1. An embossing stamp, comprising:
a stamp substrate having a planar surface; two or more stamp structures formed on the stamp substrate having stamp surfaces extending from the stamp substrate to emboss a micro-channel in a layer, wherein at least one of the stamp surfaces forming the micro-channel is non-planar and incident-light-diffusive; portions of the embossing stamp between the stamp structures, wherein all of the portions have only flat and incident-light-non-diffusive surfaces; and wherein the stamp surfaces include one or more stamp side surfaces intersecting the stamp substrate and a stamp bottom surface intersecting a stamp side surface and not the stamp substrate.
