Abstract
A semiconductor package and a method of forming the same are provided. The semiconductor package includes a package substrate and a semiconductor device mounted on the surface of the package substrate. A first ring is disposed over the surface of the package substrate and surrounds the semiconductor device. A second ring is disposed over the top surface of the first ring. Also, a protruding part and a matching recessed part are formed on the top surface of the first ring and the bottom surface of the second ring, respectively. The protruding part extends into and engages with the recessed part to connect the first ring and the second ring. An adhesive layer is disposed between the surface of the package substrate and the bottom surface of the first ring for attaching the first ring and the overlying second ring to the package substrate.
