Yes you need to Silylate the first resist. The Silicon barrier you set
up will stop the second resist solvent dissolving the first resist.

Subject: [mems-talk] Double lithography problem with SU1828-TI35ES
Hello everyone,
I am making lithography with SU1828. After patterning of this resist, i
need to make a another lithography on top of SU1828's patterns, but when
i spin to other resist (TI35ES) the solvent of TI35ES dissolves to
patterns of SU1828.
Do you have similar experience?
