DEVICE WITH A PLURALITY OF PARTICLES, AND METHOD FOR PRODUCING SAME

摘要

The invention relates to a device (10) comprising a substrate (12), which has a recess (14), and a plurality of particles, which are arranged in the recess (14). A first portion of the particles (16) is connected by means of a coating so as to form a porous structure (22), and a second portion of the particles (18) is not connected by means of the coating. The first portion of particles (16) is arranged closer to an opening (19) of the recess (14) than the second portion of particles (18) such that a loosening of the second portion of particles (18) out of the recess (14) through the opening (19) is prevented.
