The beginning of the thermalization is very similar to the one in bulk material, but the weakness of the capture rate is responsible for a carrier bottleneck at the top of the well. The overall relaxation time appears very sensitive to detailed structure parameters, as the well thickness and the optical confinement layer width.","PeriodicalId":106774,"journal":{"name":"RADECS 97.

The degradation of the electrical and optical performance of diodes increases with increasing fluence. In the In/sub 0.53/Ga/sub 0.47/As epitaxial layers, hole and electron capture levels are induced by irradiation. The influence of the radiation source on the degradation and recovery is then discussed by comparison to 1-MeV electrons and 1-MeV fast neutrons with respect to the numbers of knock-on atoms and the nonionizing energy loss (NIEL). Isochronal thermal annealing for temperatures ranging from 75 to 300/spl deg/C shows that the device performance degraded by the irradiation recovers by thermal annealing, and that the recovery behavior has a radiation source dependence. The recovery increases with increasing annealing temperature. The amount of recovery for alpha rays is nearly the same as for neutron irradiation, while that for electron irradiation is much larger. The radiation source dependence of performance degradation is attributed to the difference of mass and the probability of nuclear collision for the formation of lattice defects.","PeriodicalId":106774,"journal":{"name":"RADECS 97.

Degradation processes by injected carriers are related to the insulating oxide edge defects in the gate to drain overlap region.

In this paper, we present new experimental evidence of latent interface-trap buildup in commercial power VDMOSFETs: its dependencies on dose, temperature and gate bias applied during irradiation and annealing. We discuss several models for latent interface-trap buildup and show that the most consistent is one which involves the diffusion of molecular hydrogen from structures adjacent to the gate oxide (CVD oxide, poly-Si gate), and its cracking on positive charge centers in the oxide. The cracking reaction liberates hydrogen ions, which drift to the Si/SiO/sub 2/ interface to form interface traps. Some hypothesis from the recently proposed H-W model for post-irradiation behavior of interface traps may help resolve the question of the source of hydrogen sufficient to cause up to 800% increase in interface-trap density, experimentally observed. The implications of latent interface-trap generation for hardness assurance test methods are also discussed.","PeriodicalId":106774,"journal":{"name":"RADECS 97.
