Standards New Activity Report Form (SNARF)
Date Prepared: 05/14/2020Revised (if Applicable): 07/13/2020

Document Number: 6682
SNARF for: Line Item Revision to E142-XXXX: Specification for Substrate Mapping, E142.1-1016 XML Schema for Substrate Mapping and E142.2-1016 SECS II Protocol for Substrate Mapping

Originating Global Technical Committee: Information & Control
Originating TC Chapter: North America
Task Force (TF) in which work is to be carried out: Advanced Backend Factory Integration
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.)
Adding package path to layout - E142 provides a framework to describe the hierarchical layout of complex electronic assemblies. In many cases, multiple packages are assembled on a substrate, e.g. a wafer or a strip, that is later singulated to yield the functional part to be sold or assembled into a larger package. It is helpful to know which layout paths in the hierarchy represent an individual functional package, for example to allow a fail bin for one die in a multi-chip package to cause the entire package to be marked with a fail bin. This line item will add an attribute to the layout object to identify it as a package or not

Review the data model, XML examples and schema – There are some inconsistencies between the data model and the schema and the XML examples belong in the sub-document E142.1 alongside the XML schema rather than in the parent E142 document related information sections.

Comply with the Style Manual - SEMI E142 uses words that contradict the latest version of the Style Manual. (for example, use the word ‘must’ rather than ‘shall’). Changes to align with the latest version of the Style Manual will be made

Extending data transfer methods – With the addition of DeviceData to E142 the map data size may become too large for the SECS II messages defined. An alternative method will be proposed to use Stream 21 SECS-II messages to transfer maps.

b. Estimate effect on industry.
2: Major effect on an industry sector - identify the relevant sector
Sector or Company Information: Packaging, Testing, Backend automation

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:
• To add package path to the layout. The schema in E142.1 and the XML examples in E142.2 will be updated to synchronize with the changes.
• Review and update E142 and E142.1 related information.
• SEMI E142 uses words that contradict the latest version of the Style Manual. (for example, use the word ‘must’ rather than ‘shall’). Changes to align with the latest version of the Style Manual will be made
• SEMI E5 supports Stream 21 messages to transfer data between the Host and Equipment. E142.2 will be updated to allow Stream 21 messages to transfer maps to and from the host. A new configuration switch will specify which mechanism (Stream 21 messages or S14F1/F2 and S6F11 messages) will be used to transfer maps.
• Make minor editorial changes and technical errors identified during the ballot creation

b: Expected result of activity
Line-item revision to an existing Standard or Safety Guideline

b. List any planned Type I Liaisons with external nonprofit organizations (e.g., SDO) that should receive Draft Documents from Standards staff for feedback during this activity and be notified when the Letter Ballot is issued (refer to Procedure Manual 7):

c. Intercommittee Ballots:
will not be issued

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:

b. For Revision, Reapproval, Reinstatement, or Withdrawal of existing Standard(s) and Safety Guideline(s):
there is no known material patented technology necessary to use or implement the Standard(s) and Safety Guideline(s)

c. The body of the Document and any Appendices, Complementary Files, Related Information sections, or Various Materials that may or may not be a part of the Document by reference:
the incorporation of Copyrighted Item will NOT be required

NOTE FORthe use of patented technology or the incorporation of Copyrighted Item(s) is NOT required’: If in the course of developing the Document, it is determined that the use of patented technology or Copyrighted Item(s) is necessary for the Document, the provisions of Regulations 16 must be followed.

NOTE FORwill incorporate Copyrighted Item’: A copyright release letter must be obtained from the copyright owner prior to publication.
