Abstract:
An x-ray inspection system comprising: a cabinet (110), the cabinet (110) containing an x-ray source (100), a sample support (200) for supporting a sample to be inspected, and an x-ray detector (300); an air mover (130) configured to force air into the cabinet (110) through an air inlet (132) in the cabinet (110) above the sample support (200), wherein the air mover (130) and cabinet (110) are configured to force air through the cabinet (110) from the air inlet (132) past the sample support (200) to an air outlet (150) in the cabinet (110) below the sample support (200), and a sample support positioning assembly (310) for positioning the sample support (200) relative to the x-ray source (100) and x-ray detector (300); wherein the sample support (200) comprises an upper surface extending in a horizontal plane and wherein the sample positioning assembly (210) comprises a vertical positioning mechanism (214, 216) for moving the sample support in a vertical direction, orthogonal to the horizontal plane, and a first horizontal positioning mechanism (212, 214) for moving both the sample support (200) and the vertical positioning mechanism (214, 216) in a first horizontal direction.

An x-ray inspection system comprising: an x-ray source (100), a sample support (200) for supporting a sample to be inspected, an x-ray detector (300), a sample positioning assembly (210) including a first positioning mechanism (210) for moving the sample support (200) along a first axis towards and away from the x-ray source (100), a proximity sensor (400) fixed to the x-ray source (100) configured to provide a measurement of distance between the x-ray source (100) and a surface of a sample on the sample support (200); and a controller (500) connected to the proximity sensor (400). Measurements from the proximity sensor (400) can be used in image processing calculations and to prevent collision between a sample and the x-ray source (100).
Abstract:
The invention relates to a sensor system (PSS) configured to determine a position of a substrate (W) having an edge (WE). The sensor system comprises a radiation source (LS) arranged to emit a radiation bundle (LB), a reflective element (RE), a detector device (DD) and a substrate table (PWT) having a supporting surface for supporting the substrate. The supporting surface is at least partly along a plane. The radiation source and the detector device are arranged on a first side of the plane. The reflective element is arranged on a second side of the plane other than the first side. The reflective element is arranged to create a reflected bundle by reflecting the radiation bundle. The reflective element is arranged to illuminate the edge with the reflected bundle. The detector device is arranged to receive the reflected bundle.
