Training Course: Semiconductor and Molecular Flow Modeling in COMSOL Multiphysics^® (Paid)

If you are a new or experienced user of COMSOL Multiphysics^® who wants to learn how to use the software to model semiconductor and molecular flow applications, this is the online training course for you. During this course, you will develop a strong foundation for your future multiphysics modeling work. We will begin at an introductory level, leading you through the essential steps needed in all analyses (i.e., geometry creation, meshing, model setup, etc.).

We will use a combination of practical lectures, instructor-led hands-on training, and self-guided hands-on exercises to teach this course. The goal is to immerse you in all of the main aspects of using COMSOL Multiphysics^® and the add-on modules for semiconductor and molecular flow modeling so that you feel comfortable working with the software.

This course will run from April 22–29 and will include a final Q&A session on Tuesday, April 30.

Schedule

Day 1

Session 1: Introduction to COMSOL Multiphysics^®, Geometry, and Meshing

2:30–5 p.m. IST

In this session, we will introduce and showcase the capabilities of COMSOL Multiphysics^®. We will familiarize you with the UI and modeling workflow of the software and then introduce you to the different tools available in COMSOL Multiphysics^®, including various meshing features. We will cover geometry import and cleaning as well as advanced geometric operations, such as working with parametric geometry features. After this session, you will be able to create 3D geometries.

Next, we will cover structured and unstructured meshing and special meshing techniques, including boundary layer meshing, mesh convergence studies, automatic remeshing, and time-dependent remeshing. After this session, you will be comfortable in formulating a basic problem in COMSOL Multiphysics^®.

In the hands-on exercise, we will set up a multiphysics electric fuse model and analyze the working condition of the electrical fuse. At the end of the session you will be able to answer:

• What is the optimal thickness of the electrical fuse?
• Which material is suitable for the given specifications?

Day 2

Q&A for Session 1

2–2:30 p.m. IST

Session 2: Introduction to the Semiconductor Module

2:30–5 p.m. IST

This session will train users on the capabilities in the COMSOL^® software for modeling semiconductor devices. We will provide a brief introduction to how the Semiconductor Module can be used to analyze semiconductor device operation at the fundamental physics level. The discussion will focus on:

• Drift-diffusion equations
• The Schrödinger equation
• The Schrödinger–Poisson equation
• Material models and doping
• Metal–semiconductor contacts
• Insulator–semiconductor contacts

In the hands-on exercise, we will construct a simple 1D model of a metal–oxide–semiconductor (MOS) capacitor (MOSCAP). The MOS structure is the fundamental building block for many silicon planar devices. Its capacitance measurements provide a wealth of insight into the working principles of such devices. In this tutorial model exercise, we will compute both the low- and high-frequency capacitance-vs.-voltage (C–V) curves using the transient study approach. We will also compute the differential capacitance via two alternative methods: using the gate terminal and the metal contact terminal.

Day 3

Q&A for Session 2

2–2:30 p.m. IST

Session 3: Multiphysics of Semiconductor Devices

2:30–5 p.m. IST

Coupled physical effects often play important roles in semiconductor device performance. By combining different physics — such as electrostatics, heat transfer, wave optics, ray optics, and chemical species transport — multiphysics simulations can capture the complex interactions that occur within semiconductor devices. The key points of this discussion will cover:

• Modeling of thermal effects within a power device
• Illumination of silicon solar cells by modeling the solar rays
• Modeling stimulated and spontaneous emission by accounting for wave optics
• Coupling of a semiconductor and electrolyte model using species transport

In the hands-on exercise, we will perform a thermal analysis on a bipolar transistor model operated in the active-forward configuration. The tutorial model will demonstrate how to couple the Semiconductor interface with the Heat Transfer in Solids interface.

Day 4

Q&A for Session 3

2–2:30 p.m. IST

Session 4: Introduction to the Molecular Flow Module

2:30–5 p.m. IST

In this session, we will introduce the Molecular Flow Module, which can be used to model molecular flow for the design of vacuum systems and low-pressure gas flow at high Knudsen numbers. We will discuss the following topics:

• Free molecular flow
• Transitional flow
• Various boundary conditions

In the hands-on exercise (a benchmark problem), we will build a model to compute the transmission probability for molecular flow down a capillary tube of variable length.

Day 5

Q&A for Session 4

2–2:30 p.m. IST

Session 5: Multiphysics Applications Involving Molecular Flow

2:30–5 p.m. IST

This session will begin with an overview of the multiphysics modeling capabilities of the COMSOL^® software and explain how they can be applied to problems involving molecular flow. We will explain how to use the software's built-in multiphysics couplings, which combine multiple physics in a single physics interface. We will also discuss:

• Molecular behavior in the electric field
• Coupling of molecular flow and particle tracing

In the hands-on exercise, we build a model to compute the transmission probability of molecular flow through an S-bend geometry using both an angular coefficient method and a Monte Carlo method.
