Silicon Photomultiplier(SiPM)

Description：

Silicon photomultiplier (SiPM) is composed of avalanche photodiode arrays operating above the avalanche breakdown voltage and having an avalanche quenching mechanism in parallel. It has excellent photon number resolution and single-photon detection sensitivity. The silicon-based low-light detector has a very important and wide range of applications in particle physics and nuclear physics research, nuclear medicine diagnosis and treatment, lidar, fluorescence detection and other fields.

For a conventional SiPM, the quenching resistors are usually fabricated on the surface, and used to connect all APD cells to trace metal lines. In contrast, Our SiPM employs intrinsic epitaxial layer as the quenching resistors (EQR), and uses a continuous silicon cap layer as an anode to connect all the APD cells. As a result, the device has more compact structure and simpler fabrication technology, allows larger micro cell density (larger dynamic range) while retaining high photon detection efficiency (PDE).
