Riber operates in a specific domain: we are experts in Molecular Beam Epitaxy (MBE), a technique which is used to grow compound semiconductors, and we provide Innovative Solutions for Semiconductor Industry.
Compound semiconductors are all around us: III-V, II-VI, nitrides, advanced oxides and others, generate true revolutions in several industrial and consumer fields like micro- and power electronics, lasers, detectors, solar or displays.
Boosted by the Internet of Things and cloud’s use, they are extensively used in datacenters, to process information at the speed of light, with photonics devices.
Also in the photonics field, medical applications benefit from the rise of compound semiconductors : medical sensing or fine surgery experience innovative practices with newly available lasers, such as in the industry, where they are core components for metal cutting machines.
Widely used in defense and security applications, for communications, optical detectors, gas sensing, and tomorrow, quantum computing, the future of compound semiconductors is promising, not only for industrial fields.
Step by step, they are also changing our everyday life: embedded in our smart vehicles, with LIDAR sensors, in our screens, with high efficiency microLEDs or virtual reality devices, or in our smartphones. They make 3D sensing and face recognition possible, thanks to new VCSELs generation, they push broadband communication towards 5G and 6G thanks to high speed radiofrequency (RF) components.

To ensure efficient answers to customers all around the world, Riber provides support from its headquarters in France and additional offices in the USA and Asia.
Riber’s development of MBE systems can be traced back to 1976, twelve years after the company was founded, when its expertise in state-of-the-art, ultra-high vacuum equipment helped academic pioneers to build the first-ever MBE deposition systems. Riber quickly grasped the tremendous potential that these growth tools had for revolutionizing the production of optoelectronic and electronic devices. Within two years, it had launched the world’s first ‘turnkey’ MBE system, in partnership with Professor and future Nobel Prize Al Cho, who demonstrated the need for a high purity growth technique to create AlGasAs high electron mobility transistors (HEMT).
Following on from this milestone in 1978, Riber developed and refined many key technologies for improving MBE reactor performance. The product portfolio blossomed from the MBE 2300 to the Compact and Epineat series, and in the 1990s Riber launched the world’s first high-throughput production reactor, the MBE 49 followed in the early 2000s by the biggest mass production systems MBE 6000/7000.
In addition, it has diversified its product range, with the acquisition of the French components manufacturer Addon in 2004 (RF plasma sources, valved cells for corrosive materials, cells for solar & OLEDS applications).
In 2008, Riber strengthened its leading position by acquiring MBE systems manufacturer VG Semicon and keeps on servicing and upgrading VG reactors all around the world until now.
Riber launched MPVD300 in 2009, a thin-film, SEMI-compatible, evaporation system which enables to manufacture next-generation silicon chips.
In 2010, Riber has started to address one of the biggest problems facing manufacturers of copper indium gallium (di)selenide (CIGS) thin-film solar cells: a high-growth rate, precisely controlled selenium source. Riber also developed dedicated effusion cells integrated in the production lines of OLED manufacturing plants.
Riber continuously improved and developed its portfolio the following years, with the birth of MBE412 in 2011 (designed from the acclaimed Epineat platform), then its research flagship reactor Compact 21 DZ (2013), the acquisition of MBE Control Solutions in the USA (2015).
The past 2 years have seen the installation of a production MBE 49 reactor, dedicated to GaN growth (2018), in collaboration with the CRHEA research center (France), the introduction the introduction of the MBE8000 “super-reactor”, enabling to grow up to 6 x 8’’ wafers simultaneously, specially designed to obtain the highest performance VCSELs lasers (2020) or the launch of in situ curvature instrumentation EZ-CURVE, to further move towards Smart MBE (2020).
