Abstract
A micro-needle array having tips disposed along a non-planar surface is formed by shaping the wafer surface into a non-planar surface to define the tips of the micro-needles. A plurality of trenches are cut into the wafer to form a plurality of columns having tops corresponding to the non-planar surface. The columns are rounded and sharpened by etching to form the micro-needles.
