Step and Stamp Imprint Lithography
As the semiconductor industry continues to push to smaller device geometries, lithography becomes more and more a crucial process step. Traditionally, the semiconductor industry has relied on optical lithography and new generations of optical steppers are being developed for shorter wavelengths. Anyhow, in order to produce sub-50 nm lithography researches have started to look for new solutions, such as X-ray lithography, fast electron beam (e-beam) lithography and nanoimprint lithography (NIL).
