adhesion of barrier, metal, and dielectric interfaces. In this process, a first barrier material is formed on a dielectric layer and bombarded with plasma to effectively push the barrier material into the dielectric interface. A second barrier material is then formed on the remaining first barrier material, ensuring excellent adhesion and preventing chemical mechanical polishing delamination.
