Fabrication of plasmonic structures with well-controlled nanometric features: a comparison between lift-off and ion beam etching

Olivier Martin, Christian Santschi, Banafsheh Abasahl

After providing a detailed overview of nanofabrication techniques for plasmonics, we discuss in detail two different approaches for the fabrication of metallic nanostructures based on e-beam lithography. The first approach relies on a negative e-beam resis ...

Limitations of Proximity Lithography Printing : Simulations, Experiments, and Applications

Krishnaparvathy Puthankovilakam

Photolithography is one of the earliest technologies used to transfer patterns to a substrate. It is also known as optical lithography since it uses light to transfer the pattern. The main exposure techniques exist in the industry are projection printing, ...

Stencil assisted reactive ion etching for micro and nano patterning

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart

Stencil-assisted oxygen reactive ion etching is a low-cost and parallel process for the replication of micrometric and nanometric patterns in any organic material. This lithography process allows the patterning of organic material non sensitive to electron ...
