  • Publication number: 20240090130
    Abstract: A semiconductor device package may include a substrate having an insulating layer with a patterned conductive layer formed thereon, the patterned conductive layer including at least a first pattern portion and a second pattern portion. The semiconductor device package may include a leadframe having a lead that is soldered to the substrate with solder provided in an opening between the first pattern portion and the second pattern portion and with the lead inserted into the opening.

  • Publication number: 20230343739
    Abstract: A semiconductor device includes a die pad, a bond post, a die disposed over the die pad, a wire coupled between the die and the bond post and having a first portion bonded to the die at a first bond area and a second portion bonded to the bond post at a second bond area, a first bonding cover disposed over the first portion, and a second bonding cover disposed over the second portion. A method includes bonding a first portion of a wire to a die at a first bond area, bonding a second portion of the wire to a first bond post of a lead frame at a second bond area, applying a bonding material over the first bond area to form a first bonding cover, and applying the bonding material over the second bond area to form a second bonding cover.

  • Publication number: 20220020717
    Abstract: 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.
