Thin film diffusion barrier formation in PDMS microcavities [PDF]
, 2009 We describe a method to form glass like thin film barrier in polydimethylsiloxane (PDMS) microcavities. The reactive fragments for the surface reaction were created from O2 and hexamethyldisiloxane (HMDS) in RF plasma environment.
