What Plassys Bestek does
Plassys Bestek is a French privately-held SME founded in 1987, headquartered in Marolles-en-Hurepoix, France, that designs and manufactures vacuum and ultra-high-vacuum (UHV) thin film deposition systems. The product portfolio centers on six platform categories: MEB-Ebeam electron beam evaporation systems, MP-Sputtering magnetron systems (incorporating IONAUTICS HiPIMS), ME-Thermal evaporation systems, MPCVD diamond reactors (SSDR150 and SSDR400), customized multi-technique tools, and the proprietary Dalek™ control and monitoring software. Sub-brands QUTEK™ (quantum deposition) and DIAMTEK™ (lab-grown diamond CVD) extend the portfolio into vertical-specific offerings.
The company's commercial focus is heavily weighted toward the global quantum computing research ecosystem, where its UHV electron beam systems are used to fabricate superconducting qubits, Josephson junctions, and related quantum hardware. Published peer-reviewed results cite PLASSYS UHV systems in achieving record transmon coherence times (T1 up to 1.68 ms at Yale) and fluxonium qubit coherence (0.5 seconds with Alice & Bob). Secondary verticals include synthetic diamond growth, MEMS, spintronics, EUV optics, plasmonics, lithium battery research, and defense applications, with the French Ministry of Defense supporting the SQUID6 UHV cluster tool development.
The company operates a hybrid go-to-market combining direct enterprise sales with a network of six authorized regional distributors covering Germany/Austria, India, Singapore, Japan, Mainland China/HK/Macau, and Taiwan. Approximately 80% of business is export-driven, systems are delivered to 30+ countries, and cumulative deliveries exceed 500 units. Pricing is contact-based and project-specific with no public disclosure; revenue streams include hardware sales and an emerging installed-base refurbishment and maintenance service line operated through approved partner ApSy – Application Système.
