Depending on your needs, a reduced-functionality free version may be available. Conclusion
Advances in fabrication techniques and material science are crucial for improving SPAD performance. Techniques such as using different materials (e.g., silicon, InGaAs), optimizing the device structure, and improving passivation techniques are areas of ongoing research. spad next crack free
Even if a SPAD survives fabrication without cracks, prolonged operation can induce new cracks or propagate existing ones. SPADs are often operated at high bias voltages and can be subjected to significant self‑heating, especially in arrays where many pixels fire frequently. This heating leads to thermal expansion, and repeated heating and cooling cycles – known as – are a classic driver of fatigue cracking. Depending on your needs
