The vapor species present in the deposition chamber during the vapor deposition of poly-para-xylylene (Parylene) thin films was analyzed using a differentially pumped quadrupole mass spectrometer (DPQMS). The partial pressure in the deposition chamber of volatile contamination originating in the dimer source, di-para-xylylene, was determined. The magnitude of the contamination was determined and its mass spectrum was analyzed using the DPQMS. Fragmentation patterns for the monomer were determined as a function of quadruple mass spectrometer (QMS) ionizing electron energy for energies ranging from 25 to 105 eV.
