Test Development Engineer

About the Company

Poro Technologies Ltd (Porotech), the Gallium Nitride (GaN) material technology developer, focuses on the development of high performance and energy efficient wide-bandgap compound GaN semiconductors. Its unique production process allows the controlled creation of a new class of nanostructured GaN semiconductor materials, called PoroGaNTM, engineered to deliver new materials properties and functionalities.

GaN is the silicon of the future, as it has many more interesting properties, including energy efficiency, than any other semiconductor materials. We can control the porosification process to vary the GaN nanostructures and hence engineer a wide range of material properties, such as optical, mechanical, thermal and electrical.

In conjunction with its partner and foundry network, Porotech is commercialising its PoroGaNTM semiconductor device solutions, offering an entirely new platform for MicroLED devices to be built upon and delivering transformative properties in a single, fully scalable step.

The technology is revolutionising the next-generation Micro-LED display industry by enabling all three (red, green and blue) pixel colours to be realised on a single InGaN materials system – an important world-first for mass market adoption.
