Title: The Innovations of Charles William Lentz
Introduction
Charles William Lentz is an accomplished inventor based in Lower Heidelberg Township, PA. He is known for his significant contributions to the field of wafer thinning technology. With a focus on enhancing measurement techniques, Lentz has developed innovative solutions that improve efficiency and accuracy in semiconductor manufacturing.
Latest Patents
Lentz 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. By integrating an optical reflectometer into a common wafer thinning apparatus, the system utilizes reflected optical signals from both the top and bottom of the wafer. This allows for real-time thickness determination through time-based calculations during the thinning process. Once the desired thickness is achieved, the thinning operation is halted. This in-situ measurement approach 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.
