General Information

 The OCTOPLUS-O 350 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 350 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 350 plus various state-of-the-art components allow layer by layer precise MBE growth.

Outstanding features of the OCTOPLUS-O 350 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 350 comprises 8 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.

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.

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
