COMSOL Day: Semiconductor Manufacturing
See what is possible with multiphysics modeling
COMSOL Day: Semiconductor Manufacturing is a one-day online event that will explore the use of physics-based simulation in the semiconductor processing industry. Multiphysics modeling plays an important role in the development of next-generation semiconductor products by helping researchers and engineers to achieve the high levels of model accuracy needed to keep up with advancements in technology. Throughout the day's sessions, various topics will be covered, including heat transfer, vacuum systems, semiconductor devices, and plasma reactors.
Plasma reactors are used in important surface-reaction processes in the fabrication of semiconductor devices. To understand and design plasma reactors, and predict their behavior, using modeling and simulation is key.
The Plasma Module, an add-on product to COMSOL Multiphysics®, provides a diverse set of features for modeling various types of reactors, including ICP, CCP, ICP/CCP, DC, and microwave-excited reactors. These features enable the modeling of fluid mechanics, reaction engineering, physical kinetics, heat transfer, mass transfer, and electromagnetics in 1D, 2D, and 3D for both time-dependent and stationary models.
Join us in this session to learn about the unique capabilities of the Plasma Module and see how they can be applied to plasma reactor modeling.
Thermal treatment and heat transfer are common processes involved in semiconductor processing. Physical modeling is used to better understand the impact of temperature changes and gradients in fragile semiconductor devices. Using modeling and simulation can help with decision making in design, optimization, and product quality control.
The COMSOL Multiphysics® software is widely used for modeling thermal stresses and strains to predict a device's failure susceptibility. It boasts a broad range of heat transfer modeling capabilities, including thermal contact, natural and forced convection, thermal radiation, and heat transfer in layered materials. It also offers unique functionality for modeling various heating mechanisms together with thermal stresses, such as Joule heating and other types of electromagnetic heating.
In this session, we invite you to learn more about the capabilities of COMSOL Multiphysics® for modeling thermal stresses and strains in semiconductor processing. You will see demonstrations of defining thermal expansion input parameters and temperature-dependent nonlinear materials.

The manufacturing of a semiconductor device can require more than 300 process steps: lithography, etching, deposition, implant, cleans, etc. Wet cleans and other liquid phase etches account for approximately 25% of all processing steps and are extremely important because failure to remove particles of just a few nanometers can cause devices to fail. This keynote talk will explain the basics of the different wet applications used in semiconductor manufacturing and then show how these are fundamentally multiscale processes, where macroscale conditions can affect device performance on the nanoscale. The talk will then give several examples and test cases where the use of simulations was crucial in being able to understand the underlying physics and work toward a solution.
Tech Lunches are informal sessions where you can interact with COMSOL staff and other attendees. You will be able to discuss any modeling-related topic that you like and have the opportunity to ask COMSOL technology product managers and applications engineers your questions. Join us!
When designing mass spectrometers, electron guns, and particle accelerators, particle tracing simulation is vital for accurately predicting the motion of ions or electrons in electric or magnetic fields. Depending on which kind of particles you are modeling, in the Particle Tracing Module, you can choose from a variety of built-in forces that affect their motion, including electric, magnetic, gravitational, and collisional forces. The Particle Tracing Module contains predefined expressions for the possible forces and interactions. It also enables bidirectional couplings between fields and particles for cases where particles impact the electromagnetic fields.
