SEMI International Standards
SEMI New Activity Report Form (SNARF)



Activity Number: 5033
SNARF for: New Standard:Specification For Ammonia (Nh3) In Cylinders, Xx.Xxx% Quality, Used In Photovoltaic Applications


Originating Global Technical Committee: Photovoltaic
Originating Technical Committee Region: North America
Task Force in which work is to be carried out: PV Gases and Liquids Chemicals Purity Task Force


1. Rationale: The needs of PV end-users differ slightly from those in semiconductor when it comes to gases used during production. Our taskforce will take an existing SEMI document as a template and convert it into an ammonia standard for use in photovoltaic applications.

NOTE: Until the TaskForce researches the need, the % quality cannot be defined for this SNARF.
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:

Purity requirements of ammonia used in the manufacturing of photovoltaic cells.

b: Expected result of activity
New Standard

3. Projected Timetable for Completion:
a: General Milestones
a. Activity Start: 02/01/2010b. 1st Draft by: 06/01/2010
c. Preballot by: d. Technical Ballot by: 09/01/2010
e. Committee Approval By:01/01/2011

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: None.

Approval: Activity approved by Committee/GCS on July 14, 2010
