Patent ID: 7569427

Claim:
A method for producing semiconductor components with connecting elements, the method comprising: producing semiconductor chip structures for discrete semiconductor components on the top side of a semiconductor wafer in semiconductor chip positions, which have contact areas; applying a separation film to the rear side of the semiconductor wafer; selective depositing mesa-type or mushroom-shaped connecting elements on the contact areas; selective applying an insulation layer to the top side of the semiconductor wafer whilst leaving free the top sides of the connecting elements; separating the semiconductor wafer into semiconductor chips on the separation film; applying an adhesive expandable packaging film to the insulation layer and the uncovered top sides of the connecting elements of the top side of the semiconductor wafer; removing the separation film from the rear side of the semiconductor wafer; expanding the packaging film with enlargement of the interspaces between the semiconductor chips; embedding the separated semiconductor wafer with connecting elements on the expanded packaging film into a plastics composition to form a composite plate with a coplanar area on the packaging film comprising top sides of the connecting elements and the plastic housing composition; removing the expanded packaging film; separating the composite plate into individual semiconductor components.
