Abstract: A semiconductor device is provided that includes a frontside and a backside, four sidewalls, a first solder/glue connection on the frontside and a second solder/glue connection on the backside. The semiconductor device is either connected as a chip scale package to a printed circuit board or inside a semiconductor package via one of the four sidewalls, so that the first solder/glue connection and the second solder/glue connection are visible for a visual solder/glue inspection.

Abstract: A semiconductor device is provided that includes a substrate, a pocket within the substrate, a solderable/glueable re-distribution layer arranged in the pocket and a die. The die is arranged downwards, so that a base contact and an emitter contact of the die face the bottom of the device, and a collector contact of the die faces the top of the device. The solderable/glueable re-distribution layer includes a first and second re-distribution layer part and the first re-distribution layer part and the second re-distribution layer part are isolated from each other by an isolating material. The emitter contact is connected to the first re-distribution layer part and the base contact is connected to the second re-distribution layer part. The emitter contacts via the first re-distribution layer part, the base contacts via the second re-distribution layer part, and the collector contact are fan out to the top surface of the semiconductor device.
