Total Dose Effects on CMOS Active Pixel Sensors
نویسندگان
چکیده
Co irradiations have been carried out on test structures for the development of CMOS Active Pixel Sensors (APS) that can be used in a radiation environment. The basic mechanisms that may cause failure are presented. Ionization induced damage effects such as field leakage currents and dark current increase are discussed in detail. Two different approaches to overcome these problems are considered and their advantages and disadvantages are compared. Total dose results are presented on a pixel that can tolerate more than 200 kGy(Si) (20 Mrad(Si)) from a Co source.

A 512 512 CMOS active pixel sensor (APS) was designed and fabricated in a standard 0.5m technology. The radiation tolerance of the sensor has been evaluated with Co-60 and proton irradiation with proton energies ranging from 11.7 to 59 MeV. The most pronounced radiation effect is the increase of the dark current. However, the total ionizing dose-induced dark current increase is orders of magnit...
