Latest Patents

Ippolito's latest patents include a method and apparatus for probing a wafer. This invention involves a semiconductor wafer resting on a contact element, where a spatially distributed force is applied to its frontside and an equal and opposing force is applied to its backside. The contact element comprises a solid immersion lens (SIL) and has an area less than that of the wafer, but no less than the larger of the area of an optical collection area and an electrical probe assembly. The forces cause the wafer to conform to the shape of the contact element, allowing for measurements, including electrical testing, optical probing, and wafer characterization.

Another significant patent is related to angular spectrum tailoring in solid immersion microscopy for circuit analysis. This invention provides a structure for locating faults in a semiconductor chip. The chip includes a substrate on a dielectric interconnect, and the method overlays electrical response images on reflection images for monochromatic light. This innovative approach helps determine the location of faults within the chip, enhancing the reliability of semiconductor devices.
