Order for a production machine in Russia

Bezons, France, April 6, 2010 – 5.45 pm – RIBER, the global leader for molecular beam epitaxy (MBE), announces the sale of a production system to LLC Connector Optics, a company based in St Petersburg in Russia.

The acquisition of an MBE49 system by a Russian semi-conductor industry participant confirms RIBER's global leadership in the field of MBE – Molecular Beam Epitaxy).

RIBER systems provide great flexibility in processing large-size substrates (multi 4 and multi 6-inches) to grow III-V semi-conductor based nanostructures. The MBE49 machine acquired by LLC Connector Optics will be dedicated to manufacturing innovative VCSELs (Vertical Cavity Surface Emitting Lasers) and photodetectors for optical data communications.

The MBE49 model is by far the most adapted system to the production of highly demanding nitride-based optical components, due to its unique deposit quality, mono-atomic precision and highly purity level.

The new MBE49 machine will be installed in a brand new LLC Connector Optics facility in St Petersburg.

"We were impressed by the performance of the Riber MBE machines and by the quality of the optical device structures obtained using the MBE49. The reputation of RIBER and the total installed base of RIBER production machines around the world illustrate its foremost expertise in the nanotechnology industry and confirm its internationally recognized reputation in ultra-vacuum deposit technologies", stated Leonid Karachinsky, Chief Executive Officer of Connector Optics.

More than 180 production systems have been installed worldwide and are dedicated to optical components design and to the mass production of radiofrequency components.

About LLC CONNECTOR OPTICS:

Connector Optics LLC was established in 2009 in St Petersburg and specializes in the production of optical components for ultra-high speed data transmission via optical fiber networks. Connector Optics currently owns the intellectual property rights and the necessary expertise for the production of a range of 850/980 nm ultrahigh speed (up to 40 Gbps) vertical-cavity surface-emitting lasers (VCSELs) and photodetectors.
