Training
Before submitting a training request, please review the prerequisites for each instrument listed below.
Starting in July 2026, a standardized training request form will be introduced. The new system will allow users to request training for multiple instruments using a single form (NBI-Cleanroom Training Request Form). Please only request training for instruments that require immediate access. Following submission of the request form, email communication will continue to be used for scheduling and coordinating training activities. The Cleanroom staff will acknowledge and respond to training requests within 1-2 working days.
Please note that access to the Cleanroom, tool laboratories and individual instruments can only be granted after the required safety instructions and instrument training have been completed and approved by the Cleanroom staff. Upon successful completion of the training, users will be granted booking privileges through Cleanroom Booking System.
To ensure continued competency and safe operation, booking privileges and laboratory access may expire after a period of inactivity (90 days) for a given instrument or Cleanroom usage. In such cases, users will be required to complete a refresher training session before access can be reinstated.
Cleanroom General (Safety) Introduction
Before attending the training session, all users must read and familiarize themselves with the relevant safety information (Safety). Expand to view more information.
- The introductory session is scheduled from 09:15 to 15:00.
- Training sessions are conducted in group of 3-4 participants. Once a training date has been proposed by the Cleanroom staff, participants are required to confirm their attendance by email (cleanroom@nbi.ku.dk).
- If fewer than 3 participants are available for a scheduled session, an alternative training date may be proposed. If a session reaches its maximum capacity of 4 participants, additional users will be placed on a waiting list and offered the next available training opportunity.
- Please identify a superuser from your research group who will serve as your mentor during your first few weeks of working in the Cleanroom.
- The designated mentor is responsible for guiding you through the standard procedures and best practices after the Cleanroom General Introduction.
- Once the mentor has determined that you are competent to work independently, they must notify the Cleanroom team via email.
- Full access to the Cleanroom laboratories will only be granted after the Cleanroom team has received this confirmation.
- Standard Training Program:
- 09:15-10:30: Cleanroom introduction
- Coffee break
- 10:45-12:00: Asher, spinners and optical microscopes
- Lunch break
- 13:00-14:00: Practical information
- 14:00-15:00: Q&A and account setup

- Elionix is a high level tool. Make sure you are already trained to:
- Enter the cleanroom
- Use the microscope, spinner, asher
Training
- You'll need 4 sessions to get trained on this tool.
- Session 1 ( 1 hr.) - teaches you how to load/unload the sample and how to condition the beam.
- Session 2 ( 3 hr.) - involves exposing alignment marks and test patterns (any design: preferably one half of the overlay ,so to understand alignment later ).
- Session 3 ( 3 hr.) - involves using the exposed alignment marks for marker registration and exposing the 2nd pattern (i.e. the 2nd half of the overlay pattern).
- Session 4 involves exposing a "real" pattern on a "real" chip on your own to gain access.
Preparation
Before any training slots are booked on the tool you'll need all of the following prepared:
- Shadow senior users on the tool 2-3 times.
- Chip (comfortable to handle) spin coated with resist. This chip will be used for sessions 1 & 2. Please be aware of the coating and baking parameters for the resist.
- Any test design is preferred which has marks, overlay patterns that you will use to test alignment precision between two lithography steps. A Vernier pattern is commonly used. Feel free to test your ideas. Make sure you have something for both x and y directions. If you don't know how to start, check the Design template for EBL.
- Convert your design files into the Elionix exposure format .co7. This can be done using Beamer in 4th floor design computers.
- Make sure all write fields are entirely in the positive coordinate space.
- Make sure neither exposure will take longer than 60 minutes at 500 pA current and dose of 1000 uC/cm2.
