STRENGTHENED WIRE-BOND
An electrical circuit in a semiconductor package may include a wire connected at each end by a bond point formed using a wire-bonding machine. When a connection point (e.g., a die pad) has a very small dimension, the wire used for the circuit may be required to have a similarly small diameter. This small diameter can lead to a weak bond point, especially in bonds that include a heel portion. The heel portion is a transition region of the bond point that may have less strength (e.g., as measure by a pull-test) than other portions of the bond point and/or may be exposed to more forces than other portions of the bond point. Accordingly, a capping-bond point may be applied to the bond point to strengthen the bond point by clamping the heel portion and shielding it from forces that could cause cracks.

A bonding wire for connecting a first pad to a second pad is provided. The bonding wire includes a ball part bonded to the first pad, a neck part formed on the ball part, and a wire part extending from the neck part to the second pad. Less than an entire portion of a top surface of the neck part is covered by the wire part, and the wire part is in contact with the neck part, the ball part, and the first pad.

The conductive wire electrically connects the first pad and the second pad. The third pad is disposed between the first pad and the second pad. The conductive wire has a portion located on the third pad.
Segmented shielding using wirebonds
The present disclosure relates to segmented shielding using wirebonds. In an exemplary aspect, a shield is formed from a series of wires (e.g., wirebonds) to create a wall and/or shielded compartment in an integrated circuit (IC) module. The wires can be located in any area within the IC module. The IC module may be overmolded with an insulating mold compound, and a top surface of the insulating mold can be ground or otherwise removed to expose ends of the wires to a shield layer which surrounds the insulating mold. Some examples may further laser ablate or otherwise form cavities around the ends of the wires to create stronger bonding between the wires of the shield and the shield layer.
