Patent ID: 6936525

Claim:
A method of manufacturing a chip-like electronic component, comprising the steps of: pasting an adhesive material on a substrate, said adhesive material having a property to retain an adhesive strength prior to a weakening process and to lose said adhesive strength after said weakening process; fixing a plurality of similar and/or different types of non-defective semiconductor chips on said adhesive material with an electrode surface thereof facing down, the electrode surface of the chips being in direct contact with the adhesive material; coating a whole area including said plurality of non-defective semiconductor chips and interspaces therebetween with a protective material, wherein the step of coating is performed prior to forming electrical connections to electrodes of said semiconductor chips; applying a weakening process to said adhesive material to weaken said adhesive strength of said adhesive material so as to peel off a pseudo wafer which bonds said plurality of non-defective semiconductor chips as covered with said protective material; and thereafter performing processing of said pseudo-wafer to form electrical connections with electrodes of the chips in the pseudo-wafer; dicing said plurality of similar and/or different types of semiconductor chips by cutting said protective material in said interspaces therebetween.
