SPAD Technology

SPAD (Single-Photon Avalanche Diode) is a key component in single-photon sensing technology, widely applied in LiDAR systems and photon-counting SPAD cameras. SPAD enables precise detection of weak photon signals at the single-photon level, essential for LiDAR systems. It emits laser pulses and measures reflected signals to obtain distance and 3D spatial data. Manufactured using CMOS processes, SPAD offers benefits such as low cost, mass production, and higher integration, making it ideal for LiDAR system commercialization. It is expected to be widely used in autonomous vehicles, augmented reality (AR), 3D sensing, and more.

SPAD Device Development for Various Applications

We specialize in designing individual SPADs and arrays, characterizing and analyzing SPADs, and enhancing their performance. SPAD development in standard CMOS processes is complex and held by only a few global companies. Leveraging advanced research and specialized knowledge from KIST, we aim to drive successful commercialization. We utilize various process options (thick Epi, Full DTI, trench guide, ulens, BSI, etc.) to enhance performance metrics like photon detection efficiency, dark count, dead time, and low jitter, meeting the demands of diverse industries.
