Integration of advanced materials on silicon: from classical to neuromorphic and quantum applications

The symposium aims at gathering scientists working on monolithic and heterogeneous integrations of new materials, to enable additional functionalities on silicon-based platforms. It considers both classical approaches and emerging topics linked to neuromorphic and quantum applications. The various research fields covered in the symposium pave the way towards highly functionalized Sibased technologies which address current and future challenges in our society.

Scope:

The microelectronics industry has delivered faster and more efficient computing devices at a remarkably consistent pace for several decades. More recently, the demand for high performance devices and mass data transfer has soared. Driven by new societal needs, linked to the “Internet-ofthings” and the growing demand for ultra-fast data transfer, cognitive systems and new computing paradigms, such as neuromorphic and quantum information processing, have been developed.

Industrials are therefore looking beyond classic architectures and concepts to secure future generations of devices that can be integrated with conventional silicon chip platform. Neuromorphic networks for example require dense arrays of interconnected devices, patterned on silicon using the processing know how generated by the conventional industry. For quantum information science, silicon is also emerging as a promising route. Even for emerging materials that are not yet widely used in the industry, like topological insulators, quantum-dots structures, magnetic or superconductor materials, silicon could be a platform of choice for device integration.

The symposium aims at highlighting novel and innovative approaches that allow for monolithic and heterogeneous integration on silicon technology, application-specific integrated solutions (based on integrated photonics, neural networks, spintronic devices...) or quantum systems. The scope includes the fundamental understanding of new material properties, the implementation of novel integration schemes, the modelling techniques and new application fields. The focus will be on the fabrication, characterization and simulation of materials considered as non-standard for Si technology. Contributions related to innovative hetero-integration techniques will be encouraged. Finally, a particular attention will be given to devices and applications beyond current computation technologies that aim at addressing new computing paradigms such as quantum and neuromorphic computation.
