SEMI International Standards
Standards New Activity Report Form (SNARF)
Date Prepared: 11/06/2018Revised (if Applicable): 11/05/2019

Document Number: 6489
SNARF for: New Standard: Guide for Reporting Chemical Mechanical Planarization (CMP) Polishing Pad Hardness used in Semiconductor Manufacturing

Originating Global Technical Committee: Liquid Chemicals
Originating TC Chapter: North America
Task Force (TF) in which work is to be carried out: Chemical Mechanical Planarization Consumables (CMP-C) Task Force
Note: If a new task force is needed, also submit a task force organization form (TFOF)

1. Rationale:
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.)

CMP polishing pad manufacturers rely on historical legacy metrology to measure polishing pad hardness which is not capable of accurately differentiating and correlating pad properties to CMP performance for current needs in semiconductor manufacturing.
A guide needs to be instituted to address these industry gaps.



b. Estimate effect on industry.
1: Major effect on entire industry or on multiple important industry sectors - identify the relevant sectors
Sector or Company Information: CMP polishing pads manufacturers and IDMs/fabs

c. Estimate technical difficulty of the activity.
II: Some Difficulty - Disagreements on known requirements exist but developing consensus is possible

___________________________________________________________________________
2. Scope:
a: 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:

• To determine and implement more capable metrologies to measure CMP polish pad hardness on any type of polish pads;
• To take into account temperature effect as it pertains to CMP polish pad hardness;
• To provide guidance for comprehensive reporting matrix parameters and test conditions.


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:

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

NOTE FOR "to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is NOT technically sound and complete - Refer to Section 15.1 of the Regulations for special procedures to be followed.

NOTE FOR "NOT to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is still technically sound and complete.

6. Intellectual Property Considerations:
a. 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:


b. For Revision, Reapproval, Reinstatement, or Withdrawal of existing Standard(s) and Safety Guideline(s):


c. The body of the Document and any Appendices, Complementary Files, Related Information sections, or Various Materials that may or may not be a part of the Document by reference:



NOTE FORthe use of patented technology or the incorporation of Copyrighted Item(s) is NOT required’: If in the course of developing the Document, it is determined that the use of patented technology or Copyrighted Item(s) is necessary for the Document, the provisions of Regulations 16 must be followed.

NOTE FORwill incorporate Copyrighted Item’: A copyright release letter must be obtained from the copyright owner prior to publication.
