Latest Patents
Wan-ning Wu holds a patent for an invention titled "In-situ automated contactless thickness measurement for wafer thinning." This system is designed to measure the thickness of a wafer while it is being thinned. The method integrates an optical reflectometer into a common wafer thinning apparatus. By utilizing reflected optical signals from both the top and bottom of the wafer, the system determines the thickness in real-time during the thinning process. Once the desired thickness is achieved, the thinning operation is halted. This in-situ measurement prevents the scrapping of overthinned wafers and eliminates the need to reload wafers that are too thick. The contactless nature of the optical reflectometer also ensures that wafers are not damaged during measurement.
