Ultraviolet phototransistors were fabricated using Mg-doped ZnO film to achieve high mobility, a fast on–off transition, and high responsivity under deep UV illumination. Samco PECVD equipment PD-220NA was used for 200 nm thick SiO2 film deposition as a dielectric layer.

Samco offers high-speed SiO2 and SiNx film deposition technologies for various device applications. Also, we provide low-temperature PECVD (under 80°C) for device fabrication using heat-sensitive materials.
