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

August 11 @ 10:00 AM - 10:30 AM

Alexander Toifl

When: August 11, 2022
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 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).
