SEMI New Activity Report Form (SNARF)

Activity Number: 5438
SNARF for: New Standard: Test Method for the Measurement of Oxygen Concentration in PV Silicon Materials by Inert Gas Fusion Infrared Detection Method

Originating Global Technical Committee: Photovoltaic (PV) - Materials
Originating Technical Committee Region: North America
Task Force in which work is to be carried out: International PV Analytical Test Methods Task Force

1. Rationale: At the SEMI PV Int'l Analytical Test Methods Task Force Meeting during the Intersolar Tradeshow in Munich in June 2012 the need for a standardized test method for characterizing the oxygen content in silicon feedstock materials was discussed. A recommendation for such a standardized test method was made and backed by early results of a survey conducted by Peter Wagner.
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:
The scope of this activity is to draft, ballot and publish a standard test method for measuring the oxygen concentration in silicon feedstock for silicon solar cells by Inert Gas Fusion Infrared Detection.

b: Expected result of activity
New Standard

3. Projected Timetable for Completion:
a: General Milestones
a. Activity Start: 07/10/2012b. 1st Draft by: 07/10/2012
c. Preballot by: d. Technical Ballot by: 07/27/2012
e. Committee Approval By:11/01/2012

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: None.

Approval: Activity approved by Committee/GCS on July 11, 2012
