Abstract:
1. A method for forming a semi-transparent imprinting template, the method comprising: applying a first material, having at least one organic material layer, onto a seed layer disposed on a first support surface; forming a relief pattern on the organic material layer; selectively removing material from the thinnest portions of the relief pattern of the organic material layer, wherein the seed layer is exposed through the openings formed in the relief pattern; depositing onto the seed layer an opaque second material by electrodeposition or electroless deposition; adhesively bonding a transparent upper support layer to the relief pattern containing the second material, wherein the adhesive and upper support layer are optically transparent; separating the deposited material, that is bonded to the upper support layer, from the first support surface; and forming a semi-transparent relief pattern by removing an amount of the first organic material.
