Abstract :
A new high voltage diode termination structure has been developed for the backside junction of silicon detectors which require double-sided processing. The new structure consists of a deep vertical etch through the diode at the edge of the detector. It requires only one mask, and is extremely robust to scratches or other mechanical damage. The vertical termination has been successfully applied to an integrated pixel detector, where it increased yield. It has also been applied to an 8mm diameter cylindrical drift detector
