Abstract
A hybridized image sensor includes a first die and a second die. The first die includes a first surface, a first plurality of conductive bumps fabricated on the first surface, and a first alignment feature fabricated on the first surface. The second die includes a second surface, a second plurality of conductive bumps fabricated on the second surface, and second alignment features fabricated on the second surface, wherein the first alignment features interact with the second alignment features to align the first plurality of conductive bumps with the second plurality of conductive bumps.
