    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 method of making a reinforced semiconductor package includes forming a semiconductor interconnect tablet (24). Formation of the tablet includes providing a plurality of conductive metal tabs (10), positioning a first end (12) of the tabs (10) in a first section of a mold chase (14), positioning a second section of the mold chase (16) over a second end (18) of the tabs (10), such that the tabs (10) are anchored between the first and second sections (14, 16) of the mold chase, loading the first and second sections (14, 16) of the mold chase into a molding system (20) and performing a molding operation such that a plastic mold compound (22) is formed around the metal tabs (10) and an interconnect tablet (24) is formed. Then the first and second sections (14, 16) of the mold chase are removed from the molding system (20) and the interconnect tablet (24) is removed from the first and second sections (14, 16) of the mold chase.

    摘要: A method of packaging a pressure sensor die includes providing a lead frame having a die pad and lead fingers that surround the die pad. A tape is attached to a first side of the lead frame. A pressure sensor die is attached to the die pad on a second side of the lead frame and bond pads of the die are connected to the lead fingers. An encapsulant is dispensed onto the second side of the lead frame and covers the lead fingers and the electrical connections thereto. A gel is dispensed onto a top surface of the die and covers the die bond pads and the electrical connections thereto. A lid is attached to the lead frame and covers the die and the gel, and sides of the lid penetrate the encapsulant.
