Job description

At KAI (Kompetenzzentrum Automobil- und Industrieelektronik GmbH), you will perform your thesis project in an industrial research environment, guided and supported by experienced researchers. We work in close cooperation with universities and research facilities supporting your academic education, whereas our industrial partner Infineon offers interesting opportunities for a prospective career path in the semiconductor industry
Infineon is a global leader in the production of power semiconductors. The manufacturing of semiconductor devices is very complex process consisting of a sequence of individual processing steps, each effecting the device performance
A scanning electron microscope (SEM) is a state-of-the-art tool to visualize materials with a high spatial resolution. Dedicated techniques such as electron channeling contrast imaging (ECCI) and electron backscatter diffraction (EBSD) can be applied to visualize the lattice strain, orientation as well as single defects in semiconductor materials. The aim of this thesis is to evaluate these techniques on test structures in order to optimize the sample preparation and the SEM settings for the investigation of semiconductor materials. Subsequently, the optimized methodology will be applied to Si and SiC dies, to investigate the impact of industrial processing (e.g. wafer separation). Finally, the materials characteristic should be correlated with processing parameters to understand their impact on the chip robustness.
KAI GmbH in cooperation with Infineon Technologies Austria AG is involved in the FFG General Program project ARCADE for implementation of advanced characterization concepts into the industrial environment of power semiconductor manufacturing. Within the framework of this project we offer this master's thesis within the Materials Science & Simulation group (KAI MSS) in Villach.

In your new role your new tasks will be:

• Preparation of samples to enable materials characterization using SEM
• Evaluation of state-of-the-art electron microscopy techniques (EBSD,ECCI) to analyze semiconductor materials
• Optimization of the applied methodology (sample preparation, characterization technique)
• Investigation of the microstructure, lattice strain and defects in semiconductor materials (Si, SiC) after individual manufacturing steps
• Correlation of the materials characteristic and the industrial processing
• Documentation of the results and preparation of a master's thesis

This thesis has to be written in cooperation with a university.
