ABSTRACT:
A semiconductor chip (26) is attached to a leadframe (20, 30, 40). The leadframe (20, 30, 40) has an opening (24) or a cavity (34, 44) for receiving the semiconductor chip (26). The opening (24) or the cavity (34, 44) and the semiconductor chip (26) have corresponding shapes. The opening (24) or the cavity (34, 44) is made such that they are smaller than the size of the semiconductor chip (26) at room temperature. The opening (24) or the cavity (34, 44) is expanded and the semiconductor chip (26) is placed in the opening (24) or the cavity (34, 44). Subsequent to placing the semiconductor chip (26) in the opening (24) or the cavity (34, 44), the leadframe (20, 30, 40) is cooled so that an edge (25) of the leadframe grips a corresponding edge (29) of the semiconductor chip (26).
