Research & development - Leuven | More than two weeks ago
At imec our slogan is 'Embracing a better life’ and the way we do this is via nanoelectronics. Our chips are used for high-tech solutions that contribute to more efficient health care, safer transport, more sustainable energy, and more. A better world starts with the technology behind it and that technology is created in our cleanroom. In the electron microscopy group at imec we combine service and research. In the service we support the learning cycles by applying a variety of morphological, structural, and chemical methods. While in our research activities we are evaluating and/or developing new methods to characterize the increasing complex devices and materials used in our pilot line. As a postdoc researcher, you will push the boundaries of our research activities.
Imec is intensively investigating the emerging memory technologies for high speed, low energy consumption solutions compatible with the latest requirements in CMOS technology. Key for these technologies are ferroelectric materials. Traditional ferroelectric materials suffer from lack of thickness scaling and compatibility with CMOS processing. However, recently, thin binary oxides and III-nitride compounds have emerged as an attractive alternative due to CMOS compatibility and precise thickness control through atomic layer deposition. The ferroelectric response of these materials can be very complex and is affected by doping, extrinsic strain, electrode materials, and phase transformation. Also, the application of repeated electric fields may reduce the ferroelectric performance, leading to polarization reversal failure, i.e., ferroelectric degradation due to domain pinning and microcracks formation. To employ these materials in memory devices it is important to directly probe and characterize these effects. Scanning Transmission Electron Microscopy (STEM) is the most promising technique to fulfil the analytical requirements for these investigations due to the nanoscale range of these properties.
The goal of this position is to advance both the acquisition and data processing of phase and orientation mapping of ferroelectric materials by advanced TEM characterization methods such as precession electron diffraction (PED), differential phase-contrast (DPC) analysis and in-situ TEM.
During the postdoc the researcher will have the opportunity to work with Imec transmission electron microscopes on materials and structures that are being developed for future semiconductor device technologies.
The research will concentrate on:
