Agenda

Advanced packaging allows for fine-pitch interconnects to run between the multiple chips (or “chiplets”) composing a system-in-package (SiP). Within a SiP, the IO ports of the die-to-die (D2D) interfaces are minimally stressed during component-level CDM and HBM testing because they are not connected to the external balls or pins of the package. Nevertheless, it is unknown whether on-chip ESD protection can be eliminated from those pads due to the risk of static charge injection during assembly on advanced packaging. This workshop will include a review of what’s known about ESD current injection during assembly.

The workshop will begin with a quick overview of the advanced packaging roadmap and an exemplar of a D2D interface standard. Next, each of the panelists will discuss their experience characterizing and simulating the ESD that arises during chiplet assembly. This will be followed by an opportunity for the audience members to ask questions of the panelists and to share their own observations and recommendations. Finally, panelists and audience members alike will propose suitable test methods and target levels for the D2D IO, based on the current understanding of the ESD hazard.

As ICs evolve toward chiplet based systems with thousands of internal connections, traditional CDM qualification approaches no longer scale—or always make sense. This workshop shifts the discussion away from "how to test CDM" to "when and why CDM testing is needed". Using concrete examples such as internal chiplet pins versus high risk external SERDES I/O, we explore which interfaces warrant CDM protection and testing, which may not, and how to justify those decisions. The session addresses design time risk mitigation, alternatives to qualification testing, and how responsibility is shared across design, fabrication, assembly, test, and system integration when things go wrong. 

Modern high speed wireline interfaces are increasingly moving from board level links into packages and chiplet based systems, introducing new challenges for ESD engineers. Interfaces such as UCIe and advanced die to die PHYs differ fundamentally from traditional external I/O, yet their ESD implications are not well understood. This workshop is structured as a foundational course, aimed at closing this knowledge gap. A wireline interconnect expert will introduce modern chiplet PHY architectures and design constraints, followed by discussion on how these technologies challenge classical system level ESD assumptions and protection strategies. 

A person certified in process assessment will possess a foundational understanding of general process assessment strategies, specifically those covered during the training. However, this certification does not equip individuals to conduct assessments in every possible scenario. Practical, hands-on experience with real-world process assessments is essential and cannot be fully replaced by the training provided in this certification.

Who Should Consider This Certification:

• ESD Professionals and Process Engineers working in factory environments who are responsible for identifying and evaluating potential ESD risks.
•      Individuals seeking training that extends beyond the scope of process assessment as defined in ANSI/ESD S20.20 particularly those interested in hands-on experience, measurement techniques, and applying Process Assessment Evaluation (PAE) in real-world settings.
•      Those assigned to assess ESD risks within their organization and who require both the training and credentials necessary to perform effective process assessments.
•      Individuals with prior experience in process assessment wish to deepen their expertise and broaden their perspective with additional techniques and considerations.

Learning outcome/skill sets:

•  Develop a systematic approach to process assessment and troubleshooting, grounded in ANSI/ESD SP17.1 principles.
• Gain knowledge of advanced measurement techniques used in process assessment (PA).
• Understand key manufacturing processes, identify critical steps prone to ESD risk, and explore effective mitigation strategies.
• Acquire a foundational understanding of Electromagnetic Interference (EMI), Electrical Overstress (EOS), and relevant auditing methodologies.

Pre-requisites recommended (advanced topics):

• 3–5 years of experience in ESD
• Experience in basic ESD measurement techniques, for example, TR53 certification or equivalent knowledge

Classroom subjects

•            Motivation for process assessment
•       Introduction to physical parameters
•       ESD models of devices, systems, and boards and their relevance in the field

      The in-person format, which will include demonstrations, exercises, and hands-on opportunities for students, is as follows:

•      Determining the ESD robustness of devices and boards
•      ESD assessment flow I – manual handling   
•      ESD assessment flow II – isolated conductors

•      ESD risk assessment flows for troubleshooting
•      Examples of successful ESD risk assessment

  Exam    

•        Written (multiple choice) exam         
•        Hands-on exam (assess a typical process)   - one hour practical exam
