NEW Job ID: J-00276502-797


Are you studying Mechanical Engineering or Mechatronics? Do you have experience with statistical analysis? Then this internship could be interesting for you!

Background information

The DUV Mechanical System Layout group delivers the high-level mechanical system layout that enables the optimal functionality and cost-effective engineering of complete DUV lithography systems and its build, transport and install requirements.

We are continuously improving our mechanical layout in terms of performance, quality, manufacturability and serviceability, whilst delivering towards our customer demands.

Your assignment

Main task:

Perform a Tolerance Analysis on Illuminator Position & Service Module, taking into consideration its impacts on mechanical adjustment procedures and machine functional requirements.
The focus of this investigation is to look for tolerance relaxation opportunities on applicable tolerance chains and find the sweet spot between performance (mechanical accuracy) and manufacturing costs reduction.

This task includes:

- Tolerance Stack-Up calculations.
- Statistical analysis
- Mechanical drawing interpretation
- Cross team collaboration
- Provide recommendations

Your challenge will be to present how is the current status of this tolerance chain and how much tolerance can be relaxed on Illuminator Position & Service Module without compromising functional requirements. Besides that, considering improvements on an existing design, using drawings and adjustment procedures as input and collaborating with Mechanical Constructions, Mechanical System Layout, and Imaging Architecture to achieve results and make solid conclusions and recommendations.

Your profile

To be the perfect match for this internship you:

  • Are studying Mechanical Engineering, Mechatronics or a related field;
  • Have experience with statistical analysis;
  • Have knowledge on Mechanical Drawing Interpretation, Tolerance stack-up calculation and Mechanical design;
  • Have knowledge in CAD and Excel;
  • Are eager to look for the information and the data needed to perform the analysis (by asking module experts, reading specification documents, analyzing drawings, etc);

This internship is suitable for both apprentice and graduation assignments lasting 3 to 6 months, 4-5 days per week, starting from September.

Please note that we can only consider students who are enrolled at a university for the entire duration of the internship.

ASML: be part of progress

ASML is a high-tech company headquartered in the Netherlands. We manufacture the complex lithography machines that chipmakers use to produce integrated circuits, or computer chips. What we do is at the heart of all the electronic devices that keep us informed, entertained and connected. Every day, you use electronics that simply wouldn’t exist without our machines.

Behind ASML’s innovations are engineers who think ahead. The people who work at our company include some of the most creative minds in physics, electrical engineering, mathematics, chemistry, mechatronics, optics, mechanical engineering, and computer science and software engineering.

We believe we can always do better. We believe the winning idea can come from anyone. We love what we do – not because it’s easy, but because it’s hard.

Students: getting ready for real-world R&D
We’re a global team of about 29,000 people of 120 different nationalities and counting. Headquartered in Europe’s top tech hub, the Brainport Eindhoven region in the Netherlands, our operations are spread across Europe, Asia and the US.

In such an environment, your colleagues may be sitting next door, or they could be thousands of kilometers away in a different country – or even working for a different company.

An internship at ASML is the opportunity to get to know not only the world of industrial-strength R&D, but yourself – you’ll discover just what excites you most. Will you design a part of the machine, or make sure it gets built to the tightest possible specifications? Will you write software that drives the system to its best performance, or work side-by-side with the engineers of our customers in a fab, optimizing a system to the requirements of the customer?
How will you be part of progress?
