Abstract

Individual pieces of film adhesive ( 42 ) are placed on a support surface ( 46 ). Diced semiconductor chips ( 24 ) are individually placed on the individual pieces of the film adhesive thereby securing the diced semiconductor chips to the support surface to create first chip subassemblies ( 52 ). The diced semiconductor chip and support surface of each of a plurality of the first chip subassemblies are electrically connected, such as by wires ( 54 ), to create second chip subassemblies (( 56 ). At least a portion of at least some of the second chip subassemblies are encapsulated, such as with molding compound ( 58 ), to create semiconductor chip packages ( 60 ).

Claims (10)

1. A semiconductor chip packaging method comprising:

placing individual pieces of film adhesive on a support surface;

individually placing diced semiconductor chips on the individual pieces of the film adhesive thereby securing the diced semiconductor chips to the support surface to create first chip subassemblies;

electrically connecting the diced semiconductor chip and support surface of each of a plurality of the first chip subassemblies to create second chip subassemblies;

encapsulating at least a portion of at least some of the second chip subassemblies to create semiconductor chip packages;

selecting diced semiconductor chips having an adhesive layer on a back side thereof; and

wherein the individually placing step comprises placing the diced semiconductor chips on the individual pieces of the film adhesive with the adhesive layer contacting the film adhesive.

2. The method according to claim 1 wherein selecting step is carried out with the adhesive layer comprising a dielectric film adhesive layer.

3. A semiconductor chip package made according to the method of claim 1 .

4. A semiconductor chip package made according to the method of claim 2 .
