摘要： A semiconductor package system comprises a semiconductor package and a cap. The semiconductor package comprises a die pad, a chip mounted or arranged to a first main face of the die pad and an encapsulation body encapsulating the chip and the die pad. The cap covers at least partly an exposed second main face of the die pad. The cap comprises a cap body of an electrically insulating and thermally conductive material and a fastening system fastening the cap to the semiconductor package. The fastening system extends from the cap body towards the encapsulation body or along a side surface of the semiconductor package.

摘要： A method includes providing a joining material between a surface of a component and a surface of an electronic component. A plurality of spacer elements is embedded in the joining material. The spacer elements are coated with a coating material. The coating material includes sinter particles. A dimension of the sinter particles is greater than 1 nanometer and smaller than 1000 nanometers. The method further includes forming interconnects from the coating material. The interconnects are arranged between the spacer elements and the surface of the component, and between the spacer elements and the surface of the electronic component.

摘要： A semiconductor device includes: a carrier having a die pad and a contact; a semiconductor die having opposing first and second main sides and being attached to the die pad by a first solder joint such that the second main side faces the die pad; and a contact clip having a first contact region and a second contact region. The first contact is attached to the first main side by a second solder joint. The second contact region is attached to the contact by a third solder joint. The first contact region has a convex shape facing towards the first main side such that a distance between the first main side and the first contact region increases from a base of the convex shape towards an edge of the first contact region. The base runs along a line that is substantially perpendicular to a longitudinal axis of the contact clip.
