Background Information

The Machine Control (MC) department is responsible for the definition and handling of the Exposure Recipe. Exposure Recipes are used by ASML customers to define the structure and layout of the wafer along with settings needed to correctly process wafers in the Lithography machine.
With the growing number of productivity enhancement packages offered by ASML, we can expect the number of settings provided by our customers to increase every year. As these packages are available in our different platforms (e.g. NXE, NXT, XT) we are already approaching the memory and performance limits.
A redesign is needed in the proprietary data structures that we use to distribute costumer settings internally throughout the Twinscan. Enter DCA and CDM.

DCA stands for the architectural pattern of separating Data, Control and Algorithms & actions, and is intended to improve the efficiency of data sharing between tasks, both in execution and development. 
DCA recognizes that data definitions are only meaningful in a given domain context.

Within a particular domain (e.g. Twinscan), multiple specialized domain contexts may be identified, e.g. ‘Leveling’, ‘Wafer Handling’ and ‘Exposure’. Some concepts in these contexts may be meaningfully shared across context boundaries. The set of key Twinscan concepts useful for almost any other Twinscan domain context are (to be) implemented in the Core Data Model (CDM). 

The CDM is envisaged to represent two groups of data:

  • Run-time data - data that is created as a result of the execution of a Lot or other task (typically Internal control data, Output data or Settings and calibration data);
  • Settings data - data that derived from user-provided Task/Lot input data, configuring TWINSCAN Task/Lot execution. This data is created when adding Lots to the queue and must therefore be persisted to cover machine restarts (if any) occurring before Lot execution.

Your Assignment

The goal of this assignment is to investigate the implementation of the settings data model in CDM and how this can replace the current way of working. The task consists of:

  • Understanding the problem, specifying the main use cases and corresponding requirements;
  • Defining the settings CDM;
  • Investigate how our current way of working can be migrated to make use of the settings CDM;
  • Define a structure that maintains the flexibility of the current one.

Your Profile

To be the perfect match for this internship you:

  • Are a master student in computer science;
  • Have experience in Data Modeling;
  • Have experience with C++
  • Are eager to learn and like a challenge.

This is a master graduation internship lasting 6 months starting September 2023.

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

Other Information

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 coverage), 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?
