Co-op Materials Engineering Spring 2026 (Internship)

Introduction

ASML US brings together the most creative minds in science and technology to develop lithography machines that are key to producing faster cheaper more energy-efficient microchips. We design develop integrate market and service these advanced machines which enable our customers - the worlds leading chipmakers - to reduce the size and increase the functionality of their microchips which in turn leads to smaller more powerful consumer electronics. Our headquarters are in Veldhoven the Netherlands and we have 18 office locations around the United States including main offices in Chandler Arizona San Jose and San Diego California Wilton Connecticut and Hillsboro Oregon.

ASML is seeking a co-op student to join the Defectivity Group in the Wilton CT location. Within ASML the Development & Engineering (D&E) sector is responsible for the specification and design of ASML products.

The Defectivity group is responsible for creating the perfect environment within the vacuum reticle modules in cutting edge EUV lithography machines. We take many approaches such as designing the gas flow in vacuum choosing the correct materials and designing cleanliness processes.

As ASML pushes the boundaries of nanotechnology beyond current state of the art we need to study nanoparticle behavior in new ways. We are looking for someone to help pioneer knowledge in this developing area.

Your assignment

Design of experiments for a wide range of project needs.

Derive conclusions from analysis to make practical recommendations.

Technical writing and communication skills including the ability to present results based on scientific evidence to audiences of a wide range of technical abilities

Take direction from ASML System Architects and Senior Engineering mentors who are leading the development effort of critical large capital equipment.

As a co-op in the Defectivity group you will participate in developing portions of the lithography system and / or associated tooling and test equipment. You will work on sub-systems involving robotics mechatronics precision mechanics and / or opto-mechanics. You will need to consider engineering specifications and performance lifetime failure modes root cause analysis statistical analysis measurement system capability etc.

You will collaborate with system architects and engineers in a multidiscipline project team to develop concepts perform engineering analysis build and test prototypes design experiments and / or analyze data.
