In this paper, the reverse biasing and breakdown properties of the PureB diodes are investigated for different methods of processing the PureB anode window and the metal contacting. In particular, micron-sized devices are examined in order to assess their suitability for use in dense imaging arrays that may require operation as avalanche photodiodes to obtain the necessary photosensitivity [6]. For such small devices implanted guard rings cannot be implemented without paying a penalty in fill-factor. At the same time it is also desirable to position the photosensitive area away from the oxide perimeter where permanent damage can be inflicted by high reverse currents. Therefore, a “virtual” guard, using an n-enhancement implantation in the central region of the diode is applied here.
