Claim:
1. A method comprising: providing a mold wafer having a plurality of modules, wherein each of the plurality of modules comprises a die with an input/output (I/O) port at a bottom surface of the die, wherein the die is adjacent to an inter-module area and partially encapsulated by a mold compound leaving the bottom surface of the die exposed; forming a first dielectric pattern over a bottom surface of the mold wafer, wherein the I/O port is exposed through the first dielectric pattern for each of the plurality of modules; forming a redistribution structure over the first dielectric pattern, wherein the redistribution structure comprises a shield connected element that is coupled to the I/O port and extends laterally from the I/O port into the inter-module area for each of the plurality of modules; forming a second dielectric pattern over the redistribution structure, wherein a bottom portion of the shield connected element is exposed through the second dielectric pattern for each of the plurality of modules; applying a bump contact to the exposed bottom portion of the shield connected element for each of the plurality of modules; sub-dicing the mold wafer at the inter-module area to create a cavity for each of the plurality of modules, wherein the cavity extends into the mold wafer from a top surface of the mold wafer without extending completely through the mold compound; removing a portion of the mold compound and a portion of the first dielectric pattern at a bottom of each cavity to form a channel that exposes a portion of the shield connected element for each of the plurality of modules; forming a shielding structure over the top surface of the mold wafer and exposed faces of the cavity for each of the plurality of modules, wherein the shielding structure is in contact with the shield connected element; and singulating the mold wafer at the inter-module area for each of the plurality of modules to form a plurality of shielded modules, wherein the shielding structure for each of the plurality of shielded modules remains in contact with the shield connected element.
