In this work, n+pn-type photodiodes with various surface n + layer profiles formed on the atomically flat Si surface were evaluated to investigate the relationships between the surface photo-generated carrier drift layer dopant profiles with a high uniformity and sensitivity and stability to UV-light. The degradation mechanism of photodiode sensitivitiy in UVlight wavelength due to UV-light exposure is explained by the changes in the fixed charges and the interface states at Si/SiO2 system above photodiode. Finally, a design strategy of photodiode dopant profile to achieve a high sensitivity and a high stability to UV-light is proposed.
