Low-temperature Behavior in Nanowire Transistors by Quantum Transport Simulation

Abstract:

Quantum effects dominate at the nanoscale, where classical simulation tools lack the capability to accurately capture or observe these phenomena. Ciena’s analog design process relies significantly on provided models; however, as we scale, these models become increasingly less accurate. Consequently, we have initiated analysis and verification efforts to develop our own models to account for quantum effects. Additionally, we are required to analyze device behavior at cryogenic temperatures used in qubit technology.

Quantum device modeling requires specialized tools that can solve the Poisson-Schrödinger equations self-consistently. Silvaco’s Victory Atomistic tool easily met our initial requirements, but we quickly identified additional complexities, which prompted a close collaboration between Silvaco and Ciena teams to refine and enhance the tool.

Through this collaboration, we have developed an engine that closely simulates our in-house devices. Despite limited information about the fabrication process, we worked diligently to design a device model that approximates Ciena’s actual devices. While the model does not replicate measurements exactly, the trend of Victory Atomistic’s simulation graphs aligns well with the lab data for our 5nm devices at room temperature.

In advancing our qubit technology research, we successfully measured and observed device behavior at extremely low temperatures; however, the process was both costly and complex. To streamline our approach, we are working to replace physical measurements with device simulations, and Silvaco’s ViA shows promising potential in this area. At these extreme low temperatures, the tool initially faced numerical convergence issues, but with iterative improvements, these challenges are gradually being resolved. Future work will focus on further enhancing ViA, particularly to achieve stable convergence at lower cryogenic temperatures and lower bias conditions.

Machine Learning for Multi-Scale Plasma Process Integration and Optimization

Abstract:

This talk will explore advancements in plasma etching process optimization for process technology computer-aided design (TCAD), focusing on the integration of multi-scale modeling with AI-driven techniques. Key topics will include the development of equipment-informed feature-scale models, utilizing machine learning (ML) to bridge the gap between reactor and feature scales in plasma chambers. This approach supports predictive modeling for high-aspect-ratio (HAR) structures, critical for complementary metal-oxide-semiconductor (CMOS) applications and emerging device architectures.

A primary challenge in optimizing plasma etching processes is synchronizing the complex plasma chamber conditions across scales. We will discuss recent progress in creating surrogate models using equipment simulations such as the Hybrid Plasma Equipment Model (HPEM). Machine learning-based surrogate models, combined with available experimental data, can assist in an efficient generation of flux predictions. These models facilitate rapid feature-scale adjustments, fostering a digital twin environment with the potential for real-time optimization.

Ultimately, the proposed workflows have the potential to merge complex plasma chamber environments to TCAD, significantly reducing reliance on trial-and-error experimentation. This could lead to a more streamlined, efficient, and greener semiconductor manufacturing process.

Applying Artificial Intelligence in Fab Technology Co-Optimization

Abstract:

The common approach to optimize a fabrication process involves process and fab engineers creating and setting up Design of Experiments (DoEs) using a trial-and-error approach.

This approach often leads to costly iterations since wafer fabrication is both expensive and time-consuming. Typically, it can take weeks to months of experimentation, depending on what process parameters are not meeting their targets.

A new approach already in production use today leverages artificial intelligence (AI) and machine learning (ML) to generate an accurate simplified model of a fabrication step.

Silvaco’s FTCO Platform incorporates Machine Learning to accelerate semiconductor Digital Twin development. With Silvaco’s platform you can input your fabrication data and TCAD data to start building out an ML model.

Using Viso to Investigate, Analyze and Solve Advanced Parasitics Issues

Abstract:

In advanced technology nodes the impacts of parasitics in a design can be severe. Using simulations to identify and investigate such impact can be long and laborious. Viso is capable of tackling these issues and speed-up parasitics analysis. Viso is an advanced parasitics analysis solution to quickly analyze RC parasitic networks. Viso handles advanced nodes effortlessly, and its intuitive user interface allows to easily highlight and identify parasitics issues in the design. Viso features multiple analysis to obtain accurate information of the parasitics network, like timing estimations, crosstalk effects and matching between different nets. Such results can then be used to pinpoint troublesome areas in the design.

Here we will demonstrate how Viso can be used to investigate RC parasitic issues in high-speed circuits without the need of multiple iterations of long simulations.
