Standards New Activity Report Form (SNARF)
Date Prepared: 04/07/2011Revised (if Applicable): 07/13/2011

Document Number: 5205
SNARF for: Revision to SEMI E154-1110, Mechanical Interface Specification for 450 mm Load Port

Originating Global Technical Committee: Physical Interfaces & Carriers
Originating TC Chapter: Japan
Task Force (TF) in which work is to be carried out: International 450 mm Physical Interfaces & Carriers
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.)
In 300mm, there are a lot of Indicator combinations because Indicator’s color and meaning of each color, size, number or layout is not standardized. .
Such variation of Hardware impacts on Load port operation software development and maintenance loads and lead time.
In order to facilitate rapid and cost effective transition for 450mm tool, a common specification with reduced variation for Load port Indicator is needed.

Proposed revision will not cover the Manual switch placement zone or switch itself. This direction is based on a belief that Indicator set hardware specification should be standardized with consideration of Auto/Manual mode software in 450mm.
Because 450mm is Auto mode keynote as ISMI 450mm/NGF “19 Points” Guideline #4 says “MHS Design to assume infrequent, anomaly manual handling only”.



b. Estimate effect on industry.
2: Major effect on an industry sector - identify the relevant sector
Sector or Company Information:

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:

Color, meaning of each color, number and layout for recommended set of Indicators
Indicator Placement zone
Indicator size


b: Expected result of activity
Revision to an existing Standard/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 14.1 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 or a copyrighted item(s) 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):


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:
will NOT include copyrighted material



NOTE FOR "the use of patented technology or a copyrighted item(s) is NOT required": If in the course of developing the document, it is determined that patented technology or copyrighted item(s) must be used to comply with the standard or safety guideline, the provisions of Section 15 of the Regulations must be followed.)

NOTE FOR "will include reproduced copyrighted material": A copyright release letter must be obtained from the copyright owner.
