    • A method for calculating a process center for a chuck in a processing chamber is provided. The method includes generating pre-processing and post-processing measurement data points, which is perform by measuring thickness of a film substrate at a set of orientations and a set of distances from a geometric center of the substrate. The method also includes comparing the pre-processing and post-processing measurement data points to calculate a set of etch depth numbers. The method further includes generating etch profiles for the set of orientations. The method yet also includes extrapolating a set of radiuses, which is associated with a first etch depth, from the etch profiles. The method yet further includes generating an off-centered plot, which is a graphical representation of the set of radiuses versus the set of orientations. The method more over includes calculating the process center by applying a curve-fitting equation to the off-centered plot.

    • A bevel inspection module for capturing images of a substrate is provided. The module includes a rotational motor, which is attached to a substrate chuck and is configured to rotate the substrate chuck thereby allowing the substrate to revolve. The module further includes a camera and an optic enclosure, which is attached to the camera and is configured to rotate, enabling light to be directed toward the substrate. The camera is mounted from a camera mount, which is configured to enable the camera to rotate on a 180 degree plane allowing the camera to capture images of at least one of a top view, a bottom view, and a side view of the substrate. The module yet also includes a backlight arrangement, which is configured to provide illumination to the substrate, thereby enabling the camera to capture the images, which shows contrast between the substrate and a background.
    • 提供了一种用于捕获基板的图像的斜面检查模块。 模块包括旋转马达,其连接到基板卡盘并且构造成旋转基板卡盘,从而允许基板旋转。 该模块还包括照相机和光学外壳,其附接到相机并且被配置为旋转,使得光能够被引向基板。 照相机从照相机安装座安装,照相机安装件被配置为使照相机能够在180度平面上旋转,允许照相机拍摄基板的俯视图,底视图和侧视图中的至少一个的图像。 该模块还包括背光布置,其被配置为向基板提供照明,从而使得相机能够捕获显示基板和背景之间的对比度的图像。
