Electronics Produced by Roll-to-roll Self-Aligned Imprint Lithography

In this presentation, we present a method for fabrication using self-aligned imprint lithography (SAIL). The self-aligned process solves the layer-to-layer registration issues arising from the dimensionally changes of flexible substrates. The imprint process eliminates the need for photolithography and greatly lowers the cost for large area electronics because it is compatible with roll-to-roll processing. The basic concepts of the SAIL process are presented along with electrical characteristics of devices produced by roll-to-roll SAIL processes.
