SEMI International Standards
SEMI New Activity Report Form (SNARF)



Activity Number: 5524
SNARF for: Line item revisions to SEMI E156-0710, Mechanical Specification for 450 mm AMHS Stocker to Transport Interface


Originating Global Technical Committee: Physical Interfaces & Carriers
Originating Technical Committee Region: North America
Task Force in which work is to be carried out: International 450 mm Physical Interfaces & Carriers


1. Rationale: Key definitions for the 450 mm standards are not aligned with one another.
Rate the Estimated Effect on the Industry
4: Slight effect or effect not determinable

Rate the Estimated Technical Difficulty of the Activity
I: No Difficulty - Proven concepts and techniques exist or quick agreement anticipated

2. Scope:
a: Define the areas to be covered or addressed by this activity or document:
Revise SEMI E156 Acronyms to add KCP and Terminology to change KC pin to KCP. Revise the definition for facial plane to agree with that in the other 450mm standards. The location of the FP is not changed by this revision. These changes align SEMI E156 with SEMI E159 and SEMI M80.

b: Expected result of activity
Revision to an existing Standard/Guideline

3. Projected Timetable for Completion:
a: General Milestones
a. Activity Start: 10/01/2012b. 1st Draft by: 01/03/2013
c. Preballot by: d. Technical Ballot by: 01/03/2013
e. Committee Approval By:04/03/2013
