PhD-position: Synthesis and characterization of photoresists for Extreme UV lithography

In the photopolymerization group of prof. Liska at the Institute of Applied Synthetic Chemistry TU Wien (TUW) a PhD position is available for experimental research on photoresist development for extreme UV (EUV). This project offers exciting challenges to a PhD student who is interested to work at the interface between physics and chemistry, guided by an industrial application perspective.

The project is part of the Marie Skłodowska-Curie Innovative Training Network ELENA in which young researchers investigate the chemistry and physics involved in two emerging techniques for creating nanostructures: “writing” using electron beams, and lithography with light of very short wavelengths (“extreme ultraviolet”). ELENA participants are 8 academic institutions, 2 research institutes and 4 companies. Fifteen young researchers will be working in the network. Three secondments at partner laboratories are part of the training.

The photopolymerization group at the TUW aims to develop new photoresists for EUV lithography (EUVL). Photoresists are an essential element of photolithographic technology, because they transfer the pattern of irradiation to the underlying substrates with high precision, fidelity and throughput. In order to be able to write very small features, the use of radiation at very short wavelengths (Extreme UV, 13.5 nm) is currently the state of the art. For this wavelength, photoresists need to be designed and optimized. Our goal is to support this development with the synthesis and characterization of novel EUV resist materials.

Recently, photoresists have been proposed that are composed of hybrid organic/inorganic materials. The present PhD research project is focused on the synthesis and characterization of such materials. Our main tools are state-of-the-art synthesis techniques (Schlenk lines, Stock apparatuses and glove boxes) and characterization of the EUV photoresists using NMR, IR, gas chromatography, single crystal XRD, powder XRD and TGA instruments.

About the Division of Macromolecular Chemistry at the Institute of Applied Synthetic Chemistry:

In addition to basic research for the development of new methods and strategies of synthesis, the focus of the Division is on practice-oriented synthetic chemistry. The cornerstones of our activities are the synthesis and characterization of products that are industrially and technologically exploitable and marketable as well as the development of technical manufacturing processes. Our research is devoted to the synthesis and modification of synthetic polymers and renewable materials, whereas there is a strong focus on photopolymers, polymers and materials with defined architecture and biomaterials


You will need to meet the requirements for an MSc-degree to ensure eligibility for an Austrian PhD examination. Your field of study is Synthetic Chemistry or Physical Chemistry, and you have experience with polymerization (preferably radical and cationic) and the synthesis of resins and initiators. 

Additional requirements

Applicants shall, at the time of recruitment by the host organization, be in the first four years (full-time equivalent research experience) of their research careers and not yet have been awarded a doctoral degree. Full-Time Equivalent Research Experience is measured from the date when a researcher obtained the degree that would formally entitle him/her to embark on a doctorate.

Researchers can be of any nationality. They are required to undertake transnational mobility (i.e. move from one country to another) when taking up their appointment, as described by the Mobility Rule: at the time of recruitment by TUW, researchers must not have resided or carried out their main activity (work, studies, etc.) in Austria for more than 12 months in the 3 years immediately before the appointment date. Compulsory national service and/or short stays such as holidays are not taken into account.

A standard certificate of English language knowledge: for example IELTS, TOEFL, or equivalent. This requirement may be waived for applicants that have obtained Bachelor or Master degree, in which English was used as medium of instruction or for applicants that are citizens of countries, in which English is one of the official languages.

Terms of employment

The position is intended as full-time (40 hours / week) appointment for the duration of three years (starting in March 2017). The monthly minimum salary is EUR 2696.50- pre-tax, 14x per year. Several courses are offered, specially developed for PhD-students. After successful completion of the PhD research a PhD degree will be granted at the TUW.

In addition, the possibility for (co)supervision of students within the frameworks of Bachelor- and Masters-Thesis will be provided.

How to apply

Applications should be submitted in German or English language via e-mail to: christian.gorsche@tuwien.ac.at. Please send a single pdf-file, named “givenname_surname.pdf”. The deadline for application is: February 24th 2017.

Applications must include:

-) Cover-letter stating your motivation

TUW is an equal opportunity employer aiming to increase the proportion of women within scientific and artistic staff and thus strongly encourages qualified women to apply. Female applicants will be considered preferentially, if their abilities, aptitude and professional performance are equal with those of male applicants. Persons with disabilities are especially encouraged to apply.
