Abstract
Channeling and backscattering measurements with 3.8 MeV He-4 analysis beams have been used to determine the C/Si stoichiometric ratio in 100 -200 nm SiCx(H-y) films deposited on (100) Si substrates by plasma-enh anced CVD using gas mixtures of CH4 and SiH4. The results show that bo th annealed and unannealed films are amorphous and allow determination of the C/Si ratio to better than +/-10% for 0.2 < x < 1.0. Film hydro gen content was determined by ERD with 3.5 MeV He-4 analysis beams. In addition, potential problems associated with the use of the 4.265 MeV He-4-C resonance to quantify C in Si are discussed.
