Abstract
A high-resolution radiation detector cell array has a planar substrate, with multiple switching circuits, interposed between a detector substrate and a subsequent substrate containing high-sensitivity preamplifiers; each of the middle-substrate switching circuits operates to substantially continuously connect cyclic different ones of an assigned different set of the array cells to an associated single one of multiple preamplifiers. In a N.times.M array of cells used with a C column-by-R row switching subassembly, a total array of (N/C).times.(M/R) preamplifiers are needed. The generally-planar detector, switch and preamplifier substrates can be connected using metallic 'bump' contacts; the switch layer material may be selected to have a CTE between the CTEs of the detector and preamplifier layers.
