GRENOBLE, France – Feb.4, 2021 – CEA announced today the acquisition of a Cryogenic Wafer Prober manufactured by Bluefors Oy, the Finnish specialist in designing and manufacturing ultralow temperature-dilution refrigerator systems for cutting-edge research in quantum computing and nanotechnology. CEA-Leti, a technology research institute at CEA, is the first microelectronics research institute to install this strategic equipment in its cleanroom.

Created by Bluefors Oy and the Finnish company Afore, the cryogenic prober is a tool that enables fully automatic measurements of 300mm wafers at temperatures below 2K. This new tool allows up to 100x faster throughput in sample characterization than existing systems and is expected to dramatically accelerate development of cryogenic quantum devices, electronics and detectors. It will be used to characterize CEA-Leti's silicon-based qubits, measuring their performance at temperatures between 2K and 4K, extendable to 20K. This acquisition will be used on CEA-Leti's 300mm wafer-fabrication line.
