Embodiments disclose electronic packages with a die assembly and methods of forming such electronic packages. In an embodiment, a die assembly comprises a first die and a second die laterally adjacent to the first die. In an embodiment, the first die and the second die each comprise a first semiconductor layer, an insulator layer over the first semiconductor layer, and a second semiconductor layer over the insulator layer. In an embodiment, a cavity is disposed through the second semiconductor layer. In an embodiment, the die assembly further comprises a bridge substrate that electrically couples the first die to the second die, where the bridge is positioned in the cavity of the first die and the cavity of the second die.
