TechEdge™ Excursion Control

What it Does

TechEdge Excursion Control is a new technology-enabled advanced service offering that:

  • Reduces or eliminates process excursions that impact yield and unscheduled downtime.

  • Diagnoses and monitors process performance based on customer prioritization to identify operational shifts that correlate to undesirable process quality or device performance.

  • Uses a combination advanced sensor tracking technology and certified TechEdge engineers to deliver expanded process data reporting capability to customers.

  • Is delivered using E3 process data collection capability and analysis systems.

  • Includes an experienced team of process, tool, and FDC experts who:
    • Create specific FDC models and E3 strategies to diagnose, detect, and proactively respond to critical tool issues; when an issue arises, automated notification includes customer e-mail as well as optional lot/equipment holds to prevent product and process quality variation.

    • Provide problem description and tool/chamber and lot identification.

    • Perform necessary diagnostics and corrective actions to resolve issues.

    • Analyze issues and provide improvements through weekly and monthly meetings and strategic recommendations and economic impact in quarterly reviews.

TechEdge Excursion Control is a value-add option that complements existing service offerings by providing a more proactive “predict and prevent” approach. It can be sold as an option to customers with Applied Managed Service (AMS) or Applied Performance Service (APS) to help deliver additional tool performance that is not part of these standard service product entitlements. It uses the FDC model library and proprietary technology to increase predictive maintenance capability and add value to established contract commitments.
