Introduction

Are you a student with a background in Chemistry, Physics, Materials Science or Mechanical Engineering? Do you have knowledge of polymers and polymer manufacturing? Do you have an analytical approach and are you a self-starter? Then this internship might be interesting for you!

Background information

Wafer Defectivity in EUV is one of the major yield detractors for our customers. The particles found on the front side of the wafer are characterized by SEM/EDX at the customer sites. As SEM/EDX is an elemental analysis, it is a major challenge to assign polymeric particles to parts in the bottom cluster module for root cause analysis. Since these particles are generated mostly by wear, the morphology of the particles could also play a role in the assignment of root causes. Identification would be facilitated if a catalogue of particles from known polymeric parts characterized with SEM/EDX was in place. This assignment is to prepare this catalogue.

Your assignment

This assignment consists of two parts:

The first part is to identify the relevant wear mechanisms and propose how to replicate these offline on material samples. Initial suggestions are diamond pin scratching after nitrogen freeze, pin on disc wear, or simple contact pressing against a hard surface.

The proposal has then to be executed in the cleanroom where the candidate is expected to carry out the following activities:

  1. Generate particles via the proposed methods using relevant material samples.
  2. Characterize the particles generated using metrology tools such as SEM/EDX and microscopy

The second part of the assignment will be the preparation of the particle catalogue and will include the following activities:

  1. Validate the offline particle generation methods by comparing the particles generated for each polymeric part to those from the field data known issues.
  2. Comment on the best fit, the best particle generation methodology and as a consequence, the possible wear mechanism in the EUV system.

Your profile

To be the perfect match for this internship, you:

  • are a master's student with a background in Chemistry, Physics, Materials Science or Mechanical Engineering;
  • have knowledge of polymers, polymer manufacturing, wear mechanisms or tribology;
  • have an analytical approach and are a self-starter;
  • have great communication skills in English, both written and verbally.

This is a graduation internship for master students, with a minimum duration of 9 months, 5 days per week. The start date is 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.
