Abstract :
This article was written to understand a comment that was given at the Question and Answer period of a paper presented at ESREF 96 in Enschede, The Netherlands, last October. The question was: “Your model includes only temperature and electric field in dielectric breakdown. We are able to break oxides with no field at all (i.e. with hot carriers). How can you explain that?” This study was conducted to simply calculate the likelihood of breaking Si-O bonds with hot carriers. The calculations indicate that while it is possible for hot carriers to populate traps causing voltage threshold shifting, it is not possible to break an oxide with hot carriers
