NFF Orientation

Would-be NFF users must first attend a series of trainings including Part A) Safety training, Part C) Contamination Control and Protocol , and Part D) NFF Website/Booking System training. The training course is held by NFF once a month with a maximum number of 12 applicants in one class. Part B) Chemical Safety – it is divided into two modules, Chemical Safety I (MC07) & II (MC03), and is delivered as a self-learning program by HSEO.

The aim of the training course is to introduce users to the cleanroom environment and to raise their awareness of work-related safety issues, to get familiar with the NFF website and booking system as well as to educate trainees on contamination issues and daily operation in the laboratory.

Admission Examination & Chemical Safety Training Assessment

Once an applicant has completed the training course, he must sit the admission examination and also the chemical safety assessment if he wishes to work in NFF laboratories

The examination consists of three papers:

  • Paper I - Safety
  • Paper II - Contamination Control and Protocol
  • Paper III - Process Flow

In general, the examination is held after the training course. Those applicants who fail the examination can re-sit only after re-attending the course.

The syllabus of the examination is as follows:

Paper I Topics:

  1. Cleanroom Environment
  2. MSDS & Material Restriction
  3. Alarm System and Emergency Escape Route
  4. General Lab Safety
  5. Fire and Chemical Safety
  6. Equipment and Operation Safety

Paper II Topics:

  1. Contamination
  2. Process Verification Scheme
  3. General Process Requirements
  4. Operation Guidelines
  5. Cleanliness Levels of Equipment and Wafer Status

Paper III Topics:

  1. Paper II Topics
  2. Standard Format of Process Flows

Types of Users in NFF

There are three types of users in the NFF: Non-CMOS users, CMOS users and super users. Non-CMOS users are not allowed to use any CMOS equipment to run their Non-CMOS processes. CMOS users are allowed to use all CMOS equipment. Super users are allowed to use all CMOS equipment as well as to operate certain equipment after stipulated NFF operation hours.

The basic requirements for non-CMOS user who are qualified to apply non-CMOS projects are as follow:

  1. Attended parts A, B, C and D of the training course
  2. Passed the Admission Examination and the chemical safety assessment
  3. Get a process flow for approval for a non-CMOS project and then obtain a designed booking account and ID card

The basic requirements for CMOS user who are qualified to apply CMOS projects are as follow:

  1. Must have non-CMOS users qualification mentioned above
  2. Passed ELEC5080 course or equivalent
  3. Get a process flow for approval for a CMOS project and then obtain a designed booking account and ID card

The requirement for super user:

Special approval is needed for super user. Please contact NFF staff for details.

NFF User Application Form and Process Flow

Users must submit their process flow to the NFF before starting their processes. A process flow can help us gauge the feasibility of the process and effectively control the risk of wafer contamination. The link below shows a sample of a process flow.
