Abstract

The conformal-evaporated-film-by-rotation (CEFR) technique, a bioreplication method to produce high-fidelity conformal coatings on biotemplates by oblique-angle deposition, was modified to improve the uniformity of coating thickness. The substrate holding the biotemplate was rocked, in addition to rotating it about an axis passing normally through it. With the compound eyes of the common blow fly as the biotemplate, quantitative comparison of coating thickness obtained by the original CEFR and the modified CEFR techniques showed the superiority of the latter.
