The key issues of cosmic-ray-induced softerror rates, SER (also referred to as singieevent upset, SEU, rates) in microeiectronic devices are discussed from the viewpoint of fundamental atomic and nuciear interactions between high-energy particles and semiconductors. From sea level to moderate altitudes, the cosmic ray spectrum is dominated by three particle species: nucleons (protons and neutrons), pions, and muons. The characteristic features of high-energy nuclear reactions of these particles with light elements are reviewed. A major cause of soft errors is identified to be the ionization electron-hole pairs induced by the secondary nuclear fragments produced in certain processes. These processes are the inelastic collisions between the cosmic ray particles and nuclei in the host material. A state-of-the-art nuclear spallation reaction model, NUSPA, is developed to simulate these reactions. This model is tested and validated by a large set of nuclear experiments. It is used to generate the crucial database for the soft-error simulators which are currently used throughout IBM for device and circuit analysis.

“…Hence the initial proton momentum was sampled from a distribution dP (p, θ, φ) ∝ (1+e (E−EF )/kT ) −1 p 2 sin(θ)dp dθ dφ (2) where a default Fermi energy E F corresponding to a momentum of p F = 220 MeV/c was used [30]. Quasifree me- son scattering experiments suggest [31,32,33] that owing to the fact that the pp annihilations happens in the periphery of the target nucleus at subsaturation density, significantly lower Fermi momenta may be expected. We therefore varied p F in the range of 180 to 260 MeV/c.…”

Exploring the potential of antihyperons in nuclei with antiprotons

A simple method to explore the interaction of antihyperons in nuclei by exclusive hyperon-antihyperon pair production close to threshold in antiproton nucleus interactions is proposed. Due to energy and momentum conservation event-by-event transverse momentum correlations of the produced hyperons and antihyperons contain information on the difference between their potentials. A schematic Monte Carlo simulation is used to illustrate the sensitivities of the proposed method for the reaction 1.66GeV/c antiproton+$^{12}$C $\to {\Lambda\bar{\Lambda}}$. For produced D-meson pairs at 6.7GeV/c the sensitivity of the transverse momenta correlation will probably be to small to deduce differences between the potentials for D$^+$ and D$^-$ mesons. However, for $\Xi\bar{\Xi}$ pairs produced at 2.9GeV/c the asymmetry is sufficiently sensitive to predicted differences between the $\Xi$ and $\bar{\Xi}$ potentials.Comment: updated references; several minor additions; format of figures modified for better representatio
