Accurate Parasitic RC Extraction using Realistic 3D TCAD Structures

Accurate determination of RC parasitics is a key component in the design and integration of many state of the art semiconductor technologies. Often, the traditional flow of using rule based parasitic extraction can fall short due to accuracy limits, or isn’t possible because the LPE rule decks are not available. To address this issue, physics-based parasitic extraction utilizing field solvers are an optimal solution. Field-based solutions are optimal as extraction can occur on realistic 3D geometries, accurately taking into account the more detailed geometric effects influencing RC parastics.

What attendees will learn:

  • Introduction to RC extraction – field solver vs rule-based approaches
  • Silvaco flow solutions from TCAD to SPICE
      Silvaco Victory Process 3D TCAD – layout driven 3D structure prototyping or detailed physical TCAD process simulation Silvaco Clever – physics-based resistance and capacitance field solver Silvaco SmartSpice – Accurate SPICE simulation solution
  • Applications
    • CMOS technologies including BEOL and MEOL parasitics
    • Display design
  • TCAD-to-Spice Flow
    • 3D Structure generation, accurate RC extraction and SPICE circuit simulation to include MEOL parastics for FINFET-based circuits


Dr. Garrett Schlenvogt is a Senior Applications Engineer within the Silvaco TCAD division, based out of Silvaco’s east coast sales/support office in North Chelmsford, Massachusetts.
