Latest Patents

Liu's latest patents include an innovative apparatus for EUV lithography and a method of measuring focus. This method evaluates focus control by preparing a wafer exposed using the EUV lithography apparatus. The wafer contains test patterns formed of a photoresist, featuring circular islands or holes created through multiple exposures at varying foci. The process involves measuring a roughness parameter of these test patterns and estimating a function that represents the relationship between the roughness parameter and focus. By determining the best focus based on the extremum of this function, exposure wafers are then processed with optimal focus. The roughness parameter is periodically measured to identify any abnormalities in focus, ensuring high-quality lithography results.
