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).
