Abstract: Semiconductor devices and corresponding methods of manufacture are disclosed. The method includes forming a first device structure on a first substrate, a first laser liftoff layer on the first device structure, a protective layer on the first laser liftoff layer, and a second substrate on the protective layer. The method includes de-attaching, through applying radiation on the first laser liftoff layer, the protective layer from the first laser liftoff layer, with a first surface of the second substrate remaining in contact with a second surface of the protective layer. The protective layer is transparent to the radiation.

Abstract: At least one aspect of the present disclosure is directed to a semiconductor device. The semiconductor device includes a first substrate including a first area and a second area; a second substrate including a third area and a fourth area; a first bonding layer comprising a first dielectric material that bonds the first area to the third area; and a second bonding layer comprising a second dielectric material that bonds the second area to the fourth area. The first dielectric material is different from the second dielectric material.

Abstract: A method includes providing a first substrate having a first bonding surface. The method includes providing a second substrate having a second bonding surface. The method includes coupling a metal-containing precursor to the first bonding surface and the second bonding surface. The method includes activating the metal-containing precursor on the first bonding surface and the second bonding surface. The method further includes chemically reacting the activated metal-containing precursor on the first bonding surface and the second bonding surface to form an interface between the first substrate and the second substrate.
