Latest Patents
William Johnson holds a patent for a "System and method for X-ray reflectometry measurement of low density films." This metrology system and method is designed to measure the thickness of thin films on semiconductor wafers. The system analyzes X-ray reflectivity data to determine the transmission characteristics of thin-film layers. Based on these characteristics, the thickness of the thin layer can be accurately determined. Unlike previous systems, this method does not rely on fringe patterns in reflectivity, which can be challenging to resolve in certain thicknesses of thin-film layers. This innovation is particularly advantageous in situations where traditional methods may fail.
