Coating Al2O3 on a 150um Pt sphere
[Canada]
February 13, 2007
In my research I need to coat a Pt sphere with ~150um diameter
with a layer of Al2O3. The thickness of the coating is not critical,
as long as it can cover the Pt sphere. However, previous experience
shows the thickness cannot be more than 2um, otherwise it is easy to
be broken. Sputtering can do this kind of coating. The problem is how
to hold this tiny sphere. Some people use tape to hold this sphere.
After one side is coated, manully turn the sphere to other side and
coat it. It is grealy appreciated if any other ideas are given on
this problem.
