Qubit multi-chamber systems

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. Several 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 based superconducting films

  • Evaporation UHV chamber

  • Oxidation 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.
