Methods for fabricating photoimagers, such as complementary metal-oxide-semiconductor (CMOS) imagers, include fabricating image sensing elements, transistors, and other low-elevation features on an active surface of a fabrication substrate, and fabricating contact plugs, conductive lines, external contacts, and other higher-elevation features on the back side of the fabrication substrate. Imagers with image sensing elements and transistors on the active surface and contact plugs that extend through the substrate are also disclosed, as are electronic devices including such imagers.
