Abstract

Ultraviolet (UV) sensitive Silicon based photodiodes integrated into a high-voltage modular 0.35 μm CMOS technology are presented. An optimized sensitivity higher than 0.1 A/W is obtained for the relevant UV-B (λ = 280-320 nm) and UV-A (λ = 320-380 nm) spectral range for n-on-p and p-on-n photodiodes. In addition, a special UV block layer can be integrated for dark current compensation without further mask count. The photodiodes are stable during long time UV light exposure.
