Postdoc RRAM Material and Process Development
Employer: imec
Location: Leuven, Belgium
Employment Start Date: As soon as possible

Organization Description:

Imec is the world-leading research and innovation hub in nanoelectronics and digital technologies. The combination of our widely acclaimed leadership in microchip technology and profound software and ICT expertise is what makes us unique. By leveraging our world-class infrastructure and local and global ecosystem of partners across a multitude of industries, we create groundbreaking innovation in application domains such as healthcare, smart cities and mobility, logistics and manufacturing, and energy. As a trusted partner for companies, start-ups and universities we bring together close to 3,500 brilliant minds from over 70 nationalities. Imec is headquartered in Leuven, Belgium and also has distributed R&D groups at a number of Flemish universities, in the Netherlands, Taiwan, USA, China, and offices in India and Japan. All of these particular traits make imec to be a top-class employer. To strengthen this position as a leading player in our field, we are looking for those passionate talents that make the difference! Currently we are looking for a motivated Postdoc RRAM Material and Process Development. In exchange for your talent, passion and expertise, you will join a multicultural and high-tech company, with challenges there for the taking. Our flexible, progressive and informal working environment offers you a range of possibilities to take initiative and show responsibility. This is your opportunity to contribute to the technology that will determine the society of tomorrow. imec supports and guides you in this process; not only with words but with concrete actions. Through, 'our corporate university', we are actively investing in the further development of all our employees to assure their technical and personal growth. This postdoctoral position is funded by imec through the KU Leuven. Because of the specific financing statute which targets international mobility for postdocs, only candidates who did not stay or work/study in Belgium for more than 24 months in the past 3 years can be considered for the position (short stays such as holiday, participation in conferences, etc. are not taken into account).

Job Description:

For future semiconductor memory technology nodes, different concepts are being explored for storage class memory. One of today’s most promising alternative concepts for scaled memory is RRAM (Resistive RAM) which is based on the electronic switching of a resistor element. The combination of this memory element with a diode-type selector device results in a highly scalable RRAM memory cell. The memory element as well as the selector require multi-element compound materials the detailed composition of which is determining for its performance in a memory cell. The integration of these memory cells in 3D cross-bar arrays can only be accomplished with a deposition technique that insures excellent step coverage in 3D device structures, i.e. Atomic Layer Deposition (ALD). In this post-doc, you will focus on OTS-type of materials (Ovshinsky Threshold Switching), more in particular the family of so-called chalcogenide glasses. In collaboration with chemical precursor and ALD tool suppliers, you will develop an ALD process for germanium chalcogenides in our state-of-the-art 300mm clean room. In order to improve the thermal stability of these amorphous layers, you will explore doping of these materials with ternary/quaternary elements. This should result in a material strategy in order to reach the targeted device specifications, in close collaboration with the integration engineers in imec’s Emerging Memory program. As part of the material development, you will also take care of the physical and basic electrical characterization of the deposited layers.


You have a PhD degree in Physics, Materials Science or Engineering. - You have a strong materials background, relevant for this topic. - Hands-on experience with deposition techniques is a plus. - You have experience with physical and electrical characterization of such materials. - You can easily integrate in an international team of professionals. - You have excellent English communication and reporting skills
