ABSTRACT:
A package for an integrated circuit is described, as are methods of making the package. The package includes a substrate having a generally planar first surface on which a metal die pad is formed. An integrated circuit die is attached to the metal die pad. An adhesive head surrounds the integrated circuit die and covers the exposed periphery of the metal die pad. A generally planar lid is in a press-fitted interconnection with the bead. An adhesive material covers conductive structures on the die, such as bonding pads, to prevent corrosion. Optionally, the package has vertical peripheral sides. The methods of making the package include methods for making packages individually, or making a plurality of packages simultaneously. Where a plurality of packages are made simultaneously, integrated circuit die are placed on each of a plurality of physically-joined package substrates on a generally planar sheet of substrate material. An adhesive bead is applied around each die. In cross-section, the bead has a central peak and a shorter peak on each side of the central peak. A sheet of lid material is placed onto the beads. After the bead is hardened, individual packages are formed by cutting the substrate sheet, lid sheet, and beads.
