Abstract
A microneedle structure has one or more microneedles () projecting from the major surface () of a substrate (). The microneedle has a penetrating tip () formed at an intersection between upright surfaces () and an inclined surface () corresponding to a (1 1 1) crystallographic plane. The microneedle has an expanding portion bounded by a continuation of the upright surfaces () and inclined surface (), and a constant cross-section portion bounded by a continuation of the upright surfaces and a slicing plane () extending from an edge () of inclined surface () towards, and perpendicular to, major surface () of the substrate. A width W of inclined surface () increases monotonically from penetrating tip () to edge ().
