Abstract
A structure for a focal plane array substrate is disclosed that includes a focal plane array positioned above a semiconductor substrate containing a signal processor. The signal processor is connected to the image detection elements of the focal plane array by connections through the focal plane array chip itself. A method for interconnecting an image array to a signal processor located beneath the image array is also disclosed. This method includes forming holes in the imager array and forming buses connecting the imager array elements to conductors located in the holes that extend to bonding pads connected to the signal processor located below.
