The invention is a low cost manufacturing process for micro and nanoporous filter membranes with highly uniform, high density arrays of regularly spaced pores.
Significantly less expensive than films on solid substrates. Provides a process for manufacturing large area filter membranes from polymeric sheet stock without the need of a flat solid substrate or of assembling small filters to form a single large filter.
Very large market. For example, the invention can be used in the manufacture of integrated circuits (ICs).
