Structured glass articles include a glass substrate including a glass cladding layer fused to a glass core layer, a cavity formed in the glass substrate, and a shielding layer disposed within the cavity. In some embodiments, a passivation layer is disposed within the cavity such that the shielding layer is between the passivation layer and the glass substrate. A method for forming a glass fan-out includes depositing a shielding layer within a cavity in a glass substrate. The glass substrate includes a glass cladding layer fused to a glass core layer. A silicon chip may be deposited within the cavity. In some embodiments, the method also includes depositing a passivation layer within the cavity such that the shielding layer is between the passivation layer and the glass substrate.
