Abstract: Packages for an integrated circuit device and methods and leadframes for making such packages are disclosed. The package includes a die, a die pad, leads, bond wires, and an encapsulant. The lower surfaces of the die pad and leads are provided with a stepped profile by an etching step that etches partially through the thickness of a peripheral portion of the die pad, and also etches partially through the thickness of portions of the leads.

Other portions of the die pad and leads are exposed at the lower surface of the package for connecting the package externally. A metal leadframe for making an encapsulated package includes an outer frame. A die pad is within and connected to the frame. Leads extend from the frame toward the die pad without contacting the die pad. After an encapsulation step, the die pad and leads are severed from the leadframe, and a completed package is cut from the leadframe. A portion of the severed leads may extend laterally beyond the package sides, and may be bent upwards at an oblique angle to facilitate connection of a solder interconnection to the package. The package may be made one at a time, or a plurality of packages may be made simultaneously. Packages may be cut from the leadframe with a punch or saw.
