Lithographic template and method of formation and use
TL;DR: In this paper, a lithographic template is used in the fabrication of a semiconductor device for affecting a pattern in the device by positioning the template in close proximity to the semiconductor devices having a radiation sensitive material formed thereon and applying a pressure to cause the radiation-sensitive material to flow into the relief image present on the template.

Laser assisted direct imprint lithography
TL;DR: In this paper, features can be directly imprinted into the surface of a solid substrate by the steps of providing a mold (20) having a molding surface (21) to imprint the pattern, disposing the molding surfaces adjacent or against the substrate (24) surface (25) to be imprinted, and irradiating the substrate surface with radiation to soften or liquefy the surface.

Ultraviolet Laser Ablation of Organic Polymer Films
TL;DR: When a pulse (~ 14 nsec half width) of laser radiation of 193 nm wavelength with a fluence above a threshold value falls on a polymer film, the material at the irradiation site is spontaneously etched away to a depth of 1000 A or more.
