Claim 16:
17. A method, comprising:
positioning a substrate of a first material in an apparatus, the apparatus including:
a chamber;
a collection container in the chamber; and
a support on the collection container, the support including:
a frame including an opening;
a plurality of arms extending from the frame into the opening; and
a seat within the opening,
each of the plurality of arms includes an upper portion delimited by a pair of upper inclined surfaces that intersect to form a vertex, and a lower portion delimited by a pair of lower inclined surfaces, the substrate being positioned in the seat;

forming a layer of a second material on the substrate, the layer of the second material having a first thickness;
separating a first portion of the substrate from the layer of the second material by melting the first portion of the substrate; and
forming the layer of the second material until the layer of the second material has a second thickness greater than the first thickness.
