Abstract: A semiconductor chip or die is mounted at a position on a support substrate. A light-permeable laser direct structuring (LDS) material is then molded onto the semiconductor chip positioned on the support substrate. The semiconductor chip is visible through the LDS material. Laser beam energy is directed to selected spatial locations of the LDS material to structure in the LDS material a pat gstern of structured formations corresponding to the locations of conductive lines and vias for making electrical connection to the semiconductor chip. The spatial locations of the LDS material to which laser beam energy is directed are selected as a function of the position the semiconductor chip which is visible through the LDS material, thus countering undesired effects of positioning offset of the chip on the substrate.

Abstract: An encapsulation of laser direct structuring (LDS) material is molded onto first and second semiconductor dice. A die-to-die coupling formation between the first and second semiconductor dice includes die vias extending through the LDS material to reach the first and second semiconductor dice and a die-to-die line extending at a surface of the encapsulation between the die vias.

Metal material is electrolytically grown onto the locations of the encapsulation by exposure to an electrolyte carrying metal cations. The metal cations are reduced to metal material via a current flowing through the electrically conductive path provided via the electrode. The electrode is then disengaged from contact with the locations having metal material electrolytically grown thereon.

Each semiconductor die is provided with electrically-conductive protrusions (such as electroplated pillars or bumps) protruding from the semiconductor die opposite the substrate. Laser direct structuring material is molded onto the substrate to cover the semiconductor dice arranged thereon, with the molding operation leaving a distal end of the electrically-conductive protrusion to be optically detectable at the surface of the laser direct structuring material. Laser beam processing the laser direct structuring material is then performed with laser beam energy applied at positions of the surface of the laser direct structuring material which are located by using the electrically-conductive protrusions optically detectable at the surface of the laser direct structuring material as a spatial reference.

Abstract: A semiconductor chip is mounted at a first surface of a leadframe and an insulating encapsulation is formed onto the leadframe. An etching mask is applied to a second surface of the leadframe to cover locations of two adjacent rows of electrical contacts as well as a connecting bar between the two adjacent rows which electrically couples the electrical contacts. The second surface is then etched through the etching mask to remove leadframe material at the second surface and define the electrical contacts and connecting bar. The electrical contacts include a distal surface as well as flanks left uncovered by the insulating encapsulation. The etching mask is then removed and the electrical contacts and the connecting bars are used as electrodes in an electroplating of the distal surface and the flanks of the electrical contacts. The connecting bar is then removed from between the two adjacent rows during device singulation.
