Formation of discontinuous films during an imprint lithography process
ActiveUS6932934B2Low viscosityMaterial nanotechnologyDecorative surface effectsLithography processLithographic artist
The present invention is directed to methods for patterning a substrate by imprint lithography. An imprint lithography method includes placing a curable liquid on a substrate. A template may be contacted with the curable liquid. Surface forces at the interface of the curable liquid and the template cause the curable liquid to gather in an area defined by a lower surface of the template. Alternately, the curable liquid may fill one or more relatively shallow recesses in the template and the area under the template lower surface. Activating light is applied to the curable liquid to form a patterned layer on the substrate.

An apparatus performing as a base for printing 3D objects using high temperature thermoplastics employing additive manufacturing methods is provided. The apparatus comprises a heated build platform, a thin removable plate secured on top of the build platform, a high temperature polymer coating applied over the removable plate, and surface treatment of high temperature polymer coating to maintain adhesion between 3D object and printing surface. Also, the removable plate has low coefficient of thermal expansion compared to build platform below it, for avoiding bowing of the plate as it is heated due to heated build platform, hence providing flat printing surface. The thin removable plate allows 3D objects to pop off the plate upon cooling, without damaging the polymer coating, the plate, or the object. It also allows for continuous operation of printing, while the plate is released for cooling, a new plate is installed for printing.
