Claims14
A method for simultaneously producing a multiplicity of surface-mountable semiconductor components each having at least one semiconductor chip, at least two external electrical connections, which are electrically conductively connected to at least two electrical contacts of the semiconductor chip, and an encapsulation material (50), wherein the method comprises:
- a) providing a film strip, which has on both sides electrically conductive layers that are patterned and through-connected through the film strip in such a way that an array comprising a multiplicity of component region arranged next to one another is formed, each of said component regions comprising structures of the electrically conductive layers for the at least two external electrical connections;
- b) applying at least one semiconductor chip on each of the component regions, and electrically connecting the semiconductor chip to the associated external electrical connections;
- c) introducing the array into an injection mold, in which a single cavity which spans all the semiconductor chips of the array and forms a void there essentially exclusively on the side of the semiconductor chips is provided for an array;
- d) injecting encapsulation material into the cavity;
- e) at least partially curing the encapsulation material and removing the array from the injection mold;
- and
- f) singulating the array into individual semiconductor components by means of severing the encapsulation material material and the film strip with the patterned electrically conductive layers between the component regions.
