Tier 1: Microscopic TCAD & Poisson-Drift-Diffusion

Tier 1 provides microscopic device-level Technology Computer-Aided Design (TCAD) finite-difference mesh physics.

Physical Models

• 1D/2D Non-Uniform Finite Difference Mesh: Dynamic adaptive node distribution around junctions and dielectric interfaces.
• Non-Linear Poisson Equation: Fully resolved electrostatic potential profiles with Fermi-Dirac electron and hole distribution functions.
• Drift-Diffusion Current Continuity: Carrier drift under local electric fields coupled with spatial gradient diffusion.
• Band Bending & Short-Channel Effects: Drain-Induced Barrier Lowering (DIBL), velocity saturation, and surface mobility degradation.
