Abstract
A method for manufacturing particles includes depositing on a substrate a layer of a first sacrificial material; depositing on the layer of the first sacrificial material a layer of a second sacrificial material that is different from the first sacrificial material; forming cavities in the layer of the second sacrificial material, the forming including pressing a structured mold against the layer of second sacrificial material; depositing a material for manufacturing the particles, the material covering the layer of the second material and at least partially filling the cavities; selectively removing the second sacrificial material from the first sacrificial material so as to obtain the particles formed by the material and arranged on the layer of the first sacrificial material; and eliminating the first sacrificial material to release the particles.
