    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.
