PLASSYS-BESTEK

PLASSYS-BESTEK, founded in 1987, is a French company providing high-performance vacuum and ultra-high vacuum solutions for innovative thin film material deposition. PLASSYS-BESTEK is a recognized leader in equipment for quantum technologies, having designed top-level deposition tools since the early 2000s that are now central to manufacturing superconducting qubits and other quantum devices. The company supplies custom-designed systems for prestigious research laboratories, universities, and industrial manufacturing plants. In October 2025, PLASSYS-BESTEK delivered the SQUID-6 UHV, a state-of-the-art quantum chip fabrication equipment, to Alice & Bob as part of the ULTRACAT project supported by France’s defense innovation agency (AID). The SQUID-6 UHV is a fully automated, ultra-high vacuum deposition system employing a modular cluster architecture that minimizes chip exposure to cross-contamination, reducing material imperfections and guaranteeing high-quality Quantum Processing Units (QPUs). PLASSYS’s core technologies include vacuum evaporation (thermal/e-beam), sputtering, and ion etching, along with production systems for diamond growth via PECVD. PLASSYS equipment is vital for applications in semiconductor technology, superconductors, nano-electronics, optics, photonics, and spintronics.
