A stacked semiconductor device having hybrid metallic structures and associated systems and methods are disclosed herein. The stacked semiconductor device can include a first semiconductor die and a second semiconductor die. The first semiconductor die can include a top surface, a first bond site at the top surface and a second bond site at the first surface spaced apart from the first bond site. The second semiconductor die can include a lower surface facing the top surface of the first semiconductor die, a third bond site at the lower surface, and a fourth bond site at the lower surface. The third bond site includes a conductive structure bonded to the first bond site by a metal-metal bond. The fourth bond site at the lower surface includes a solder ball bonded to the second bond site.

Hybrid metallic structures in stacked semiconductor devices and associated systems and methods

Semiconductor devices including one or more interfacing segments patterned within an outer protective layer and associated systems and methods are disclosed herein. The one or more interfacing segments may provide attachment interfaces/surfaces for connection pads. The one or more interfacing segments or a portion thereof may remain uncovered or exposed and provide warpage control for the corresponding semiconductor device.
