METHOD OF MANUFACTURING SEMICONDUCTOR DEVICES AND CORRESPONDING SEMICONDUCTOR DEVICE
A semiconductor chip is arranged over a substrate in the form of a leadframe. A set of current-carrying formations configured as conductive ribbons are coupled to the semiconductor chip. The substrate does not include electrically conductive formations for electrically coupling the conductive ribbons to each other. Electrical contacts are formed via wedge bonding, for instance, between adjacent ones of the conductive ribbons so that a contact is provided between the adjacent ones of the conductive ribbons in support of a multi-formation current-carrying channel.

Semiconductor package design for solder joint reliability
Embodiments described herein provide techniques for using a stress absorption material to improve solder joint reliability in semiconductor packages and packaged systems. One technique produces a semiconductor package that includes a die on a substrate, where the die has a first surface, a second surface opposite the first surface, and a sidewall surface coupling the first surface to the second surface. The semiconductor package further includes a stress absorption material contacting the sidewall surface of the die and a molding compound separated from the sidewall surface of the die by the stress absorption material. The Young's modulus of the stress absorption material is lower than the Young's modulus of the molding compound. One example of a stress absorption material is a photoresist.
