Modeling On-Currents for n-MOSFETs: Ultimate Limits vs. the NTRS

Assad F., Ren Z., Vasileska D., Datta S., Lundstrom M.S., Purdue University, US

The continued evolution of Si technology hinges to a large extent on the ability to maintain high on-currents while achieving low off-currents. As we move from sub-micron to nanoscale technology, it is not at all [...]

Complex Potentials, Dissipative Processes and General Quantum Transport

Ferry D.K., Barker J.R., Akis R., Arizona StateUniversity, US

Complex potentials have been used in the past to simulate dissipative processes, but the normal form of a simple constant term of the form t / h i serves only to trap/detrap particles and does [...]

Ab-Initio Pseudopotential Calculations of Boron Diffusion in Silicon

Windl W., Stumpf R., Masquelier M., Bunea M., Dunham S.T., Motorola, US

First-principle calculations of formation and migration energies of dopant atoms and native defects in semiconductors are a very useful input to improve semiconductor process simulations One example of this is the widely accepted first-principles model [...]

Ab-Initio TCAD Models of Dopant Diffusion in Silicon

Nelson J.S., Wright A.F., Schultz P.A., Sandia National Laboratory, US

The rapid pace of the silicon microelectronics industry, and its need for physics-based TCAD models of dopant diffusion, is coinciding with the tremendous algorithmic and computational advances occurring within modern ab initio electronic structure methods. [...]

Accurate Three-Dimensional Simulation of Damage Caused by Ion Implantation

Hössinger A., Selberherr S., TU Vienna, AT

We present a Monte-Carlo ion implantation simulation method that allows a very accurate prediction of implantation induced point defects, generation of amorphous areas, and impurity distributions. The implanted impurity profiles can be calculated as well [...]

Modeling and Simulation of Non-Linear Damage Growth During Ion Implants in Silicon

Son M-S., Hwang H-J., Chung-Ang University, KR

In this work, we presents a newly proposed and enhanced damage model for the accurate prediction of both as-implanted impurity and point defect profiles in Monte Carlo simulation of ion implantation in (100) crystalline silicon. [...]
