Latest Patents
One of her latest patents is titled "Method for constructing contact formations." This invention outlines a method for forming contact formations by placing a substrate in an electrolytic solution. The substrate features an exposed conductive portion, while the electrolytic solution contains a variety of metallic ions and an accelerator. The accelerator may include compounds such as bis-(sodium sulfopropyl)-disulfide and 3-mercapto-1-propanesulfonic acid-sodium salt. By applying a voltage across the electrolytic solution and the conductive portion, metallic ions are transformed into metallic particles and deposited on the substrate. The solution may also incorporate a protonated organic additive, an acid, and a surfactant to optimize the process.
Another notable patent is for an "Under bump metallization layer to enable use of high tin content solder bumps." This invention describes an apparatus and methods for fabricating an under bump metallization structure. It includes an adhesion layer, a molybdenum-containing barrier layer, a wetting layer, and high tin content solder material. The molybdenum-containing barrier layer is crucial as it prevents the migration of tin in the solder material, which could lead to delamination or damage to underlying structures.
