  • Patent number: 5530278
    Abstract: In dicing of semiconductor chips from a wafer and mounting of the chips in an apparatus, techniques ensure the integrity of bonding pads and wire bonds in the dicing of individual chips and the connection of wire bonds to the chips. The wire bonds in the undiced chips are each connected to a probe pad disposed in an inter-chip area on the wafer, and this probe pad is used to accept probe pins which may otherwise damage the bonding pads on the chips themselves. In the dicing step, the probe pads are obliterated by the cutting blade. A polyimide dam disposes adjacent the bonding pads restricts the migration of liquid encapsulant securing the wire bonds to the bonding pads.
