摘要： A method of forming a semiconductor package (32) includes etching a conductive sheet (10) to form a first interconnection system (12). An integrated circuit (IC) die (22) is placed on and electrically connected to the first interconnection system (12). Next, a molding operation is performed to encapsulate the IC die (22), the electrical connections (24, 26) and at least a portion of the first interconnection system (12). A portion (20) of the conductive sheet (10) is then removed to expose a surface (30) of the first interconnection system (12). A second interconnection system (34) then is formed over the exposed surface (30) of the first interconnection system (12).

摘要： A method of manufacturing a semiconductor wafer for dicing includes providing a semiconductor wafer including a substrate and a plurality of upper layers on the substrate that form a formation of die areas. The formation is arranged so that adjacent die areas are separated by a path for a dicing tool. Within each path, a pair of spaced apart lines is fabricated. Each line defines a dicing edge of a respective path and has at least one trench extending between a top surface of the wafer and the substrate. Each trench is filled with a stress absorbing material for reducing die tool induced stress on the die areas during dicing.

摘要： A flip-chip bump carrier type package is formed by providing a sheet of metal foil and forming cavities in a first surface of the sheet. The cavities are plated with a conductive metal to form external interconnects. An insulating film is formed over the metal foil first surface and the plated cavities and then vias are formed in the insulating film. The vias contact respective ones of the plated cavities. The vias are then plated and a solder resist film is formed over the insulating film and the plated vias. The solder resist film is processed to form exposed areas above the vias, which areas are then plated with a conductive metal. A bumped semiconductor die is attached to the first surface of the metal foil, where the die bumps contact respective ones of the plated, exposed areas, which electrically connects the die to the plated cavities. Finally, the sheet of metal foil is removed so that outer surfaces of the plated cavities are exposed. As stated above, the plated cavity outer surfaces form electrical interconnects between the die and a printed wiring board.

摘要： A method of packaging semiconductor integrated circuits, including the steps of providing a transfer film and forming a patterned, conductive layer on a surface of the transfer film. A first semiconductor integrated circuit (IC) then is attached to the transfer film, where an active side of the first IC is attached to the transfer film. A second semiconductor IC then is attached to the first IC, where a bottom side of the second IC is attached to a bottom side of the first IC. Die pads on an active surface of the second IC are electrically connected to the conductive layer with wires and then a resin material is provided on one side of the transfer film to encapsulate the first and second ICs, the wires and a portion of the conductive layer. Next the transfer film is removed, which exposes the active side of the first IC and the conductive layer. An electrical distribution layer is formed over the active side of the first IC and the conductive layer and conductive balls are attached to the electrical distribution layer. The conductive balls allow electrical interconnection to the first and second integrated circuits.
