Summary

In summary, we find it is possible to model the extent of arsenic diffusion during front-end and back-end processes that define the final junction depth. The key features of the model can be summarised as: (a) Interstitials from implant damage play a diminished role as implant energies are scaled; (b) As4V formation and precipitation at high concentrations is critical to accurate modeling of ultra-shallow arsenic junctions. These models when used with device simulations help optimize transistor performance/tradeoffs.

We would like to thank Pavel Fastenko and Scott T. Dunham (University of Washington) for details and discussion regarding their modeling results.
