Abstract:
Semiconductor devices (10) comprising at least one electrically conductive metal element (16) in a nonconductive package material (20) are manufactured by: - providing a first metal layer (102) having a smooth morphology for covering the aforesaid metal element (16); and - providing a second metal layer (104) for covering partially the first layer (102), leaving at least one portion of the surface of the first layer (102) exposed, the second layer (104) having a rough morphology. There may moreover be provided a die pad (14) for mounting a semiconductor die (12) by providing the aforesaid first layer (102) for covering the die pad (14) and attaching a semiconductor die (12) on the die pad (14) in contact with said first layer (102).
