SEMI New Activity Report Forms (SNARFs)
& SEMI Task Force Organization Forms (TFOFs)

Below you will find the TFOFs of all the task forces actively working in each region. The TFOF contains the charter and purpose of each task force.

The SNARFs that are listed under each task force are the individual activities of the task force. While the majority of these activities lead to the creation or revision of a standard, there are some activities which are focused on exploring and expanding the program.

If you have any further questions on a specific activity, contact your local Standards staff. A listing of global SEMI Standards staff can be found on the contact information page.
