Previous photolithography technologies used transmissive masks protected by a pellicle. For EUV lithography, however, the masks must be reflective and cannot have a protective pellicle as this ...

Specifically, lithography is a planographic printmaking process ... and reflected off a series of mirrors before passing through the reticle (analogous to a mask in photolithography), which holds the ...

An image of a mask containing the structure of an integrated ... a disk measuring 300 mm in diameter. Interestingly, DUV lithography at a wavelength of 193 nm has dominated the field much longer ...

We could be implementing different reticle enhancement technology (RET ... The same is true for EUV lithography. For the mask, we need more resolution, maybe less than 20nm even on a 4X mask. We need ...

Nanostencil lithography (NSL) is a shadow-mask-based nanopatterning technique that allows for the direct deposition of materials through a stencil mask with nanoscale openings. It enables the ...

The mask is placed in a lithography tool. The tool projects light through the ... The stepper has a variable numerical aperture (NA) lens and 1X reticle. There are some challenges. During the RDL ...

The processing has been developed and demonstrated with an interferometric lithography tool. Ongoing work focuses on adapting this to projection tools though the use of new mask technologies.

For 3 decades, our products have been used by wafer fabs and fab equipment and materials suppliers to optimize and monitor lithography tool performance and processes. Benchmark also provides ...
