Correlation is made between the effects of displacement damage caused in several types of silicon bipolar transistors by protons, deuterons, helium ions, and by 1 MeV equivalent neutrons. These measurements are compared to calculations of the nonionizing energy deposition in silicon as a function of particle type and energy. The main conclusions of the work are as follows: 1) The ratio of the displacement damage factors for a given charged particle to the 1 MeV equivalent neutron damage factor, as a function of energy, falls on a common curve which is independent of collector current. 2) Deuterons of a given energy are about twice as damaging as protons and helium ions are about eighteen times as damaging as protons. 3) The ratios of the calculated nonionizing energy deposition in silicon by protons, deuterons, and helium ions as a function of energy to the calculated nonionizing energy deposition by 1 MeV neutrons, agree exactly with the experimental damage factor ratios over the whole energy range considered, with no fitted parameters. 4) This agreement means that there is a linear dependence of the experimental displacement damage factors on nonionizing energy deposition for all particles (including neutrons) and for all energies. 5) Therefore, the damage factors for different particles are directly proportional to the number of defects originally produced, are not affected by defect cascades, and are independent of the PKA spectrum.
