Semiconductor device
A semiconductor device includes a semiconductor chip including a semiconductor substrate with a top surface electrode deposited on a top surface of the semiconductor substrate. An insulating film selectively covers edges of a top surface of the top surface electrode, and a plating layer covers the top surface of the top surface electrode exposed to an opening of the insulating film. A metal wiring plate includes a junction part located over the insulating film and the plating layer, and provided with a groove recessed upward from a bottom surface of the junction part. A solder part fills the groove so as to bond the plating layer and the bottom surface of the junction part together. A boundary between the insulating film and the plating layer is encompassed within the groove.
Stray inductance reduction in packaged semiconductor devices
In a general aspect, a semiconductor device can include a substrate and a positive power supply terminal electrically coupled with the substrate, the positive power supply terminal being arranged in a first plane.
