摘要：

Reported depth profiles of hydrogen (deuterium) in silicon, created by exposure to plasma, were re-analysed on the basis of modern knowledge of the properties of atomic and dimeric hydrogen species. In boron-doped samples, the profiles allow to extract the equilibrium constant for the boron passivation reaction and the binding energy of the HB defect, 0.75eV. In the near-intrinsic samples the profiles shape suggests two independent in-diffusion and pairing processes: one is by fast dimers, and the other - by neutral monomers that are reversibly trapped by some impurity, probably carbon.
