Conductive coatings
ALD coatings solve many challenges of creating high-quality conformal conductive coatings for complex surfaces. The ability to reliably deposit thin conductive coatings and resistive layers enables new electronics solutions and improves the performance and durability of electronic devices, such as LEDs and OLEDs. Beneq has also used Aluminum doped Zinc Oxide (AZO) TCO coating by ALD as an alternative for the sputtered ITO.
