    Abstract: Seamless bonding layers in semiconductor packages and methods of forming the same are disclosed. In an embodiment, a method includes forming a second passivation layer over a first metal pad and a second metal pad, the first metal pad and the second metal pad being disposed over a first passivation layer of a first semiconductor die; depositing a first bonding material over the second passivation layer to form a first portion of a first bonding layer, wherein at least a portion of a seam in the first bonding layer is between the first metal pad and the second metal pad; thinning the first portion of the first bonding layer to create a first opening from the seam; and re-depositing the first bonding material to fill the first opening and to form a second portion of the first bonding layer.

    Abstract: A semiconductor device including a test pad contact and a method of manufacturing the semiconductor device are disclosed. In an embodiment, a semiconductor device may include a first metal feature and a second metal feature disposed in a single top metal layer over a substrate. A test pad may be formed over and electrically connected to the first metal feature. A first passivation layer may be formed over the second metal feature and the test pad and may cover top and side surfaces of the test pad. A first via may be formed penetrating the first passivation layer and contacting the test pad and a second via may be formed penetrating the first passivation layer and contacting the second metal feature.

    Abstract: A method includes bonding a tier-1 device die to a carrier, forming a first gap-filling region to encapsulate the tier-1 device die, forming a first redistribution structure over and electrically connected to the tier-1 device die, and bonding a tier-2 device die to the tier-1 device die. The tier-2 device die is over the tier-1 device die, and the tier-2 device die extends laterally beyond a corresponding edge of the tier-1 device die. The method further includes forming a second gap-filling region to encapsulate the tier-2 device die, removing the carrier, and forming a through-dielectric via penetrating through the first gap-filling region. The through-dielectric via is overlapped by, and is electrically connected to, the tier-2 device die. A second redistribution structure is formed, wherein the first redistribution structure and the second redistribution structure are on opposing sides of the tier-1 device die.

    Abstract: A semiconductor structure and the manufacturing method thereof are provided. A semiconductor structure includes a semiconductor substrate, a plurality of interconnecting layers, a first connector, and a second connector. The semiconductor substrate includes a plurality of semiconductor devices therein. The interconnecting layers are disposed over the semiconductor substrate and electrically coupled to the semiconductor devices. The first connector is disposed over the plurality of interconnecting layers and extends to be in contact with a first level of the plurality of interconnecting layers. The second connector is disposed over the plurality of interconnecting layers and substantially leveled with the first connector. The second connector extends further than the first connector to be in contact with a second level of the plurality of interconnecting layers between the first level of the plurality of interconnecting layers and the semiconductor substrate, and the first connector is wider than the second connector.
