Abstract
Disclosed is a device for making multi-layer crystals. It includes a holder and a plurality of masking elements adapted to be secured successively to the holder. The masking elements have cover pieces that overlie the area protected by the preceding cover pieces and have an additional cover piece. This produces a device having progressively truncated corner sections. There is thus formed a multi-layered crystal having portions adapted to be connected to electrical leads.
