Abstract
A physically based model for full three-dimensional(3D)feature-scale simulation of ionized metal plasma (IMP) deposition has been implemented. It assumes a dynamical equilibrium of particle fluxes where the sum of delivering (positive ) and consuming (negative) fluxes is zero. This allows to calculate the de position rates of metal at the different positions on the feature surface. The simulator is validated by considering the quasi-2D case of a long trench and comparing the results with data from the literature. Vias are investigated by compar ing the profiles to the results for long trenches. Finally, the application to 3D structures without any symmetry is shown.
