Data Science Internship: Data-driven modelling and identification of wafer tables

Introduction

The Tables & Clamps Analysis group within ASML’s Development & Engineering (D&E) department is offering an exciting internship opportunity. As an intern, you’ll be part of a dynamic, multidisciplinary team focused on developing, analyzing, qualifying, troubleshooting and improving Wafer Tables/Clamps (WT/C).
 

In lithography machines, silicon wafers are kept in place on the WT/C during exposure. The surface condition of the WT/C directly impacts the clamped wafer distortion levels therefore affecting the printed pattern quality and customer satisfaction. Data is collected from factory and customer machines to characterize the performance of the wafer tables. Analysis based on that data impacts internal machine optimization, maintenance actions, future designs, and overall market trends. 

Your assignment

Several models of WT/C have been installed in customer machines over time, with different design and surface properties. Customers then apply different processes to their wafers, causing different types of interactions between the WT/C and the wafers.

The assignment is to use the data gathered from the machines in the field to relate the performance of the WT/C to the original design properties. We expect a data-driven model which can identify the original WT/C from their field data. This will be used to identify unregistered or unknown WT/C installed in the machines, and if possible to predict performance their performance given factory data.

This is a master apprentice internship for 6 months, with the possibility for extension. The start date of this internship is as soon as possible or September.

Your profile

To be a perfect fit for this assignment, you:

• Are pursuing a degree in Data Science, Statistics, Mathematics, Computer Science/Engineering, Mechanical Engineering (with a strong interest in data analysis), or a related field;
• Have excellent MATLAB or Python knowledge as an implementation software;
• Preferably have prior knowledge of machine learning and statistical model validation;
• Have strong analytical and problem-solving skills;
• Are proactive and comfortable in reaching out to experts, arranging support independently and researching literature where needed;
• Have good communication skills and willingness to work independently.

Other requirements you need to meet:

• You are enrolled at an educational institute for the entire duration of the internship;
• You need to be located in the Netherlands to perform your internship. If you are currently living/studying outside the Netherlands, your CV/motivation letter must include your willingness to relocate;
• If you are a non-EU citizen studying in the Netherlands, your university must be willing to sign the necessary internship documents (e.g., Nuffic agreement).
