Abstract
A structure for a detector with a high spatial resolution is characterized not only as integrating on the same chip both PIN diodes and readout circuitry for detecting the charge collected through the individual diodes, but places the junction and collection electrode on opposite ends of the PIN diode. This reduces the fields at the collection electrode, and allows the wells containing the readout circuitry, which should be located as close to the collection electrode as possible to minimize collection electrode capacitance, to be placed in a low field region. The bias voltage required on the wells can then be reduced, and the electrodes for collecting the generated charge can be made smaller.
