Silicon Photomultipliers (SiPM) has become more and more important in many fields. In practical applications, its surface needs to be covered with passivation protective layer and anti-reflection coating. The usual practice is to cover the protective layer on the anti-reflection coating. However, the upper protective layer will change the anti-reflection effect. We studied the effect of SiPM surface coverage protective material on its light response characteristics. The simulation result showed that when the surface of SiPM device has SiO2 anti-reflection coating and silicon resin protective layer, the reflection light can be reduced by 27% and the photocurrent can be increased by 20% in the visible and near-infrared wavelength range. When the wavelength of light is 905 nm and the thickness of silicon resin changes in the range of 100 ~ 300 microns, the surface light reflectivity of the device can be reduced from 33% of bare silicon to 5.8% ~ 8.9%. Finally, the transmission spectrum of the double-layer medium composed of a glass slide with a main component of a SiO₂ slice and a silicon resin coating was tested. The experimental results showed that the light transmittance of the double-layer coating system in the visible region increased by about 20% after the addition of silicon resin. The experimental results are basically consistent with the simulation results. This shows that the SiPM surface protective coating layer can effectively reduce the reflected light on the surface of the device and further achieve the effect of anti-reflection.
