Semiconductor devices having recessed edges with plated structures, semiconductor assemblies formed therefrom, and associated systems and methods are disclosed herein. In one embodiment, a semiconductor assembly includes a first semiconductor device and a second semiconductor device. The first semiconductor device can include an upper surface and a first dielectric layer over the upper surface, the second semiconductor device can include a lower surface and a second dielectric layer over the lower surface, and the first and second dielectric layers can be bonded to couple the first and second semiconductor devices. The first and second dielectric layers can each include a plurality of inwardly extending recesses exposing a plurality of metal structures on the respective upper and lower surfaces, and the upper surface recesses and metal structures can correspond to the lower surface recesses and metal structures. The metal structures can be electrically coupled by plated structures positioned in the recesses.
