The 3D IC includes a first IC die comprising a first semiconductor substrate, and a first interconnect structure over the first semiconductor substrate. The 3D IC also includes a second IC die comprising a second semiconductor substrate, and a second interconnect structure that separates the second semiconductor substrate from the first interconnect structure. A seal ring structure separates the first interconnect structure from the second interconnect structure and perimetrically surrounds a gas reservoir between the first IC die and second IC die. The seal ring structure includes a sidewall gas-vent opening structure configured to allow gas to pass between the gas reservoir and an ambient environment surrounding the 3D IC.
