Abstract

The invention discloses a photoelectric detection sensor compatible with silicon bipolar process. The photoelectric detection sensor includes a first photoelectric detector and a second photoelectric detector; the first photoelectric detector comprises a first device region; the first device region of the first photoelectric detector is formed by the collector region of an NPN transistor; M second device regions of the first photoelectric detector are produced in the first device region of the first photoelectric detector, wherein M is a natural number smaller than 10; the second device regions of the first photoelectric detector are formed by the base region of the NPN transistor; the structure of the second photoelectric detector is identical to the structure of the first photoelectric detector; and the surface of the second photoelectric detector is coated with an aluminum film. The photoelectric detection sensor has the advantages of high quantum efficiency and high response speed.

Description

technical field [0001] The invention relates to a photoelectric detection sensor, in particular to a photoelectric detection sensor compatible with silicon bipolar technology. Background technique [0002] The basic function of the photodetection sensor is to convert the light power incident on the detector into the corresponding photocurrent. Its performance is directly related to the accuracy of the receiving processing circuit. Therefore, only the selection and design of a suitable photodetector will not weaken the performance of the receiving processing circuit. [0003] When designing, the main considerations are several technical indicators such as photodetector noise, quantum efficiency, and responsivity. [0004] In many application fields, such as the output part of the optocoupler, it is often necessary to integrate the photodetector and signal processing on the same single chip, that is, to realize the process compatibility between the photodetector and the sign...
