DECISION ON APPEAL
This is a decision on an appeal which involves claims 1-3, 7, 11-13, 15, 17, and 19-23.
The subject matter on appeal relates to a method of producing a structured layer (e.g., an
electrode for a storage capacitor of an integrated memory device; see specification, page 1). The
method comprises applying a precious metal and a donor material containing an additive onto a
prestructured substrate in two or more layers, heating the layers between approximately 400°C –
800°C so that the additive diffuses into the precious metal to form an alloy layer, and polishing
the alloy layer by chemical and mechanical means. See specification, page 6. This appealed
subject matter is adequately represented by independent claim 1, which reads as follows:
