Description

IMB-CNM has been a main actor in the development of Low Gain Avalanche Detectors since the initial device conception, more than a decade ago. In the last years, our efforts have been centred on developing new LGAD designs to enhance the device performance in aspects such as the charge collection efficiency or the improvement of the fill factor. At the same time, our technologies are being revisited to refine the fabrication yield, in particular for large pixelated array devices.
This contribution presents our latest advances and challenges in technologies such as trench-isolated inverse LGAD (TiLGAD), a promising design that looks for a 100% fill factor, for a wide range of low and high penetrating particles. In addition, we will show the first characterization of our deep-junction LGAD devices, a crucial step to stabilize the performance of the IMB-CNM pixel technologies.
