“…We used various wavelengths of picosecond lasers to examine the different electric field distributions at various depths of the device. The device exhibited the largest jitter value when subjected to the 405nm wavelength, commonly used in FLIM applications [43,44], and the 905nm wavelength, commonly used in automotive Lidar applications [45,46], also showed a significantly larger jitter value compared to the 780nm wavelength, commonly used in pulsed Lidar imaging and high spectral resolution Lidar applications [47,48,49], as shown in Figure 7(b).…”

We have proposed a structural design for a single photon avalanche diode with a low breakdown voltage. This diode is fabricated using Taiwan Semiconductor Manufacturing Company (TSMC) 0.18 µm HV CMOS technology, and it can maintain a high operating excess voltage in an n-on-p design without requiring any additional customized well layers. The n-on-p type device is particularly advantageous for a 3D-stacked backside illuminated structure and offers excellent photon detection capabilities at longer wavelengths. By incorporating a high doping concentration PDD well layer, we can significantly increase the excess bias, resulting in enhanced photon detection probability in the near-infrared wavelength range, all while maintaining a lower voltage due to a reduction in breakdown voltage. This design also leads to power consumption savings. As a result, our designed device is well-suited for consumer applications such as 3D image rendering and Lidar technology.
