Learn How to Efficiently Achieve Accurate Experimental Etch Profiles in FinFET and Memory Applications with Victory Process

August 11, 2022 @ 10:00 am - 10:30 am PDT

Silvaco, August 11, 2022

When employing process simulation to generate a complex device structure, TCAD engineers often face the task of reproducing the exact etch profile that has been observed in semiconductor fabrication. Silvaco Victory Process offers several geometric models to efficiently achieve etch geometries that accurately match microscopy images (e.g., transmission electron microscopy).

In this webinar, we present these geometric etch models in the context of FinFET and memory applications. We demonstrate techniques to realize fin shaping, non-ideal etch profiles (bowing, twisting), and self-aligned processes (multi-patterning).

What You Will Learn

  • How to achieve accurate etch profiles as observed on microscopy images
  • How to efficiently use Silvaco Victory Process to achieve fin shapes in FinFET flows
  • How apply geometric etch modes for trenches and contact holes in memory applications (3D NAND)
  • How to use Silvaco Victory Process’s powerful and adaptable ETCH DRY and ETCH POLYLINE commands
