Systems for qubits and other quantum applications

The quantum computer will be one of the most revolutionary technological advancements of the next decade, (if not of this one’s). In the whole world, many scientific and R&D centers have consistent human and material resources fully dedicated to this quest.

PLASSYS is on par with the rapid development of the qubit devices and proposes a series of systems specifically designed for Josephson Junctions deposition. More than 10 multi-chamber systems have already been sold world-wide and the feedback of our customers has been used for further development of the technology put into our machines.

Multi-chamber and multi-technology HV/UHV systems for 4’’ to 8’’ samples:

  • Load-lock for sample loading/unloading

  • Optional UHV sputtering chamber for Nb an Ti based superconducting films

  • Evaporation UHV chamber

  • Oxidization UHV chamber

The transfer between chambers is ensured by rods and/or articulated arms and both mechanisms are available in manual or automatic mode. Transfer valve operation (open/close) is automatically managed by the system.

Transfer rod UHV compatible
