Learning MEMS Design, Simulation and Fabrication Through 3-D Printing

Dahle R., Rasel R., SUNY New Paltz, US

This paper presents a cost-effective learning tool for modeling and simulating the microfabrication process and design aspects of MEMS devices using three-dimensional (3-D) printing. This approach was developed to provide engineering educators a more affordable [...]

A New Analytical Model of Channel Hot Electron (CHE) and CHannel Initiated Secondary ELectron (CHISEL) Current Suitable for Compact Modeling

Larcher L., Pavan P., Università di Modena e Reggio Emilia, IT

This paper presents for the first time a new approach to hot-carrier phenomena leading to an analytical model of both Channel Hot Electron (CHE) and CHannel Initiated Secondary ELectron (CHISEL) currents. This model can be [...]

Efficient Poisson Equation Solvers for Large Scale 3D Simulations

Speyer G., Vasileska D., Goodnick S.M., Arizona State University, US

Self-consistent semiconductor device modeling requires repeated solution of the 2D or 3D Poisson equation that describes the potential profile of the device for a given charge distribution. As a result, efficient methods for the solution [...]

Two-Dimensional MOSFET Dopant Profile by Inverse Modeling via Source/Drain-to-Substrate Capacitance Measurement

Chiang C.Y.T., Yeow Y.T., Ghodsi R., University of Queensland, AU

This paper proposes and demonstrates a new approach to 2-dimensional dopant profile extraction for MOSFET's by treating the source/drain-to-substrate junction as a gated diode. The small-signal capacitance of the diode measured as a function of [...]

Three-Dimensional Multi-Grid Poisson Solver for Modeling Semiconductor Devices

Wigger S.J., Saraniti M., Goodnick S.M., Arizona State University, US

In this paper, a full three-dimensional (3D), inhomogenous linear multi-grid Poisson solver is presented for application in particle-based simulation tools for devic emodeling. This algorithm represents the first such fully 3D multi-grid solver for device [...]
