Stand alone Solutions |
EBARA’s Roots pumps (e.g. ESR80WN) ideally fit the needs for poly silicon production. EBARA’s screw pumps AAS100WN / EST100WN are meeting the harsh process requirements for SiN and diffusion processes. EBARA’s G5 burner washer abatement system is the state-of-the-art technology, e.g. for POCl3 abatement in SiN processes.

OEM and Turnkey Solutions |
EBARA’s A200WN, ESA500WN, ESR300WN and ESR500WN Roots pumps can be combined to big pumping stations to pump down the heavy gas load of equipment for TCO processes and for amorphous/microcrystalline tandem thin film layer formation. These pumps provide the highest customer benefit in terms of uptime, energy consumption and cost of consumables.
On the abatement side for TCO and tandem thin film layer formation, the burner washer type G5 abatement and the silane dynamic oxidizer S-DOC, combined with a particle filter are the most advanced solution ensuring maximum uptime and ease of waste removal. |

A very specific solution of abatement technology is required for H2S/H2Se removal in CIS processes. The tool of choice to ensure the safe handling of toxic H2Se is an Airgard water scrubber, combined with a taylor-made waste water treatment system to neutralize the toxicity.
In addition to our highly competitive products and turnkey solutions, EBARA Precision Machinery Europe offers project planning, system engineering, installation, maintenance, consulting and training, incorporated in a worldwide support network at the major PV industry sites.
