Tool Access, Roles & Process Development Policy

1. Purpose

This policy establishes one consistent process for how personnel gain authorization to operate tools in the Detector Microfabrication Facility (DMF), defines the roles involved in granting and maintaining that access, and describes how new fabrication processes and materials are introduced. It applies across the full DMF tool suite — lithography, deposition, etch, wet chemistry, and metrology tools — rather than being written per tool, so that every tool in the facility is governed by the same framework.

2. Scope

This policy applies to all staff, students, postdocs, and visiting researchers who wish to operate a DMF tool independently. It governs tool-specific access only, and does not replace or reduce DMF's general safety requirements. Completion of required ESH training and the DMF cleanroom induction (gowning, general safety, and emergency procedures) is a prerequisite to tool-specific training under this policy, not a substitute for it.

3. Roles

Four roles carry out this policy. A given person may hold more than one role — for example, a tool POC is very often also a Superuser on their own tool.
