chemical mechanical polishing vendor

[Choongho Yu]

Hi SNF members,

I am trying to find a vendor for a chemical and/or mechanical polishing of tiny samples.  The material of my sample is SrTiO3 and its size is 5 mm x 5 mm x 0.5 mm. I want to remove 100 nm top layer, but it is extremely difficult to remove 100 nm layer with smooth surface behind. HF leave a very rough surface and ion milling leaves a damaged surface.

I would appreciate if someone can send a name or contact information of the vendors.

Thank you.

C. Yu
