Standards New Activity Report Form (SNARF)
Date Prepared: 07/09/2018Revised (if Applicable):

Document Number: 6450
SNARF for: New Standard - Specification for Single Device Traceability for the Supply Chain

Originating Global Technical Committee: Traceability
Originating TC Chapter: North America
Task Force (TF) in which work is to be carried out: Single Device Traceability Task Force
Note: If a new task force is needed, also submit a task force organization form (TFOF)

1. Rationale:
a. Describe the need or problem addressed by this activity.
(Indicate the customer, what benefits they will receive, and if possible, quantify the impact on the return on investment [ROI] if the Document is implemented.)

A unique Electronic Chip ID (ECID), also known as a device ID, in silicon devices has been implemented in individual die/designs for over two decades. This identifier has been traditionally used by the silicon designers and manufacturers to trace die through the silicon manufacturing flow to aid the enhancement of silicon fab yields. An additional benefit of this ID is to be able to trace individual die and packaged parts through their final application testing in the final product before shipping to a customer. The ID can also be used to trace parts that subsequently fail in the field.

The recent evolution of data analytics is now allowing, via the device ID, end to end data analysis of single dies’ performances from initial wafer test to the product level test and field performance. Analysis of a device’s data in its native mode compared to its initial wafer or package (final test) testing data, now allows further in-depth yield learning. Silicon device fail data from failing die during the product manufacturing test (that forms the device’s DPPM [defective parts per million]), can be correlated back to the wafer and final test manufacturing test data to find new issues (e.g., silicon test coverage gaps and systematic and random defects found only during product level or system level test). Adding device ID to a component provides an extended opportunity to improve product quality and reduce DPPMs. Further, if a field recall is needed, individual faulty parts can be traced, thus greatly reducing the size of a recall, where all parts may have to be recalled if no device ID were present.

Device designers, manufacturers and suppliers that do not implement device IDs in their devices will be missing out on this opportunity to reduce DPPM. Many applications, like networking, medical and automotive are requiring the lowest possible DPPMs (trending to zero). Device ID for end to end traceability is one way to enable this continued quest for highest quality.

The resulting activity will establish a standardized approach for enabling traceable device-level identification (ID) throughout the IC manufacturing, test, and assembly processes to the point of use in the final system. Suppliers and board-level manufacturers can use this unique identifier to communicate about a specific device for the purposes of performance or failure analysis. The unique identifier will enable the ability to send manufacturing data back and forward through the supply chain to perform data analysis.

b. Estimate effect on industry.
1: Major effect on entire industry or on multiple important industry sectors - identify the relevant sectors
Sector or Company Information: materials suppliers, device designers, device makers, board manufacturers, and system integrators from various industry sectors such as semiconductor, automotive, and medical

c. Estimate technical difficulty of the activity.
II: Some Difficulty - Disagreements on known requirements exist but developing consensus is possible

2. Scope:
a: Describe the technical areas to be covered or addressed by this Document development activity. For Subordinate Standards, list common concepts or criteria that the Subordinate Standard inherits from the Primary Standard, as well as differences from the Primary Standard:

The resulting Document will establish a model focusing on the minimum of key concepts, behaviors, and requirements for enabling device ID and traceability. The standard is intended for implementation by materials suppliers, device designers, device makers, board manufacturers, and system integrators from various industry sectors such as semiconductor, automotive, and medical. This standard applies to different device configurations ranging from single integrated circuits to multi-chip/3D structures. This standard can be adapted for use with a range of technologies, ranging from legacy systems to the latest in electronic chip identification (ECID) and 2D code package marking. This standard defines, at a high level, the minimum requirements for device ID and traceability for new design and manufacturing implementation as well as for backwards compatibility with existing methods.

b: Expected result of activity
New Standard or Safety Guideline (including replacement of an existing Standard or Safety Guideline)

5. Safety Considerations:
The resulting document is expected:
NOT to be a Safety Guideline

NOTE FOR "to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is NOT technically sound and complete - Refer to Section 15.1 of the Regulations for special procedures to be followed.

NOTE FOR "NOT to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is still technically sound and complete.

6. Intellectual Property Considerations:
a. For a new Standard or Safety Guideline and for any part to be modified or added in a Revision of published Standards and Safety Guidelines:
the use of patented technology is NOT required.

If "patented technology is intended to be included in the proposed Standard(s) or Safety Guideline(s) " is selected above, then also check one:
