Science and technology are increasingly advancing, and people's level of observation of things is getting deeper and deeper. The product we bring today is an optical chip substrate used on single-photon avalanche diode (SPAD) imaging detectors. Single-photon avalanche diodes (SPADs) play an important role in many fields, including but not limited to astronomy, flow cytometry, fluorescence lifetime imaging microscopy (FLIM), particle sizing, quantum computing, quantum key distribution, and single-molecule detection.
The most challenging part of the product's process is the two-step staircase in the picture on the top, which requires two controlled-depth routings and laser opening. The requirements for controlling the depth are very strict.
