Riber and Comptek sign commercial partnership


Collaboration will support and accelerate the transfer of Comptek's Kontrox passivation process technology to industrial clients

Riber, a semiconductor equipment company, and Comptek Solutions, which is involved in III-V compound semiconductor quantum surface engineering, have signed a commercial partnership deal to develop joint technological solutions.

Founded in 2017, Comptek Solutions is a Finnish company that addresses the oxidation issue in III-V compound semiconductors with its Kontrox a patented passivation process.

Compound semiconductor devices have a natural tendency to oxidise almost instantly once exposed to air, which results in the formation of an amorphous oxide layer leading to a range of defects that limit their performance and manufacturing yields.

Kontrox creates a thin layer of stable crystalline oxide with a dry vacuum approach, preventing the amorphous oxidation layer from forming. Compared to existing methods, Kontrox reduces the density of interface defects and delivers increased efficiency and higher manufacturing yields for III-V compound semiconductor devices such as P-HEMTs and HBTs for 5G.

The technology also boosts the performance of optoelectronic devices - such as mini- and micro LEDs, high-power lasers, VCSELs and infrared sensors, improving the efficiency, brightness, and lifespan.

In addition, Kontrox can be used in next-generation CMOS processors.

Partnership’s objective

The partnership between Riber and Comptek Solutions aims to build a long-term collaboration to support and accelerate Kontrox technology transfer to industrial clients by delivering customised, highly efficient ultra-high vacuum equipment along with expert technical support and lifecycle management services.

This collaboration makes it possible to customise and optimize the specifications for equipment to deploy Kontrox technology according to user needs. This will enhance the technology industrialisation featuring a process control developed specifically for Kontrox.
