Are you a student in Software Engineering or Computer Science? Do you have knowledge in Python and C++? Are you proactive? Then this internship might be interesting for you!

Background information

In order to meet the tighter requirements on imaging performance, it is of great importance to always image the patterns in the available depth of focus. One prerequisite of tight focus control is the knowledge of the wafer topography. For that purpose a dedicated sensor is present in the machine, which measures a height map of the wafer with an accuracy of a few nanometers.

The main purpose of this wafer map is to determine the wafer stage trajectories during the exposure of the wafer in order to keep the wafer in best focus all the time. A verification test has been designed for checking the accuracy of the measured wafer map and troubleshooting potential issues.

Your assignment

While we currently have a verification test, implemented in Python with some backend code in C++, there are some improvements/extensions that could be made to make the tool more useful to design engineers, whether carrying out experiments on prototypes systems or debugging / diagnosing issues.

The aim of this internship will be to implement some of these features, discussing with domain experts to ensure the design, operation and testing of these features is in line with expectations, and delivering these extensions to our software archive so that they are available on all Twinscan platforms.

Examples of the additional functionality include:

  • Histograms of calculated metrics (reproducibility/accuracy) across the wafer area;
  • Update of graphical user interface to include additional options, such as wafer rotation;
  • Validation of the options selected by the user, preventing inconsistent settings.

Your profile

To be the perfect match for the internship, you:

  • are a student in Software Engineering, Computer Science, or Physical Sciences;
  • have knowledge in Python, C++ and behavioural testing;
  • are proactive and have great communication skills in English, both written and verbally.

This is a bachelor apprentice internship, with a minimum duration of 6 months, 4 days per week, starting as soon as possible.

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

This position requires access to U.S. controlled technology, as defined in the United States Export Administration Regulations. Qualified candidates must be legally authorized to access such U.S. controlled technology prior to beginning work. Business demands may require ASML to proceed with applicants who are immediately eligible to access U.S. controlled technology.

Change the world – one nanometer at a time
Become an intern at a Dutch company that’s a global industry leader. You’ll gain valuable experience in a highly innovative environment – one that sparks your imagination and creativity. In addition to a monthly internship allowance of maximum €600 (plus a possible housing and/or travel allowance), you’ll get practical guidance from experts in the field and the chance to work in and experience a dynamic team environment.

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?
