This introductory demonstration will show you the fundamental workflow of the COMSOL Multiphysics® modeling environment. We will cover all of the key modeling steps, including geometry creation, setting up physics, meshing, solving, and postprocessing.
Etching of Silicon Nitride in 3D NAND Structures
As semiconductor devices continue to shrink in size, this continues to make new engineering challenges for companies operating in the industry. One important step in the manufacturing of memory devices is using phosphoric acid to etch silicon nitride (SiN) while not touching the surrounding silicon dioxide (SiO2). Derek will show his work in modeling and simulations that were used to better understand what process parameters are most important in controlling and improving this critical step.
Modeling and Design of Acoustic Metamaterials
What are acoustic metamaterials (AMMs) and why have they gained the attention of the scientific community in recent years? The original defining property of a metamaterial is that it achieves effects not found in nature as a means to address long-standing engineering challenges in acoustics. For example, can one create ultrathin acoustic barriers or absorbers whose performance surpasses currently existing technology? Is it possible to eliminate scattering from an acoustic sensor and minimize the influence the device has on the field being measured? Can spatially compact acoustical lenses be created whose resolution surpasses the diffraction limit? These are but a few examples of the problems AMM research strives to address. AMM research was originally motivated by parallel developments in electromagnetics, such as negative refraction and cloaking. Initial studies of these topics quickly uncovered that naturally occurring and existing man-made materials (composites) were not capable of providing the properties needed to create these devices. A straightforward reaction to this problem is to simply create new materials. Although not simple, the creation of new materials has been and continues to be the fundamental driving force for the study of AMMs. The challenge in developing new materials has been significantly aided by steady improvements in technology, primarily computer simulation and additive manufacturing. Those technologies combined with ingenious ideas from the acoustical research community have helped drive rapid advances in AMMs over the last decade, some of which will be addressed in this talk.

University of Texas at Austin Dr. Michael Haberman is an assistant professor in the Department of Mechanical Engineering at the University of Texas at Austin, with a joint appointment at their Applied Research Laboratories. He holds MSc and PhD degrees in mechanical engineering from the Georgia Institute of Technology and a PhD degree in engineering mechanics from the University of Lorraine in Metz, France. Dr. Haberman has worked extensively on the modeling and characterization of composite materials as well as the multiobjective design of acoustical materials. Currently, his focus is on the analysis, design, and testing of composite materials, metamaterials, and structures to absorb acoustical and vibrational energy using negative stiffness. He is also conducting research on passive and active materials that enable nonreciprocal wave phenomena in elastic and acoustic media.
Tokyo Electron Derek Bassett graduated from Brigham Young University with a BS in chemical engineering in 2004 and earned his PhD in chemical engineering from the University of Texas in 2010. Since then, he has worked at Tokyo Electron in the Advanced Technology Group. His work involves modeling, designing experiments, and performing simulations in order to improve and optimize semiconductor production tools. Mostly, he focuses on the spraying, coating, etching, and drying of wafers and using fluid dynamics to better understand and optimize those processes.
