Methods for manufacturing semiconductor devices having a flexible reinforcement structure, and associated systems and devices, are disclosed herein. In one embodiment, a method of manufacturing a semiconductor device includes electrically coupling at least one semiconductor die to a redistribution structure on a first carrier. The semiconductor die can include a first surface facing the redistribution structure and a second surface spaced apart from the redistribution structure. The method also includes reducing a thickness of the semiconductor die to no more than 10 μm. The method further includes coupling a flexible reinforcement structure to the second surface of the at least one semiconductor die.

To manufacture a redistribution layer for an integrated circuit, a first insulating layer is formed on a conductive interconnection layer of a wafer. A conductive body is then formed in electrical contact with the interconnection layer. The conductive body is then covered with an insulating region having an aperture that exposes a surface of the conductive body. The surface of the conductive body and the insulating region are then covered with an insulating protection layer having a thickness less than 100 nm. This insulating protection layer is configured to provide a protection against oxidation and/or corrosion of the conductive body.

Embodiments herein relate to systems, apparatuses, or processes for hybrid bonding two dies, where at least one of the dies has a top layer to be hybrid bonded includes one or more copper pad and a top oxide layer surrounding the one or more copper pad, with another layer beneath the oxide layer that includes carbon atoms. The top oxide layer and the other carbide layer beneath may form a combination gradient layer that goes from a top of the top layer that is primarily an oxide to a bottom of the other layer that is primarily a carbide. The top oxide layer may be performed by exposing the carbide layer to a plasma treatment. Other embodiments may be described and/or claimed.
