Multi-Scale Transport Phenomena in Low-Pressure Plasmas
To account for the surface effects on the plasma behavior, a mesoscale Monte Carlo simulation has been developed which joins the die-scale surface chemistry with the plasma scale in the HPEM. The presence of etch products in the plasma is seen to perturb the bulk plasma. The presence of photoresist …

Modeling nanoscale transport phenomena: Implications for the continuum
Transport phenomena at the nanoscale can differ from that at the continuum because the large surface area to volume ratio significantly influences material properties. While the modeling of many such transport processes have been reported in the literature, a few examples exist that integrate …
