EUV PHOTO MASKS AND MANUFACTURING METHOD THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 18214348 titled 'EUV PHOTO MASKS AND MANUFACTURING METHOD THEREOF

Simplified Explanation

The patent application describes a reflective mask used in various applications.

  • The mask consists of a substrate, a reflective multilayer, a capping layer, and an absorber layer.
  • The absorber layer is made up of alternating pairs of two different chromium (Cr) based layers.
  • The purpose of the mask is to reflect light and absorb specific wavelengths.
  • The innovation lies in the specific composition and arrangement of the absorber layer.
  • This reflective mask can be used in industries such as semiconductor manufacturing, lithography, and optical coatings.


Original Abstract Submitted

A reflective mask includes a substrate, a reflective multilayer disposed on the substrate, a capping layer disposed on the reflective multilayer, and an absorber layer disposed on the capping layer. The absorber layer includes one or more alternating pairs of a first Cr based layer and a second Cr based layer different from the first Cr based layer.
