Investigate the effect of microstructure on a freestanding membrane lifetime performance at ASML

Pellicle is a thin film membrane which is used in EUV scanner(NXE) and protect the mask from defects and particles. Pellicle is made of a poly-crystalline silicon film and working under harsh conditions (EUV light, plasma, vacuum and high temperature). In order to have a pellicle with robust performance and meet lifetime requirements, pellicle microstructure should be controlled and understood.

Your main task will be to use different characterization techniques such as HRSEM,TEM, EBSD, AFM to study a pellicle microstructure. You should be hands-on experiment. You should be able to use image processing techniques to quantify pellicle microstructure e.g. grain size and so on. In addition you need to correlate microstructure of pellicle with performance and build up understanding on pellicle performance drift during lifetime tests.

You are a  highly motivated student with material science and engineering background with high interest in analytical characterization. You should be eager to work in  team. You should be creative and innovative. Knowledge of programming language like Matlab/Python is a plus.

This is a graduation internship for 5 days a week with duration of a minimum 9 months.

Note that the outcome of this work cannot be published.

Please keep in mind that we can only consider students (who are enrolled at a school during the whole internship period) for our internships and graduation assignments .

Your internship will be in one of the leading Dutch corporations, gaining valuable experience in a highly dynamic environment. You will receive a monthly internship allowance of 500 euro (maximum), plus a possible housing or travel allowance. In addition, you’ll get expert, practical guidance and the chance to work in and experience a dynamic, innovative team environment.

We make machines that make chips – the hearts of the devices that keep us informed, entertained and safe; that improve our quality of life and help to tackle the world’s toughest problems.

We build some of the most amazing machines that you will ever see, and the software to run them. Never satisfied, we measure our performance in units that begin with pico or nano.

We believe we can always do better. We believe the winning idea can come from anyone. We love what we do – not because it’s easy, but because it’s hard.

Students: Getting ready for real-world R&D

Pushing technology further is teamwork, and our R&D team is more than 5,500 people strong, with major sites on three continents. Dozens of diverse, interdisciplinary teams work in parallel to meet a challenging development schedule.

In such an environment, your colleagues may be sitting next door, or they could be thousands of kilometers away in a different country, or even working for a different company.

An internship at ASML is your opportunity to get to know this world of industrial-strength R&D and get a feel for that excites you most. Will you design a part of the machine, or make sure it gets built to the tightest possible specifications? Will you write software that drives the system to its best performance, or work side-by-side with the engineers of our customers in a fab, optimizing a system to the requirements of the customer?

Afstuderen (MSc) bij IMS – Functional Optoelectronic Materials group

Material Discovery for Transparent P-Type Electrodes

*Option for Capital Selecta course: Introduction to Optoelectronic Materials (5 EC).

Project motivation: Metal oxides (MOx) are essential in several optoelectronic devices, such as thin film-based solar cells, displays and light emitting diodes. However, most conductive MOx are n-type. If a p-type counterpart is found, novel functionalities can be unlocked, such as the development of semi- or fully-transparent electronic devices, or the replacement of absorbing contacts in solar cells (Ref. M. Morales-Masis et al. Adv. Electron. Mater. 3 (2017)).

Project goal: Demonstrate experimentally recent theoretical predictions (Ref. G. Hautier et al. Nat. Commun. 4, 2013) that indicate that a transition from a metal oxide (MOx) to a metal oxysulfide (MOySz) or metal sulfide (MSx) leads to a transition from a n-type to p-type material.

Tasks of MSc student: Metal oxide thin films (SnOx, ZrOx) will be deposited by pulsed laser deposition (PLD), followed by a thermal sulfurization step. Optical and electrical characterization of the film’s properties as a function of oxygen and sulfur concentration will be performed and used to propose a model for carrier transport in the films.

Solution-Processed High-Mobility Transparent Contacts for Solar Cells

*Option for Capital Selecta course: Introduction to Optoelectronic Materials (5 EC).

Project motivation: Broad-band transparent and high-mobility transparent conducting oxides (TCOs) are required to maximize light absorption and electrical performance in solar cells. Gentle deposition techniques for the TCOs are required to avoid thermal or physical damage to the substrate or layers underneath, for example, during the deposition of the front TCO in solar cells (figure below) (Ref. M. Morales-Masis et al. Adv. Electron. Mater. 3 (2017)).

Project goal: synthesis of high mobility, wide band gap indium-based TCOs (H-doped In2O3, Zr-doped In2O3) thin films by chemical solution process. Films will be compared to PLD-grown films, to assess material quality, microstructure, dopant efficiency and carrier transport properties.

Tasks of MSc student: the films will be grown by chemical bath deposition (CBD) (or alternatively from nanoparticle-based solutions), and characterized by temperature-dependent Hall effect measurements, UV-Vis-NIR spectrophotometer, X-ray diffraction, AFM. Experimental data will be used to propose a carrier transport model. Application on proof-of-concept solar cells is also foreseen.

In the last 50 years the composition of natural gas in the Dutch gas grid was very constant. It is expected that the gas quality

bands are going to vary much more due to changes of the main gas supply streams, i.e. the introduction of biogas in the

gas grid will also lead to broadening of the gas quality bands. Although the used volume of biogas is relatively low, it can

cause variation because the gas quality of biogas varies periodically. This can cause a shift in the currently existing paradigm
