scrap 6" wafers

[Vincenzo Lordi]

Hello,

I'm seeking donation of any scrap 6" wafers that consist of a
finely-patterned blanket metal film as the top layer. Any pattern is
acceptable, with feature sizes down to 1um preferable. Bare aluminum
is not preferred (although may be acceptable); passivated Al or metals
with conducting native oxides are better.

I appreciate any help you can provide.
