WebDec 25, 2024 · A BSI silicon SPAD with a charge-focusing electric field was fabricated and characterized. The device operates with a CMOS readout circuit and achieves a PDE of 27% at 905 nm, low noise, and 240 ps timing resolution. Due to the charge focusing functionality, the detector has the potential to be scaled without significant loss of … WebAug 1, 2024 · One can observe that for the small implant, the avalanche breakdown probability is positive for lower applied voltages. This behavior is consistent with the behavior of so-called “charge focusing SPAD”, where the diameter of the heavy doped implant is reduced to obtain small breakdown voltage and higher PDE [13].

WebDec 16, 2024 · The newly developed SPAD sensor utilizes a proprietary pixel architecture that reflects photons inside the pixel in order to effectively detect photons across the entire range of the effective pixels. Under equivalent light, this SPAD sensor can capture the same images as a conventional CMOS sensor while requiring only 1/10 of imaging area. WebFeb 25, 2024 · Next, we propose a new-generation SPAD structure: charge focusing SPAD. The proposed concept is promising for overcoming a fundamental tradeoff between photon detection efficiency (PDE) and dark count rate (DCR), while suppressing correlated noise, hot pixel population, and power consumption.
