Subject: [mems-talk] SoI wafer holders

Hi,

I bought few SOI wafers from UltraSil. They have come in one white
colored
cassette like a wafer holder with slots. I am wondering if that wafer
holder
is Teflon coated or acid resistant. Can anyone tell me how to identify
that?

Thank you,

Nikhil Sheth
