    Coventor Adds Process Optimization Features to SEMulator3D® 8.0

    New Features Enable SEMulator3D 8.0 to Address Both Process Modeling and Device Analysis for Better Insight into Advanced Semiconductor Technology Development

    New in SEMulator3D 8.0, powerful new process simulation and analytics capabilities accelerate semiconductor technology development and Design-Technology Co-Optimization (DTCO).

    Fremont, CA—JULY 8, 2019 - Coventor, a Lam Research Company, the leading supplier of process modeling and simulation for semiconductor devices and micro-electromechanical systems (MEMS), today announced the availability of SEMulator3D 8.0 - the newest version of its semiconductor virtual fabrication platform. With added features, performance improvements, and a new Process Window Optimization capability, SEMulator3D 8.0 addresses both process and device simulation while lowering the barriers to advanced semiconductor technology development. The new Process Window Optimization (PWO) feature performs process window optimization without the requirement for time-consuming and expensive silicon wafer tests. This capability, in conjunction with existing SEMulator3D features, enables earlier understanding of critical process factors and their impact on yield.

    “With each release of SEMulator3D, we are providing more and more powerful analytics capabilities,” said David Fried, Vice President, Computational Products for Lam Research. “The new Process Window Optimization feature set, combined with our previously-released Analytics module, make SEMulator3D the most advanced solution for advanced process modeling. Our customers can now establish optimal process settings and process windows early in technology development and accelerate their time to market.”

    SEMulator3D 8.0 Productivity Enhancements

    The new version of SEMulator3D 8.0, which is available now, includes many additional features and performance enhancements such as:

    • Process Window Optimization

    The new Process Window Optimization workflow can be used to understand and identify the ranges of input parameters (i.e. the process window) needed to achieve user-defined performance goals and optimize product yield.  (more)

    • New Electrical Analysis Functionality

    A new ‘Validate Netlist’ feature is available to validate and merge extracted netlist files with reference CDL (circuit design language) netlists obtained from 3rd-party electronic design automation (EDA) tools. In addition, the resistance and capacitance solvers in Electrical Analysis are now substantially faster (up to 40X) compared to previous versions of SEMulator3D

    • Transistor Modeling Enhancements

    Small signal AC analysis is currently available, to accurately extract device capacitance and explore transistor process variability on device performance. A new variety of physical phenomena, such as field-dependent recombination and band-to-band tunneling, are now supported in the device solver.

    • Additional Process Modeling Features

    A new Monte Carlo implant step provides a more realistic ion implantation model, through advanced simulation of the ion implantation profile.

    • Custom Process Flows

    A new feature to import custom process flows and create SEMulator3D input files has been added, to support site-specific process flows

    SEMulator3D Version 8.0 will be installed and deployed at all major semiconductor customers in the US, Europe, Taiwan, Japan, Korea and China.

  • SEMulator3D
    A powerful 3D semiconductor and MEMS process modeling platform that offers wide ranging technology development capabilities....

  • By offering an unprecedented combination of speed, capacity and accuracy, SEMulator3D is uniquely capable of modeling complex integrated process flows across large silicon areas. Utilizing the SEMulator3D virtual fabrication platform, engineering teams can efficiently develop process flows and perform automated virtual experiments prior to actual fabrication.

    The SEMulator3D platform enables a new methodology for developing advanced semiconductor and MEMS processes. It is the fastest, most robust, and most accurate 3D semiconductor process modeling platform in the industry. SEMulator3D’s process-predictive capabilities benefit all participants in the semiconductor supply chain, from technology developers to fabless IP providers to equipment and process vendors.

    Benefits include:

    • Decrease costly, time-consuming silicon learning cycles

    • Identify process problems before fabrication

    • Perform variation experiments not feasible in the actual fab

    • Leverage virtual fabrication at every stage of technology development

    • Flexible platform for multiple use cases and applications

    • Applicable to any process and any layout, regardless of complexity or technology

    • Predicts complex interactions between designs and integrated process fows

    Challenges in current semiconductor processing extend beyond the single-device areas typically analyzed in the past. Traditional process modeling methods are limited to individual devices due to modeling performance limitations. SEMulator3D seamlessly switches between two sophisticated modeling methods: Voxel Modeling, a fast, robust, digital approach, and Surface Evolution, an analog approach capable of modeling a wide range of physical process behavior with great accuracy. This unique
    technology enables SEMulator3D to quickly solve today’s most advanced process problems.

    The World’s Top Semiconductor and MEMS Companies use the SEMulator3D platform for:

    • Process Exploration – Test processes not yet ready in the fab for integration impacts

    • Design Rule Validation – Check untested designs for yield-limiting process sensitivities

    • Process Margin Analysis – Identify process windows, and determine inline specications

    • Device Design – Export 3D models to FEA/BEA solvers for additional analysis

    • Wafer Characterization – Reduce metrology costs and accelerate silicon-based learning

    • Yield Optimization – Separate multi-process cross-wafer uniformity eects and optimize yield

    • Defect Analysis – Study and prioritize defect evolution modes through each process step

    • Documentation & Visualization – Create predictive 3D documentation for complex flows

    SEMulator3D oers much more than 3D visualization – it provides quantitative analyses of the complex 3D models it generates. Virtual Metrology, Structure Search, Design-Technology Checking, Prole Export, Expeditor, Electrical Analysis, Device Analysis, and Analytics each oers unique capabilities for measuring, checking and analyzing device structures for insightful quantitative results.
