Abstract

original image

Inspired by nature, a new strategy to create three-dimensional organic structures spanning orders of magnitude by using a combination of deep UV or X-ray direct lithography with a solid-state forming process. The stored latent lithographic image is transferred to three-dimensional curvilinear surfaces by forming the irradiated film under conditions of permanent material coherence.
