what is active edge sensor how its mechanised

The active edge technology allows to reduce the insensitive area at the border of the sensor its mechanism is ion etched trench which avoids the crystal damage produced by the standard mechanical dicing process.

Thin planar n-on-p pixel sensors with active edge have been designed and produced by LPNHE and FBK foundry. Two detector module prototypes, consisting of pixel sensors connected to FE-I4B readout chips, have been tested with beams at CERN and DESY. In this paper the performance of these modules are reported. In particular the lateral extension of the detection volume, beyond the pixel region, is investigated and the results show high hit efficiency also at the detector edge, even in presence of guard rings.

Active Edge is included in google pixel phone for the first time in mobiles. Previously it was in other appliances. etc..ACs
