Latest Patents
One of Richard's latest patents is titled "Method for fabrication of probe card for testing of semiconductor devices." This invention utilizes a flexible polyimide film to support an array of precisely located contact bumps, which are essential for probing die on a wafer of semiconductor circuits. By employing a standard I/O contact pattern and fabricating the membrane assembly of interconnects on an aluminum substrate, Richard's method enhances the reliability of probe cards while reducing fabrication time and costs. The selection of polyimide film with a coefficient of thermal expansion (CTE) of 3 to 5 is crucial, as it creates a critical degree of compressive stress, resulting in a 'bow' of the film when the aluminum substrate is etched away.
Another significant patent is the "Non-destructive burn-in test socket for integrated circuit die." This invention provides a temporary packaging solution for integrated circuit die, multichip hybrids, or complete wafers without damaging the bonding pads or insulating passivation during testing and burn-in processes.
