About The Company
Who are we? ASML is an innovation leader in the global semiconductor industry. We make machines that chipmakers use to mass produce microchips. Founded in 1984 in the Netherlands with just a handful of employees, we’ve now grown to over 40,000 employees, 143 nationalities and more than 60 locations around the world. What do we do? We provide chipmakers with hardware, software and services to mass produce patterns on silicon through lithography. Our lithography systems use ultraviolet light to create billions of tiny structures on silicon that together make up a microchip. We push our technology to new limits to enable our customers to create smaller, faster and more powerful chips. Who are our people? While you may think that only engineers and mathematicians work at ASML, you'll be surprised to find out that our people come from a wide variety of backgrounds. Across ASML, we have dedicated teams that manage customer support, communications and media, IT, software development and more. Every team in the company is essential for pushing our technology and the industry forward. If you love to tackle challenges and innovate in a collaborative, supportive and inclusive environment with all the flexibility and freedom to unleash your full potential, ASML is the place to be. Join us!
About the Role

Introduction

ASML YieldStar is an optical metrology tool that can quickly and accurately measure the quality of patterns on the wafer. In order to meet market-requirements we need to keep up to speed when it comes to pattern-recognition.

Your Assignment

For ASML’s YieldStar systems, a dedicated on‑tool software application is used to perform alignment diagnostics. This application, known as ADT, features a graphical user interface built with XAML. The tool requires maintenance, including bug fixing and implementing small feature requests coming from customers such as Intel.

ADT is a standalone application that reads its inputs from XML files stored on disk, processes these inputs, and presents the information in a clear, user‑friendly manner. In some cases, extensions to the XML output generated on the machine may be needed. These XML files are produced during a job run on the YieldStar system and can be quite elaborate.


Updating or extending them introduces some extra complexity, but with proper guidance, a motivated and capable intern should be able to handle it.
The XML format is “upgradable,” meaning that structural changes may require working with XSLT transformations as well.

Larger feature requests also exist and can be taken on depending on the intern’s progress and capabilities.

Keywords: XAML, XML, Image handling, Front‑end development, Bug fixing, Feature extensions, Independent working attitude.

The internship will contain:

  • Collaboration with stakeholders to finalize/crosscheck requirements
  • Coding in C#

Highlights:

  • Be part of one of the multidisciplinary teams in YieldStar
  • Experience working in a scrum team under the Scaled Agile Framework (SAFe), in an Agile Release Train
  • Be supervised by a software expert
  • Get to know more about the Software Development Life Cycle in a real-life product

This internship offers both technical and organizational challenges and will give the intern a very thorough view of how Yieldstar products are
created and how the R&D around it is organized.

Your profile

To be a match for this internship, you are a student in Vocational Education (MBO) ICT.

Other requirements you need to meet:

  • You are enrolled at an educational institute for the entire duration of the internship;

  • Attach your cover letter with a clear motivation why you are interested in this internship assignment in particular;

  • You need to be located in the Netherlands to perform your internship. In case you are currently living/studying outside of the Netherlands, your CV/motivation letter needs to include the willingness to relocate.
