It’s quite common to use focused laser light to rapidly heat materials for various purposes, including within the semiconductor processing industry. Here, we will look at a Gaussian profile laser beam with periodically pulsed intensity, heating up two different semitransparent materials deposited onto a silicon substrate. To model this, we will solve a multiphysics modeling problem using the temperature field and the Beer–Lambert law. Let’s further explore the model and see how to set it up… Read more
