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
