Abstract :
The radiation hardness of double-sided silicon strip detectors (DSSD) has been tested. It was found that addressing charge-up effects of silicon dioxide is a key point in making radiation-hardened DSSD. In order to study this effect, a dedicated test using MOS gate isolated DSSD was made. Implantation of a thicker (denser) acceptor dopant layer in the P region and utilizing the resistance of poly-silicon as a bias voltage supply have been proposed to prevent this effect. Utilizing this method, the authors have produced radiation-hardened devices, made a test exposure, and found that the prevention measures work very well.<>
