Modeling and Inverse Identification of Interfacial Heat Conduction in Finite Layer and Semi-Infinite Substrate Systems via a Physics-Guided Neural Framework

arXiv — cs.LGWednesday, December 3, 2025 at 5:00:00 AM
  • A new framework named HeatTransFormer has been introduced to model interfacial heat conduction in semiconductor devices, addressing the challenges posed by steep temperature gradients at the interface between a finite chip layer and a semi-infinite substrate. This physics-guided Transformer architecture aims to enhance the transient thermal response without the excessive discretization required by conventional numerical solvers.
  • The development of HeatTransFormer is significant as it promises to improve the accuracy and efficiency of thermal modeling in semiconductor devices, which are critical for the performance and reliability of modern electronics. By leveraging a physics-informed approach, it seeks to overcome the limitations of existing methods, particularly in terms of convergence and physical consistency.
  • This advancement reflects a broader trend in the application of Physics-Informed Neural Networks (PINNs) across various fields, including ecological modeling and engineering systems. The integration of PINNs in diverse applications highlights their potential to address complex dynamical systems, suggesting a growing recognition of their utility in enhancing predictive capabilities and optimizing processes in both engineering and scientific research.
