Abstract

This paper describes work that has been done to develop X-ray contact printing of submicron gratings for integrated optical devices in our department. Previously, integrated optical devices, such as waveguide filters, have been made here using holographic exposure directly onto waveguide or semiconductor substrates. X-ray contact printing of holographically generated masks should make the fabrication of such devices simpler. The paper describes the work to date and gives fabrication details for the X-ray masks. X-ray contact printing is comparatively simple to perform, once the mask fabrication process is worked out. The paper describes our first results from the contact printer. In addition some results are presented on the manufacture of an X-ray mask for Quantum Dot structures.
