The proposed model is compared to the models of Jallepalli et al. (1997) and Kamakura et al. (2000). It is demonstrated that the inclusion of data sensitive to the high energy part of the hole distribution function points out that previously proposed models are not able to reproduce experimental data when very high fields are present, and allows to find more accurate scattering rates.","PeriodicalId":220325,"journal":{"name":"International Conference on Simulation of Semiconductor Processes and Devices, 2003.

We have analyzed high-dose low-energy B implants and theoretical structures with box-shaped B profiles that are fully active. These structures could be simplifications of the situation resulting from regrowth of preamorphized or laser annealed B implants. For these conditions, we have to take into account new effects due to the high B concentration and the proximity to the surface. The simulations show that the deactivation mechanism for B implants in crystalline Si takes place through a high interstitial content path, and it happens even for low B doses. The deactivation of the B box depends on the B concentration. In the absence of excess Si interstitials, B deactivation only happens for very high B concentrations. This process is very slow for low temperature anneals. If there is a residual concentration of Si interstitials along with the B box, the deactivation will take place rapidly even at low temperatures. In the model, the reactivation mechanism takes place in all cases through the low interstitial content path, by the capture of native Si interstitial defects and the emission of B interstitials.","PeriodicalId":220325,"journal":{"name":"International Conference on Simulation of Semiconductor Processes and Devices, 2003.

It is obvious that the quantum distribution of carriers will not fit to existing mobility models which were empirically developed employing a classical profile. Especially the terms which account for surface scattering need modifications. By utilizing an optimization framework and comparison with measurements stemming from overall 30 devices from two different technology nodes, this subject was rigorously investigated. Finally, a model was developed, where only one material parameter (instead of three) is needed to describe the semiconductor/oxide interface.","PeriodicalId":220325,"journal":{"name":"International Conference on Simulation of Semiconductor Processes and Devices, 2003.

Starting with a blanket silicon dioxide substrate and a patterned mask, we perform simulations of plasma etching, PVD barrier deposition, PVD seed layer deposition, electrochemical deposition of copper using an additive-containing bath, and chemical mechanical polishing. This virtual process sequence demonstrates the use of process simulation to study not just individual process steps, but process flows. After using 2d features and 3d/2d simulations to calibrate models for a particular process, we present samples of fully 3d/3d simulations to show possible approaches to answering questions that cannot be addressed by 2D simulators, such as deposition into dual Damascene structure and the plasma etching of porous materials.","PeriodicalId":220325,"journal":{"name":"International Conference on Simulation of Semiconductor Processes and Devices, 2003.
