Claim 32:
33. A method for manufacturing an apparatus, comprising: providing a substrate comprising a recess; introducing a multitude of particles into the recess; coating a first portion of the multitude of particles so that the first portion is joined to a porous structure by using a coating process comprising a penetration depth proceeding from an opening of the recess along a depth direction into the recess; and wherein the penetration depth of the coating process into the recess is set such that a second portion of the particles is not joined by means of the coating and such that the first portion of the particles is arranged between the second portion of the particles and a surrounding area of the recess and such that a movement of the second portion of the particles towards the surrounding area of the recess is essentially prevented; wherein the coating is performed by means of chemical vapor deposition, atomic layer deposition or atomic vapor deposition.
