New Standard: Specification for Centralized User Authentication and Role Authorization Management (CUARAM)
Originating Global Technical Committee:

Task Force (TF) in which work is to be carried out:
GEM 300 Task Force
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.)
Increasing process steps due to the complexity of semiconductor process require so many equipment groups to support required process steps.
In addition, increasing production volume of semiconductor factory for cost reduction requires so many same (or similar) equipment in each equipment group used in parallel in order to achieve required throughput of the factory.
On the other hand, security and safety managements of equipment have been becoming so crucial.
This results with a lot of work to manage required number of human users on such a big number of equipment.
- Registration, Role setting, Qualification setting, etc.
To reduce this work load, “Centralized User Authentication and Role Authorization Management scheme” is expected to be standardized.
Note 1: As described in 5.1.5, SEMI E132 refers only to the authentication of application processes, and does not support or address authentication of human users.
Note 2: This SNARF is raised based on the observations and assumptions from equipment supplier.
As there is no other formal place or way to ask necessity for the industry, this SNARF is proposed to see device manufacturers’ opinions first.
b. Estimate effect on industry.
2: Major effect on an industry sector - identify the relevant sector
Sector or Company Information:
User management of Semiconductor Industry
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:
This document covers following functions which support Centralized User Authentication and Role Authorization Management.
- User management
--- such as registration of Username, Password, Roles, Qualifications, and other required user information
- User authentication service
--- such as authentication service of a user upon a request from equipment
- Role management (Security (user role in organization) aspect)
--- such as definition of user Roles in the factory, registration and service of equipment type specific Role definitions
- Qualification management (Safety (user ability in technical work) aspect)
--- such as definition of user Qualifications (handling licenses such as toxic gas, liquefied nitrogen, vacuum subsystem, etc.) in the factory, registration and service of equipment type specific user Qualification definitions
- Equipment Mode definition
--- such as Production or Maintenance to be used for modification of permission per Equipment Mode
- Permission management
--- such as registration and service of equipment specific Role-Permission Descriptor per equipment type
- Access log service
--- such as a log with login in/out date, time, and equipment
- Other related functions which support above functionalities

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

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:
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:
