Webinar: Learn How to Use Victory Process TCAD Geometric Etch Models in FinFET and Memory Applications

May 18, 2023 @ 10:00 AM - 10:30 AM

May 18 Webinar

When: May 18, 2023
Where: Online
Time: 10:00am-10:30am-(PDT)
Language: English

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 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).
