Latest Patents

Ron Lopez holds a patent for an "In-line focus monitor structure and method using top-down SEM." This invention relates to a test structure formed on a reticle simultaneously with a pattern used to build an integrated circuit device. The test structure features a large rectangular end with several rectangular shapes extending in a parallel array. The width of these extensions matches the spacing between them and corresponds to the minimum feature size in the lithographic process being monitored. A CD SEM is utilized to measure the edge width of the convex and concave sections of the structure as printed in photoresist at various focus settings. The resulting plot of edge width versus focus setting helps identify the optimal focus setting for the lithographic process.
