Résumé     
The purpose of this paper is the characterization of a plasma-doping system in BF3. Energy distributions (IEDs) of boron ions crossing a high-voltage sheath (up to 1 kV) are measured in a BF3 plasma under different experimental conditions. It is demonstrated that relative percentages of boron ions reaching the cathode and IED shapes are governed by the number of collisions inside the sheath. Heavy molecular ions (B2F5+, B2F3+) are dissociated inside the sheath and light boron ions (B+, BF+) are created. Based on experimental results and ab initio calculations of boron ion structures, the mechanisms occurring in the sheath are discussed. Furthermore, the charge exchange cross-section between BF3+ and BF3 is estimated to be 8.8 x 10(-19) m(2).
