Abstract
Abstract Surface modification of polydimethylsiloxane (PDMS) under O 2 plasma exposure is studied by XPS and real time ellipsometry. Results show the conversion of the PDMS surface into a SiO x -like material. Total layer thickness and extension of the SiO x layer are controlled by the sample bias. We suggest that surface and line edge roughness defects occurring when using PDMS as top layer in bilayer lithography are intimately related to the rapid kinetics of conversion and to the formation of SiO x hard micromasks on the surface.
