Date Prepared: 11/06/2019Revised (if Applicable):

Document Number: 6592
SNARF for: New Standard: Specification for Container for Transport and Storage of Transmission Electron Microscope (TEM) Lamella Carriers within Electron Microscopy Workflows

Originating Global Technical Committee: Physical Interfaces & Carriers
Originating TC Chapter: North America
Task Force (TF) in which work is to be carried out: Electron Microscopy Workflow 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.)
The PIC TC Chapter recently approved SEMI E177-0919 specifying the lamella carriers (LCs) used in Transmission Electron Microscopy (TEM) investigations. This was a first step for enabling automated workflows for TEM investigations in a fab environment. For a fully automated workflow standardization of other steps and components is required. One logical next step is the standardization of a container for the LCs. The LCs need to be transported between the different tools in a fab or lab that are part of the TEM workflow (FIB-SEM, plasma cleaner, TEM, storage). For this a well-defined, standardized container is required - similarly to FOUPs used for transporting silicon wafers - so that the interfaces of the various tools used can be designed and which complies with existing automated transport systems. This container is intended only for transporting the LCs within a fab/lab as well as for long term storage and not for shipping the LCs from the LC manufacturers to the LC customers/end-users.


b. Estimate effect on industry.
2: Major effect on an industry sector - identify the relevant sector
Sector or Company Information: Suppliers and users of FIB, SEM, TEM, lamella carriers, cleaning and storage equipment.

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:
- The new standard will specify the form factor, parts and physical dimensions of the LC container.
- It will also specify the detailed design of the LC container such as the pockets/slots for the LCs and the fixture mechanism for the LCs.
- It will also specify physical features related to the storage, handling, transport and identification of the LC containers (e.g. fiducials for alignment, id location, etc.)
- In addition, the new standard will define new terms related to this activity.
To arrive at the new standard it will also be required to consider the possible mechanism(s) by which the LCs will be transported in and out of the container and how LC identification within the container will be realized (LC face-up/down; LC horizontal/vertical; vacuum end-effectors from top or bottom, ID read-out from top or bottom, etc.)


b: Expected result of activity

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:
the incorporation of Copyrighted Item will NOT be required



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.
