We get alumina substrates from Coorstek, they have 100 mm disks.
http://www.coorstek.com/resource-library/library/8510-1041_thin_film_design_guide.pdf
A company that can deposit (DVM) the TiO2 is likely to be able to sputter
or DVM the Pt. A lot of smaller companies would do this for you, but
you'll have to pay for a whole chamber run for both materials, and that's
expensive.
Google < DVM TiO2 > and call them.

Syed,
(1) most likely you not going to get a wafer but a plate of alumina
(square not round). It just nature of the beast of ceramic.
(2) most likely, you are going to get a alumina with glazed surface - sio2
rich layer with smooth surface - you need to look at substrate supplier
that specialize LTCC or high temperature/high power device ceramic
substrate.
(3) as for TiO2 and Pt metallization, you might have to go to 3rd party
house to specially made. Pt is easy - your school electron microscopy
facility may have SEM sputter coater that uses Pt. As for TiO2, you are
looking at specialized service. Most likely, you are not going to get a
quote from one place that provide you with all of the stuff you want. For
qty of 5 pieces, you better try some national research lab, see if anyone
would do a special job without burn a hole in your pocket. (The semi
house that have everything would never provide you with a special run that
potentially contaminate their chamber).
My 2 cents.

Subject: [TN] need alumina wafers
Dear TechNet Denizens,
We are in need of 5 ea. 100 mm alumina wafers. To add to that it would
be beneficial if someone could quote us 5 100 mm alumina wafers with a
SiO2 layer, TiO2 layer followed by a Pt layer. If you are able to
accomplish this please email back and contact us. It will also help if
sources can be referenced.
Thank you for your help.
