Abstract
The present work is dedicated to the study of warpage that takes place on direct bonded copper (DBC) substrates. The ultimate goal of the work at hand is to establish a universal standard for identifying and predicting warpage behavior in DBC substrates. To achieve this, the study aims to conduct simulations in parallel with experimental measurements on real-time and applicable components. The study's methodology is divided into three main stages: post-production, post-reflow, and post-operation of the DBC substrates. Within each stage, corresponding simulations have been performed in COMSOL Multiphysics in parallel with the experimental measurements, which were undertaken using the KLA Tencor P-17 Profiler.
The post-production stage is associated with the DBC substrates’ condition after the process of their production
