    • The invention devices an inspection method, e.g. optical, which maximizes the sensitivity to mura effects and suppresses artifacts from the mura inspection hardware itself and from noise. It does so by scanning the sensor, e.g. a high- resolution camera, creating a region of high internal accuracy across the mura effects. One important example is for mura related to placement errors, where a stage with better than 10 nanometer precision within a 100 mm range is created. A sampling scheme reduces the data volume and separates between instrument errors and real defects based on their different geometrical signatures. The high- resolution camera scans sparse lines at an angle to the dominating directions of expected mura defects, creating extended sensor fields with high internal precision, and quantifying edge placements in small windows in said extended fields. The mura is classified and presented as type, location and severity.
    • 本发明装置检查方法,例如 光学,其最大限度地提高对mura效果的敏感性,并抑制mura检测硬件本身的伪影和噪声。 它通过扫描传感器,例如 一个高分辨率的摄像头,创造出一个高度内部准确度的区域在mura效果。 一个重要的例子就是与定位错误相关的mura,其中创建了100mm范围内优于10纳米精度的阶段。 采样方案可以减少数据量,并根据其不同的几何特征分离仪器误差和实际缺陷。 高分辨率摄像机以与预期的mura缺陷的主导方向成一定角度扫描稀疏线,创建具有高内部精度的扩展传感器场,以及在所述扩展场中的小窗口中量化边缘放置。 mura被分类并呈现为类型,位置和严重性。

    • The present invention relates to a method for writing a pattern on a surface of an object intended for use in exposure equipment, including the steps of: arranging an object having a thickness (T) provided with a surface on a stage of a pattern generating apparatus, dividing the surface into a number of measurement points, where two adjacent measurement points being spaced a distance (P) apart not exceeding a predetermined maximum distance, determining the gradient of the surface at each measurement point, calculating a 2-dimensional local offset (d) in the x-y plane for each measurement point as a function of the gradient, and the thickness (T) of object, and correcting the pattern to be written on said surface by using the 2-dimensional local offset (d). The invention also relates to a pattern generating apparatus, a method and an apparatus for measuring the physical properties of a surface of an object.
