The OCTOPLUS-O 400 is very thoroughly designed for oxide layer deposition. The unique design with effective differential pumping allows depositing oxide layers in high Oxygen or Ozone partial pressure without strong degeneration of the hot sources. The OCTOPLUS-O 400 system can be easily adapted to small wafer segments as well as to 2 inch wafers. The field-proven vertical chamber design of the OCTOPLUS-O 400 plus various state-of-the-art components allow layer by layer precise MBE growth.

Outstanding features of the OCTOPLUS-O 400 are the special design, high reliability and versatility of the system and its compactness. These features make our systems particularly suited for applications in research and development. Nonetheless specific production processes are also covered.

The standard version of the OCTOPLUS-O 400 comprises 9 source ports 4.5 inch (DN63CF) flange size. A rapid pump-down load lock chamber with a horizontal working transfer rod system allows easy substrate introduction without breaking the vacuum of the MBE chamber.

Options for OCTOPLUS-O 400:

  • Additional load-lock and buffer chambers

  • Wafer transfer system

  • Sources: effusion cells, (multi-pocket) e-beam evaporators, etc.

  • Retractable sources for reloading without chamber venting

  • Upgrade from 9 ports up to 12 ports

  • Multiple turbomolecular pumps for differential pumping

  • Ozone source with or without enrichment

  • Oxygen plasma source

  • Software / hardware control system

  • In-situ characterization tools, e.g. ion gauge, quartz, pyrometer, RHEED, QMA

Ozone Source
Compact Ozone Source without enrichment up to 15% O3

We provide different kinds of effusion cells, valved cracker sources, gas sources and substrate manipulators according to customers' requirements.

CO2 laser heating allows substrate heating up to more than 1400°C.
A backside metal coating of the substrate is not needed, since the CO2 laser light is strongly absorbed by various oxide substrates.
Please see corresponding paper.

A well-manageable in-situ characterization is obtained by using quartz micro-balance, RHEED systems or quadrupole mass analyzers (QMA).

The OCTOPLUS-O 400 is in use in leading laboratories. On demand we transmit a detailed list of references.

Zone 1 (blue coloring):

  • Oxide deposition area

  • High O2 and O3 partial pressure

  • Ozone injector ring close to substrate

  • Short distance of Ozone injector to substrate

  • Low Ozone consumption

  • Ozone resistant SiC heater

  • Strong differential turbo pumping

Zone 2 (yellow coloring):

  • Source area

  • Low pressure due to small opening towards zone 1

  • Separate strong turbo pump

  • Pressure significantly lower than in zone 1

  • Shutters with low flux transient

  • Low efficient individual differential pumping of each source not needed

  • Integration of multi-pocket e-beam evaporator possible
