<p>The manufacture a single/multi layered metallic structure using lithography, electroforming and molding ultraviolet technology, comprises spreading out a photoresist layer on a massive metallic substrate, creating a photoresist mold by irradiation/electronic/ionic bombardment, heating the photoresist layer for evaporating a solvent, exposing the photoresist layer through a mask corresponding to desired imprint under an ultraviolet radiation of 100-2000 mJ/cm 2> measured at a wavelength of 365 nm, and annealing the layer for complete photopolymerization/photodecomposition.

The massive metallic substrate has a textured upper surface with micro-beading, mechanical-chemical etching or laser, and a polished upper surface in which the substrate is made up of stainless steel. An independent claim is included for a processed metallic structure.</p> |
