Abstract:
1. A monolithic sensor adapted for use in the detection of accelerated particles or high energy radiation, the sensor comprising a charge carrier transport layer, the charge carrier transport layer having dopants of a first conductivity type; at least one first well having dopants of the first conductivity type at a higher concentration than the charge carrier transport layer and having integrated therein readout circuitry; at least one second well having dopants of a second conductivity type forming a first junction with the charge carrier transport layer whereby when charge carriers are generated in the charge carrier transport layer, the charge carriers move towards and are collected at the junction between the charge carrier transport layer and the second well to generate a signal and wherein the sensor is capable of withstanding bombardment by accelerated particles or high energy radiation, wherein said charge carriers do not pass through a portion of said first well located closest to said second well, wherein said first well substantially surrounds said second well, and wherein said integrated readout circuitry in said first well provides readout of said signal, and wherein the first and second wells are formed in the charge carrier transport layer and the second well is isolated from the first well.
