Revised (if Applicable):
New Standard: Guide for Triethylgallium for HB-LED Manufacturing

Originating TC Chapter:
Task Force (TF) in which work is to be carried out:
HB-LED Source Materials TF
Note: If a new task force is needed, also submit a task force organization form (TFOF)
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.)
Unwanted impurities in metal organic sources, such as TEGa, may cause material defects and poor crystal qualities, resulting in poor performing LED devices. By establishing guides for the impurities in these metal organic sources, LED producers will be given proper operation guidance, which will enable production of HB-LED epitaxial processes.
b. Estimate effect on industry.
3: Major effect on a few companies - identify the relevant companies
Sector or Company Information:
c. Estimate technical difficulty of the activity.
II: Some Difficulty - Disagreements on known requirements exist but developing consensus is possible
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:
The properties of a source containing TEGa will be defined and target values provided including major and minor impurity concentrations.
b: Expected result of activity
New Standard or Safety Guideline (including replacement of an existing Standard or Safety Guideline)
For a new Subordinate Standard, identify the Primary Standard here:
For Standards, identify the Standard Subtype below:

6. Intellectual Property Considerations:
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 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:
