摘要: A method of forming inspection patterns for inspecting a workpiece, e.g., for electron beam inspection of optical photomasks. The inspection patterns are formed from the workpiece patterns themselves by applying a first positive windage to the workpiece patterns, inverting the first positive windaged workpiece patterns and applying a second positive windage to the inverted first positive windaged workpiece patterns. The inspection patterns so produced will contain the requisite guard band and the requisite overlap of abutting patterns.
