Abstract

The invention relates to a single event effect detecting device of an image sensor. The detecting device comprises an image processing module, a power source, a programmable power source and a test circuit board. The test circuit board is provided with an electronic imaging system and a sensor of an image to be tested. The image processing module can recognize white spots produced by bombardment of particles and count the number of the white spots and the size of occupied pixels, the transient effect on the pixels of the image sensor from single particles produced by the bombardment of the particles can be analyzed conveniently, and the single event effect sensibility of the image sensor can be effectively detected and evaluated. According to the single event effect detecting device, the single event effect produced in the particle irradiation process can be effectively and comprehensively detected, and the single event effect resisting performance index of a device can be effectively checked.

Description

technical field [0001] The invention belongs to the technical field of microelectronic device anti-single particle ability test verification, and relates to a single particle effect detection device of an image sensor. Background technique [0002] With the rapid development of semiconductor technology, the feature size and operating voltage of devices are getting smaller and smaller. Correspondingly, the critical charge is getting smaller and smaller, and the single event effect is becoming more and more obvious. In recent years, it has been found that the single event effect has a more significant impact on the working performance of the device, and its damage mode is becoming more and more complicated. If the reason for the functional interruption or functional error of the microelectronic device is not clear, it is impossible to correctly evaluate the radiation resistance of the microelectronic device. , in the later development of microelectronic devices, it is impossib...
