Soft Lithography – A Low Cost, Production Method For Producing Nano Sized Features Even On Curved Surfaces

Abstract:
Soft lithography is so called because it utilises cast moulded stamps made from flexible materials.

The process begins with the creation of a master. The master is made by etching a blank - normally a silicon wafer - with a negative photoresist. This gives a raised pattern of nanometer sized features on the silicon wafer that corresponds with the required channels in the polymer stamp.
