ASML
Internship: Create a framework for processing Seismic Simulation Results
Introduction
This is an internship for a master's student in Mechanical engineering, Dynamics and Control or Applied Physics who is interested in developing a methodology that can be used to process Seismic Simulation Results.
Job Mission
The main challenge of ASML is to make it possible to produce smaller chips that are more sustainable and powerful, while processing more information. To establish this, ASML machines should continuously be improved on positioning requirements of mechanical devices and machine throughput.
This is the responsibility of the Mechanical Analysis department (part of Research & Development). Within this department, a group of 40 engineers is responsible for executing mechanical analysis such as the dynamic behavior of machine-parts and (sub)systems.
By the usage of FEM models and model reduction techniques a complete ASML machine is modeled such that a transient Seismic disturbance can be applied to it.
A lot of data in the form of time domain signals is generated from such a Seismic Simulation which takes considerable work to post-process and present because of the complex nature of ASML machines and the transient nature of the Seismic disturbance.
A framework needs to be put in place to organize and interpret this data in a meaningful way in both time and frequency domain. Basic signal processing techniques like detrending/filtering need to be applied to clean up the signals. However this can be tricky because if designed too aggressive useful data can be lost.
The main scope of work is to develop a methodology to represent the data at an ASML module level through the use of custom MATLAB tools such that a quick overview of the data can be obtained and a meaningful interpretation towards judging the impact of the seismic event can be made.
