The post-doc will play a key role in understanding the device degradation by combining electrical characterization and modelling.
What you will do
In the last decade, oxide semiconductors have emerged as a higher performance replacement for standard amorphous silicon thin-film transistors (TFT’s) in display back-plane and flexible electronics. Among different material candidates, Indium-Gallium-Zinc Oxide (IGZO) is the most promising, providing high performance with large area uniformity, low off-currents and low-temperature processing. As a result of the exceptional electrical characteristics of this material, it is envisaged to use it in applications where standard Silicon technology cannot be employed due to process temperature constraints (power gating in the Back-End of Line) or has fundamental limitations such as leakage current (selector transistors in DRAM arrays).
However, the long-term reliability of IGZO devices is one of the most important aspects to be still fully characterized and understood before full deployment. The aim of this post-doc research is hence to study the overall IGZO TFT electrical reliability, targeting both logic and memory applications. To this end, this novel device must be fully characterized and modelled, from which fundamental understanding and possible reliability limitations are extracted, allowing for further process optimization and eventually the employment of these devices in real products. The post-doc will play a key role in understanding the device degradation by combining electrical characterization and modelling. Electrical characterization will take place within imec labs, in which the student will be responsible for developing his measurements routines and analyzing the subsequent measured data. The empirical activity should be followed by a modelling study to understand the device degradation and be able to forecast its lifetime.
You will closely work with the device process engineers to enhance the device reliability, and with the reliability team to develop and apply electrical characterization routines and subsequent data analysis and modelling.
