Abstract: Hexamethyldisilazane (HMDS) is utilized to deposit moisture barrier films by catalytic chemical vapor deposition (Cat-CVD). An increase in the thickness of silicon oxynitride (SiO_xN_y) films leads to a better water-vapor transmission rate (WVTR), indicating that Cat-CVD SiO_xN_y films deposited using HMDS do not severely suffer from cracking. A WVTR on the order of 10^<-3> gm^<-2>day^<-1> can be realized by a Cat-CVD SiO_xN_y film formed using HMDS on a poly(ethylene terephthalate) (PET) substrate without any stacking structures at a substrate temperature of as low as 60 ℃. X-ray reflectivity (XRR) measurement reveals that a film density of >2.0 g/cm^3 is necessary for SiO_xN_y films to demonstrate an effective moisture barrier ability. The use of HMDS will give us safer production of moisture barrier films because of its non-explosive and non-toxic nature.
