Abstract
An apparatus includes a substrate having a recess and a multitude of particles arranged in the recess. A first portion of the particles is joined to a porous structure by means of a coating. A second portion of the particles is not joined by means of the coating. The first portion of the particles is arranged closer to an opening of the recess than the second portion of the particles so that a leaking of the second portion of the particles from the recess through the opening is prevented.
