Structure with a silicon body having through openings
First Claim
1. A structure for modifying energetic radiation comprising a silicon body having a through hole defining a passage for said energetic radiation;
- and a layer of heavy metal silicide covering the surface of said silicon body, whereby said metal silicide layer maintains good adherence to said silicon body under thermal stress, and said metal silicide layer absorbs said energetic radiation except in said defined passage by way of said through hole.

Abstract
A structure for shaping or masking energetic radiation is described. The structure comprises a shallow silicon body having at least one through opening, and a metal silicide layer covering the surface of the structure. The structure characterized by having a high mechanical, and thermal stability may be used particularly in electron and X-ray lithography. More specifically, the structure may be used as an aperture for electron beams, or as a mask for X-rays. The production of the structure includes the steps of making through openings in the silicon body, and the forming of the silicide layer by vapor depositing a metal on the surface of the silicon body and by subsequent annealing.
