PCGD: Physics-Guided Conditional Graph Diffusion for TCAD Device Simulation

Yihan Zhang, Zhiteng Zhang, Kun Chen, Chen Wang

Technology computer-aided design (TCAD) semiconductor device simulation is fundamentally constrained by the high computational cost of iteratively solving coupled drift-diffusion equations. Existing ML surrogates either reduce internal physics to macroscopic scalar regressions, o…Read more
