Latest Patents
One of Johnson's latest patents is titled "Localized heating for defect isolation during die operation." This invention provides a system for testing a semiconductor die, which has circuitry on one side and silicon on the opposite side. The opposite side may be anti-reflective coated and is thinned to allow for effective testing. By powering the die and heating a portion of the circuitry, Johnson's system can induce a reaction in a target region, enabling the detection and analysis of circuit failures or recoveries.
Another significant patent is "Method of substrate silicon removal for integrated circuit devices." This invention addresses the etching process of an integrated circuit die that is coupled to a package substrate. Johnson's method inhibits the erosion of underfill material used around the die's periphery. By forming a protective coating over the underfill material, he allows for the use of etch chemistries that would otherwise harm the die, thus preventing issues such as die chipping.
