In a method for manufacturing a radiation window there is produced a layered structure where an etch stop layer exists between a carrier and a solid layer. A blank containing at least a part of each of the carrier, the etch stop layer, and the solid layer is attached to a radiation window frame. At least a part of what of the carrier was contained in the blank is removed, thus leaving a foil attached to the radiation window frame, wherein the foil contains at least a part of each of the etch stop layer and the solid layer.

For manufacturing a radiation window for an X-ray measurement apparatus, and etch stop layer is first produced on a polished surface of a carrier. A thin film deposition technique is used to produce a structural layer on an opposite side of said etch stop layer than said carrier. The combined structure comprising said carrier, said etch stop layer, and said structural layer is attached to a region around an opening in a support structure with said structural layer facing said support structure. The carrier is etched away.


A radiation window foil for an X-ray radiation window comprises a mesh that defines a number of openings (


A radiation window foil is provided for an X-ray radiation window. It includes a continuous window layer with a first side and a second side. A first mesh or grid layer is stacked on or bonded to the first side of the continuous window layer. A second mesh or grid layer is stacked on or bonded to the second side of the continuous window layer.

We have demonstrated the fabrication of ultra-thin Si fine grid supported silicon nitride X-ray windows. These X-ray windows exhibit unequaled transmission of soft X-rays, high strength and excellent thermal stability. Measured soft X-ray transmission performance is significantly enhanced compared to typical polymer or beryllium based X-ray window structures. A double sided grid structure is used to demonstrate the scaling of the technology to larger areas. © 1963-2012 IEEE. Source
