The method is based on the self-consistent solution of the Poisson and Wigner equations within a device. The spherical harmonic approach is used to transform the Wigner equation into a tractable expression. The results provide the distribution function and its averages throughout the device. The method has been applied to a MOSFET and a BJT. Inclusion of quantum effects reduces carrier concentrations near potential energy barriers, leading to reduced terminal current.","PeriodicalId":132609,"journal":{"name":"2000 International Conference on Simulation Semiconductor Processes and Devices (Cat.

Measured current-voltage characteristics of advanced MOSFETs are thus reproduced with only 19 model parameters.","PeriodicalId":132609,"journal":{"name":"2000 International Conference on Simulation Semiconductor Processes and Devices (Cat.

In this work, the results of CMP simulation are shown to agree well with the measured data.

The new method, an exponential-fitting scheme, is evaluated using numerical examples involving both quantum confinement and tunneling.

In the simulation, an empirical tight-binding theory has been used to take into account realistic band structures. Comparison has been made between the results of our multiband (MB) model and those of conventional two-band (2B) model. It is found that the current-voltage (I-V) characteristics of the Si ITD have considerably smaller peak current density than the 2B model, since our MB model reflects the nature of indirect gap structure.","PeriodicalId":132609,"journal":{"name":"2000 International Conference on Simulation Semiconductor Processes and Devices (Cat.
