Deposition100mmPfeiffer ATH1603M family
Research Quality: 40% complete

The Pfeiffer ATH1603M is a magnetically levitated turbomolecular pump with a pumping speed of approximately 1,400–1,600 l/s for nitrogen. The ATH1603M achieves an ultimate pressure of up to 6×10⁻⁹ mbar and operates at 39,000 rpm. The ATH1603M is used as a secondary pump in vacuum systems, such as the Alliance-Concept EVA 451 thermal evaporator.[1][2]

What it is

The Pfeiffer ATH1603M is a turbomolecular pump designed for generating high and ultrahigh vacuum.[2][1]

How it works

The ATH1603M achieves an ultimate pressure as low as approximately 6 × 10⁻⁹ mbar, depending on the system configuration.[1]

The pump is water-cooled and requires an external controller; it does not include an integrated drive electronics unit.[1][3]

Complementary dry pumps used in the same system include the Pfeiffer ACP series for primary pumping.[2]

What can it run?

Process applications and technology nodes documented for this tool.

  • Used in the pumping system of an evaporator for coating conductive layers
  • Associated system is used to prepare non-conductive samples for e-beam exposure and avoid charging issues
