Fraunhofer is responsible for examining the electrical performance of semiconducting devices in cryogenic environment.
Fraunhofer is involved in ARCTIC with its Institutes for Photonic Microsystems IPMS and for Applied Solid State Physics IAF. Their focus within the project lies on the characterization of semiconducting devices in cryogenic environments and peripheral devices for cryogenic quantum computing processors on full wafers as well as the analysis of the electrical behavior of transistors and memory devices at untypically low temperatures.
Fraunhofer IPMS is dedicated to applied research and development at the highest international level in the fields of photonic microsystems, microsystems technologies, nanoelectronic technologies and wireless microsystems. Its business unit Center Nanoelectronic Technologies (CNT) will contribute to ARCTIC by its large competences in the electrical characterization of experimental and commercial semiconductor devices, including capabilities for electrical defect and RF/mmWave characterization at room and cryogenic temperatures. Examined devices will be commercial FETs in 22FDX FDSOI and 28SLP technology, heterojunction bipolar transistors, ferroelectric three-terminal memories (esp. FeFETs) and other non-volatile memories.
Fraunhofer IAF is dedicated to innovative hardware for quantum computing, cryogenic electronics, diamond-based quantum sensors, high-frequency circuits for communication technology, energy-efficient voltage converter modules for electro mobility and laser systems for spectroscopy. As one of the leading research facilities worldwide in the area of III-V semiconductors the institute covers the entire value chain. Their core competences range from materials research, design, technology and circuits, especially full-wafer testing, to modules and systems. Alongside its extensive knowledge in characterization methodologies for semiconductor device for R&D purposes up to industrial tests of 200 mm and 300 mm wafers, Fraunhofer IAF is one of the very few European providers of such low temperatures test set-up below 2 Kelvin. This profound knowledge about cryogenic device characterization and statistical variability of key technologies is integral in accelerating the industrial testing of cryogenic technologies necessary to scale up quantum computing.
On top of this technical work, Fraunhofer is coordinating the work within Task 3.1 of work package 3.
