Standards New Activity Report Form (SNARF)
Date Prepared: 04/15/2010Revised (if Applicable):

Document Number: 4980
SNARF for: Revision to SEMI E154-0310, Mechanical Interface Specification for 450mm Load Port

Originating Global Technical Committee: Physical Interfaces & Carriers
Originating TC Chapter: North America
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.)
The 450mm Load Port standard was published by SEMI as E154 in February 2010 for 450 FOUP, but it did not comprehend the Shipping Box Carrier due to carrier design not being ready/finalized. Now the 450 NA Shipping Box TF has closed the design for the 450mm Multi Application Carrier (MAC) and the 450 International Shipping Box TF has close on the architecture design and is in the process of closing the remaining design parameters, the TF needs to get the load port document updated. Both 450 MAC and 450 FOSB will have a yellow ballot for Cycle 4, 2010.

So we need to update the Load Port standard to comprehend the MAC and FOSB standard based on agreement between the TFs. These changes will be balloted as a line item(s). This ballot needs to be submitted for Cycle 4, 2010 as well.

Load Port Yellow Ballot submission was approved the NA PIC Committee in the March 2010 SEMI Spring Meeting.

b. Estimate effect on industry.
4: Slight effect or effect not determinable
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:
1. Comprehend 450 MAC and 450 FOSB maximum door thickness y58< 52.25mm dimension related changes in the 450 Load Port Standard (E154)

2. Comprehend 450 MAC door closing force related changes in the 450 Load Port Standard (E154)

3. Comprehend 450 FOSB door closing force related changes in the 450 Load Port Standard (E154)
a. Note: If the FOSB closing force related changes cannot be accommodated/comprehended, TF should propose an approach to the NA PIC/GCS Committee on how to proceed, e.g. separate load port document(s) ASAP – i.e. no later than one week (five business days) prior to May 17th Cycle 4 deadline.

b: Expected result of activity

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 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 16 of the Regulations must be followed.)

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

7. Comments, Special Circumstances:
Intellectual Property Considerations:
Patent and/or patent applications material to this Standards draft document is unknown. Once the task force has determined that there is no alternative to the use of patented technology or copyrighted item(s), this SNARF will be revised then reapproved by the committee and the Global Coordinating Subcommittee (GCS).

8. TC Member Review:

Member Review Start Date; None.
Member Review End Date: None.

NOTE FOR ‘TC Member Review’ is required by the Regulations for a period of at least two weeks
before approval of a new, or a major revision of an existing, Standard or Safety Guideline. (See Regulations 8.2.1)
