Atomic Structure of Wet Oxidized Silicon

Hello everyone,

I would like to buy some Si wafer with SiO2 layer on it. The manufacturer told me that they obtain the SiO2 with a wet oxidation process.

My question is, would this layer be amorphous or crystalline or polycrystalline?

Thanks!

You'll have to ask the manufacturer.

The wet oxide layer is amorphous (glassy) like fused silica. Consist of regular silicon-oxide tetrahedrons, mostly making 6-member rings, like in cristobalite, but without long-range order.
