Abstract

A filter window manufacturing method includes fabricating a structure of wires on a substrate, depositing a lacquer over the wires and the substrate, depositing a first layer that includes a material selected from the group consisting of AlN, Ru, Ir, Au, SiN, Rh, C and combinations thereof, removing the lacquer, removing the substrate, and baking the first layer.

Claims

1. A filter window manufacturing method, comprising:

fabricating a structure of wires on a substrate;

depositing a lacquer over the wires and the substrate;

depositing a first layer comprising a material selected from the group consisting of AlN, Ru, Ir, Au, SiN, Rh, C and combinations thereof;

removing said lacquer;

removing said substrate, and

baking said first layer.

2. A filter window manufacturing method as in claim 1, wherein said removing said lacquer comprises heating to vaporize said lacquer.

3. A filter window manufacturing method according to claim 1, further comprising:

fabricating a second layer comprising a material selected from the group consisting of Si, Be, B₄C, Mo, Zr, Nb, C, Al and combinations thereof; and

depositing a third layer comprising a material selected from the group consisting of AlN, Ru, Ir, Au, SiN, Rh, C and combinations thereof.

4. A filter window manufacturing method comprising:

depositing, onto a substrate soluble in a fluid, a first layer comprising a material selected from the group consisting of AlN, Ru, Ir, Au, SiN, Rh, C and combinations thereof;

dissolving said substrate in the fluid;

removing said first layer from the fluid by adhering said first layer to a wire structure; and

baking said first layer.

5. A filter window manufacturing method according to claim 4, further comprising:

fabricating a second layer comprising a material selected from the group consisting of Si, Be, B₄C, Mo, Zr, Nb, C, Al and combinations thereof; and

depositing a third layer comprising a material selected from the group consisting of AlN, Ru, Ir, Au, SiN, Rh, C and combinations thereof.

6. A filter window manufacturing method according to claim 5, wherein said fabricating said second layer comprises fabricating a base layer and elevated bars on top of said base layer.
