Problem with oxygen plasma bonding of two pdms slabs

Hi all!
I've been trying to bond two pdms devices using an oxygen plasma source.
It seems that the plasma system can effectively bond two untreated pdms slabs,
but the problem is...
I have to coat my patterned wafer with silane as it has small pit/trench
features.
After slicing up my pdms slabs, I immediately tried bonding these two slabs
together but without success.
The plasma system has no problem in bonding two untreated pdms slabs, so I
anticipate that the silane has rendered the pdms hydrophobic, leading to a
failure in bonding.
Is there a way to remove the silane coated pdms, after peeling it off from my
wafer, to enhance the bonding strength?
Thank you!
Best,
TJ
