According to one aspect of the invention, there is provided a method of forming a film with a lenticular lens array, the method comprising providing a substrate; providing a mold having a plurality of nano-scale to micro-scale cavities that form the lenticular lens array on the substrate; having the mold contact the substrate; and forming the lenticular lens array by allowing portions of the substrate to partially fill the plurality of cavities.

A method for fabrication of high electron mobility transistor (HEMT) semiconductor devices is presented. The method includes providing a substrate, growing a HEMT layer structure on the substrate; and self-aligned common metal stack formation of source, drain and gate electrodes on the HEMT layer structure using a single lithographic mask.

For forming a nickel mold, a metal and a corresponding etchant are selected such that the etchant selectively etches the metal over nickel. The metal is sputtered onto a surface of a template having nano-structures to form a sacrificial layer covering the nano-structures. Nickel is electroplated onto the sacrificial layer to form a nickel mold, but leaving a portion of the sacrificial layer exposed. The sacrificial layer is contacted with the etchant through the exposed portion of the sacrificial layer to etch away the sacrificial layer until the nickel mold is separated from the template. Subsequently, the nickel mold may be replicated or scaled-up to produce a replicate mold by electroplating, where the replicate mold has nano-structures that match the nano-structures on the template. The metal may be copper.
