ABSTRACT:
A method of forming a device including a plurality of micron or sub-micron sized features is provided. A master having a surface contour defining a plurality of features is provided. The surface contour of the master is coated with at least one layer of material to form a shell. The master is removed from the shell to form a negative image of the surface contour in the shell. The negative image in the shell is filled with material, for example, polycarbonate, polyacrylic, or polystyrene, to form a device having features substantially the same as the master. The negative image may be filled using injection molding, compression molding, embossing or any other compatible technique.
