The only company that I have heard of that is doing wafers this thin is
Valley Design http://www.valleydesign.com They had told me in the past
that they could handle a 23um request that I had at the time. I know
that their thin wafers are shipped attached to their mounting medium
(not sure what it is).
I know of several that can do 50um, but 5-20 is well beyond their
capability.
