Deposition masks - Shadow masks
Deposition masks are used for PVD-processes (sputtering, vapor deposition)
The shadow masks are applied e.g. for the deposition of metal electrodes on polymer, glass or ceramic substrates. The PVD-process allows also the deposition of patterned oxidic insolation layers via shadow masks.
With the increasing requirements on precision and structure resolution, electroformed masks become more and more important. Electroformed shadow masks are characterized by vertical, burr-free edges with a low surface roughness. The Nickel made shadow masks can be magnetically fixed on a substrate ensuring a good contact over the whole surface.
