Semiconductor Detector Device

摘要

A semiconductor detector device comprises a layer of semiconductor material for generating charge in response to an input event and an array of pixels for collecting charge. Tracks are connected to the pixels to supply signals representing the collected charge to a reader circuit. The pixels are grouped into sets, all the pixels within a set being connected to the same track, the sets of pixels being interwoven so that so that any group of n adjacent pixels capable of collecting charge generated by a single input event is connected to a combination of n tracks that is unique to the group of pixels, where n has a value of one of 2, 3 or 4. This allows detection of position of the area of charge collection on the basis of temporally coincident signals on a combination of at least n tracks.

1. A semiconductor detector device comprising:
a layer of semiconductor material for generating charge in response to an input event; an array of pixels formed in the layer of semiconductor material for collecting charge generated in the layer of semiconductor material, the pixels being spatially distributed in two dimensions; tracks connected to the pixels to supply signals from the pixels representing the collected charge to a reader circuit, wherein the pixels of the array are grouped into sets of pixels, all the pixels within a set being connected to the same track, the sets of pixels being interwoven so that any group of n adjacent pixels capable collecting charge generated by a single input event is connected to a combination of n tracks that is unique to the group of pixels, where n has a value of one of 2, 3 or 4.
