Latest Patents

Graupp's latest patents focus on innovative design methodologies aimed at improving the reliability of integrated circuit joints. One of his patents presents a design methodology that reduces electromigration in flip-chip bumps by creating a more uniform current distribution at the interface between the integrated circuit pad and the joint. This is achieved by introducing an intermediate trace routing design that connects the current delivering trace to multiple points of entry on the pad. The design includes an outer trace channel and a plurality of conductive trace leads, each characterized by respective trace impedance to ensure equal current flow.

Another patent introduces a novel pad structure for integrated circuit components that utilizes a bump interconnect. This design aims to produce a relatively uniform current distribution within the bump, enhancing the performance and longevity of the interconnect. The pad structure features an inner pad on a conductive layer, an outer pad on another layer, and a series of vias connecting the two pads. The outer pad is sealed with a passivation layer, ensuring durability and reliability in various applications.
