Abstract
An infrared (IR) imaging device includes substantially identical top and bottom IR detector arrays. In separate embodiments, either a top or bottom surface of the top array is stacked onto the bottom array to confront a top surface of the bottom array and so that individual detector elements and subarrays of the top array are aligned with corresponding detector elements and subarrays of the bottom array. The image readout circuits of both the top and bottom array are connected by wire bonding to readout control circuits formed in the peripheral region of the wafer in which the bottom array is formed.
