Abstract:

During the 5 years of this contract, we used guided ion beam tandem mass spectrometric methods to study a variety of gas-phase ion-molecule reactions relevant to plasma deposition and etching of silicon. Absolute cross sections over a wide range of kinetic energies for reactions involving both atomic and polyatomic ions were measured. The results yielded energy dependent cross sections, temperature dependent rate constants, and thermochemical data, information vital to further understanding of the chemical mechanisms involved in plasma processing. Ion-molecule reaction rates, Plasma etching, Plasma deposition, Ion-molecule cross sections.
