19 March 2018 Thin films for high-resolution, 3-color lithography
Author Affiliations +
Three-color lithography (3CL) can produce high-resolution features using visible light. This technique uses one beam to pre-activate a photoresist, a second beam to deactivate it, and a third beam to activate the pre-activated regions that have not been deactivated. The deactivation beam is used to trim features, allowing for improved feature size and resolution. Although this 3CL was pioneered with 2-photon excitation, the ultimate goal is to use thin films with linear excitation, such that it is compatible with industrial requirements. We will discuss the first thin-film 3CL studies, which are a promising step towards large-area patterning.
