SiO2 is hydrophilic. If you prime this surface with HMDS you will see a
dramatic effect.

Hello folks

Is there somebody who knows the way to check the quality of HMDS coated
on
SiO2.
 From the knowledge that I've collected so far, normally people try a
contact angle method, but
, as you know, SiO2 is also hydrophobic just like HMDS is.
I would like to check the qualify of HMDS, and the completeness of HMDS

monolayer coating onto the wafer as well.

Thanks in advance

Suyong
