The Semiconductor Module and COMSOL Multiphysics® provide capabilities for modeling and optimizing semiconductor devices. This module relies on finite element and finite volume methods to solve the semiconductor equations for carrier concentrations and voltage distributions. From these, electric fields and transport properties, such as current and mobility, can be determined.
The Semiconductor Module makes it easy to couple lumped circuits to models of physical devices and to model phenomena such as electrostatics, heat transfer in non-isothermal devices, doping, and generation and recombination processes. Boundary conditions are easily implemented for modeling electric potential, terminals, ground, Ohmic and Schottky contacts, insulating regions, and surface charge accumulation. Predefined mobility models are also available such as the Arora, Fletcher, and Power-law models. The flexibility of the simulation environment also allows users to define their own boundary conditions and mobility models.
This webinar will show the capabilities of this module for modeling these applications, as well as methods available for importing geometry and interfacing COMSOL with other software programs. A live demonstration will be shown using COMSOL to model the DC characteristics of a MOSFET. The MOSFET model computes the threshold gate voltage at which current flows between the source and drain. The source-to-drain current-voltage characteristics are modeled for a range of gate voltages above the threshold, revealing the saturation and linear regions typical of transistor devices. The webinar will also include a Q&A session.
