Model Extraction Flow with Utmost IV for Vertically Stacked Nanosheets Using the Leti-NSP Model

Leti-NSP is an innovative model for advanced multi-gate MOSFETs. The model covers state-of-the art devices such as vertically stacked or vertical channel nanosheet/nanowires and FinFETs. In this webinar we will present a parameter extraction methodology for Vertically Stacked Nanosheets, based on this model. The extraction flow has been implemented in the Silvaco Utmost IV modeling software. We will illustrate the extraction flow step by step, emphasizing the particularities of its implementation in Utmost IV. Both the Verilog-A version of the model as well as the built-in model implementation in the Silvaco SmartSpice circuit simulator will be covered.

What attendees will learn:

  • Extraction of SPICE Model parameters for Vertically Stacked Nanosheets using the Leti-NSP model
  • Step-by-step illustration of the extraction flow implemented in Utmost IV
  • Comparison between the Verilog-A and the built-in version of the Leti-NSP model
