A semiconductor device includes a circuit board including an insulating layer having opposite front and rear surfaces, an electrode pad disposed on the front surface, a housing having an installation area for the circuit board, and a bonding material embedded in a recess within either a first area located at the rear surface of the insulating layer directly below an area of the circuit board in which the electrode pad is disposed, or at a second area located within the installation area of the housing and corresponding to the first area in a plan view.

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.
