Integration of memristive materials on Si

This project involves the synthesis of memristive devices on up to 4 inch Si substrates to facilitate the integration of this technology on CMOS. We plan to fabricate heterostructures consisting for example of a SrRuO3(SRO) bottom electrode, (PR, Ca) MnO3(PCMO) insulator and a TiOx/Ti and Pt top electrode. The PCMO/TiOx interface is most important for the resistive switching mechanism and scalability. The SRO/PCMO/TiOx/Ti/Pt heterostructures are grown and processed on single crystalline SrTiO3(STO) substrates and Si wafers (10*10mm2and 4”) with appropriate buffer layers. The main part of the research will be performed at the University of Twente, the Netherlands. Additionally, the ESR will spend the secondments at Forschungszentrum Jülich, Germany for thesynthesis of memristors (1 Month), at Twente Solid State Technology B.V., the Netherlands for the integration on Si (3 Month) and at IBM Research – Zurich, Switzerland for Si based memristors Integration on CMOS (1 Month).

The University of Twente is an entrepreneurial research university founded in 1961 in the eastern part of the Netherlands. The MESA+ Institute for Nanotechnology is a spearhead research institute at the University of Twente. It is one of the largest nanotechnology research institutes in the world, delivering competitive and successful high quality research. With its NanoLab facilities the institute holds 1250 m2of cleanroom space and state of the art research equipment. MESA+ combines the disciplines of materials science, physics, electrical engineering, chemistry and mathematics.

The state of the art knowledge of advanced functional oxides and other inorganic materials in nanostructures, such as thin film heterostructures, superlattices, multilayers, composites and nanowires, and the expertise on thin film and 2-dimensional oxide materials and characterization, make the MESA+ Institute for Nanotechnology at the University of Twente an excellent setting for the present proposal.
