Adding to our suite of passivation innovation is the Pilot Line Tool for substrates up to 200mm — an advanced R&D tool designed and installed by Comptek Solutions.

 

Tailored for power electronics and optoelectronic applications, it integrates Kontrox passivation technology with plasma-enhanced atomic layer deposition (ALD), supporting up to ten compound semiconductor wafers in an ISO5 cleanroom environment.

​

Funded by the EIC "Enlight" project, this tool is a successful showcase of Kontrox technology for larger substrates in an industrial setting. By combining Kontrox with ALD, it minimizes surface defects and creates a distinct III-V dielectric interface, elevating interface quality and compound semiconductor device performance to unprecedented levels.
