Postdoctoral Researcher Atomic Layer Deposition for Memory Technologies

You will gain fundamental understanding of ALD growth mechanisms, needed to develop materials for application in next generation memory devices.

What you will do

Imec investigates memory concepts with increased memory density to enable fast, low temperature and powerful storage solutions for next generation smart phones, tablets, smart TVs, and other pioneering technologies. These include DRAM devices for high-speed access, NAND flash memory devices for storage of large amounts of data, and the emerging Storage Class Memories (SCM) for massive data access in short time. Each technology requires specific materials. Moreover, the deposition of these materials is challenging due to the high aspect ratios in advanced 3D architectures. Atomic Layer Deposition (ALD) is a promising technique in this respect, as it allows for conformal deposition of a wide range of materials. The aim of this post-doc project is to generate fundamental insights into the growth mechanisms of ALD, focusing on materials that are relevant for various memory applications. Germanium chalcogenides are promising materials for SCM, as phase-change-based memory material and as selector material. However, complex ternary and even quaternary compounds are needed to improve the stability and boost the memory cell performance. For NAND flash on the other hand, we will explore alternative channel materials with high carrier mobility such as (In)GaAs. Fundamental understanding of the ALD growth mechanisms and the impact of precursors will be key to control the composition and properties of these complex materials, and as such optimize the memory device performance. The Thin Films group of imec is looking for a self-motivated professional with deposition (ALD or CVD) and material background, who can work in a cross-functional team of people dedicated to the development and integration of memory-oriented materials.
