SEMI New Activity Report Form (SNARF)



Activity Number: 5010
SNARF for: Revision to SEMI PV4 Specification for Range of 5th Generation Substrate Sizes for Thin Film Photovoltaic Applications


Originating Global Technical Committee: Photovoltaic
Originating Technical Committee Region: Japan
Task Force in which work is to be carried out: Japan PV Materials Task Force


1. Rationale: SEMI PV04 was developed to reduce equipment (including AMHS) cost and to make wider opportunity of selection of equipment by giving a guideline on substrate size.
It was found during development and adjudication process of PV04 that further specification to the tolerance of substrate dimension would improve the effectiveness and usability of the Standard.
This activity will address the “tolerance issue” by revising PV04.
Rate the Estimated Effect on the Industry
2: Major effect on an industry sector - identify the relevant sector

Rate the Estimated Technical Difficulty of the Activity
II: Some Difficulty - Disagreements on known requirements exist but developing consensus is possible

2. Scope:
a: Define the areas to be covered or addressed by this activity or document:
This revision address further optimization of the tolerances for substrate dimensions.

This standard does not cover;
- Edge treatment
- Weight
- Material
- Orientation for transfer

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

3. Projected Timetable for Completion:
a: General Milestones
a. Activity Start: 07/02/2010b. 1st Draft by: 09/15/2010
c. Preballot by: d. Technical Ballot by: 09/15/2010
e. Committee Approval By:12/05/2010

b: Activity Specific Milestones
a. Proof of Concept b. Acquisition of Resources:
c. Safety Checklist Completed



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


Intellectual Property Considerations:
a. In complying with the standard or safety guideline to be developed, the use of patented technology or a copyrighted item(s) is NOT required
b. The body of the standard and any appendices or related information sections will NOT include copyrighted material

Comments, Special Circumstances: This activity was arisen from Negatives on the ballot to Doc.# 4799, which was published as PV-04.
This revision activity deemed necessary at the time of ballot adjudication.

Approval: Activity approved by Committee/GCS on July 2, 2010
