Abstract:
A semiconductor chip is arranged on a first surface of a die pad in a substrate (leadframe) including an array of electrically conductive leads. An encapsulation of laser direct structuring (LDS) material encapsulates the substrate and the semiconductor chip. The encapsulation has a first surface, a second surface opposed to the first surface and a peripheral surface. The array of electrically conductive leads protrude from the peripheral surface with areas of the second surface of the encapsulation arranged between adjacent leads. LDS structured areas of the second surface located between adjacent leads in the array of electrically conductive leads provide a further array of electrically conductive leads exposed at the second surface. First and second electrically conductive vias extending through the encapsulation material as well as electrically conductive lines over the encapsulation material provide an electrical bonding pattern between the semiconductor chip and selected ones of the leads.
