Abstract
Official abstract text for this publication.
Out-of-plane microneedle manufacturing process comprising the simultaneous creation of a network of microneedles and the creation of a polygonal shaped hat ( 2 ) above each microneedle ( 1 ) under formation, said process comprising the following steps: providing bridges ( 3 ) between the hats ( 3 ), maintaining the bridges ( 3 ) during the remaining microneedle manufacturing steps, removing the bridges ( 3 ), together with the hats ( 2 ), when the microneedles ( 1 ) are formed.
First claim
Opening claim text (preview).
1 - 12 . (canceled) 13 . A method of manufacturing a microneedle comprising the steps of: (i) patterning a protective mask to form an etch opening in the protective mask for etching a wafer, the wafer serving as material for the microneedle; (ii) first isotropic etching of an exposed area of the wafer at the etch opening to form a first cavity in the wafer; (iii) first anisotropic etching of the first cavity to define a head of the microneedle; (iv) second isotropic…
