Over the past 60+ years, CMOS-based digital computing has led to ever-increasing computing power, big data based business models, and accelerated digital transformation of the modern economy. But ever-increasing data volumes and the growing complexity of today's computing tasks are pushing us to limits in terms of data processing and energy consumption. We need new concepts and technologies - for example, quantum computing (QC).

Quantum computers use so-called quantum bits (qubits) to perform complex calculations fundamentally much faster than a conventional digital-bit computer can. The first prototypes of quantum computers have already been created. Novel materials for these qubits are currently being researched. The MATQu project sees a major challenge, but also opportunity, to create a complete value chain for semiconductor-based qubits and quantum computers in Europe. Therefore, the project aims at developing the necessary technologies to establish industrial 300 mm silicon-based process flows. This includes substrate technology, superconducting metals, resonators, through-wafer vias, 3D integration and characterization.

Fraunhofer IPMS' focus in the project is to bring existing concepts and technologies from the laboratory to industrial manufacturing. In doing so, the institute invokes its expertise in 300 mm fabrication, which already serves as an industry standard for CMOS computing platforms. The project will provide new insights into the material and process influences for the fabrication process of superconducting qubits, especially in the area of deposition, patterning and the overall integration approach of superconducting layers. Novel fabrication processes and testing at cryogenic temperatures will enable the fabrication of devices suitable for quantum computing on a European scale. Fraunhofer IPMS will also work with industrial and research partners to provide European SMEs and startups with access to state-of-the-art manufacturing facilities and know-how to significantly increase the maturity of superconducting qubit technology and strengthen the European quantum technology ecosystem.

This project leading to this application has received funding from the ECSEL Joint Undertaking (JU) under grant agreement No 101007322The JU receives support from the European Union’s Horizon 2020 research and innovation program and Germany, France, Belgium, Austria, Netherlands, Finland, Israel.
