Abstract
In an embodiment, a package includes a first package structure including a first die having a first active side and a first back-side, the first active side including a first bond pad and a first insulating layer a second die bonded to the first die, the second die having a second active side and a second back-side, the second active side including a second bond pad and a second insulating layer, the second active side of the second die facing the first active side of the first die, the second insulating layer being bonded to the first insulating layer through dielectric-to-dielectric bonds, and a conductive bonding material bonded to the first bond pad and the second bond pad, the conductive bonding material having a reflow temperature lower than reflow temperatures of the first and second bond pads.
