- Applications: III/V, II/VI and other heterostructures
- 12 source ports
- Wide range of source options, e.g. effusion cells, gas sources, manipulators
- Substrate sizes 2", 3" or 4"; face-down wafer geometry
- Strong UHV pumping system
- LN2 cooling shroud
- In-situ characterization capability
- Strong support by PhD MBE experts
The OCTOPLUS 500 system was developed for the growth of high quality III-V heterostructures on 4 inch Si substrates. Optionally the system can be upgraded to 6 inch substrate size. The MBE chamber is equipped with up to 12 effusion cells or gas injectors for deposition or surface treatment.
The substrate manipulator applies to pyrolytic graphite or alternatively tungsten or tantalum heaters. The OCTOPLUS 500 MBE system is field-proven and ideally suited for III/V, II/VI and other heterostructure growth for applications in research and production processes.
Outstanding features of the OCTOPLUS 500 are the high reliability and versatility of the system.
The standard version of the OCTOPLUS 500 comprises 12 radially arranged source ports, 3 further source ports can be added on request. A rapid pump-down load lock chamber with a horizontal working transfer rod system or a central transfer module allows easy substrate introduction without breaking the vacuum of the MBE chamber.
Options for OCTOPLUS 500:
- Additional load-lock or buffer chambers
- Wafer transfer system
- Effusion cells, e-beam-evaporators, sublimation sources, valved cracker sources, gas sources, manipulators
- Software/hardware control system
- Pumping system (turbo molecular pumps, cryopumps, ion getter pumps, etc.)
- In-situ characterization tools, e.g. RHEED, BFM, Quartz, Pyrometer
- Additional requirements
