Patent ID: 6979598

Claim:
A method of attaching at least one semiconductor die having an active surface thereon to at least one lead of a plurality of leads of a leadframe, the at least one semiconductor die to be separated from a semiconductor wafer having a plurality of semiconductor dice thereon comprising: determining criteria for an acceptable semiconductor die of the plurality of semiconductor dice; testing each semiconductor die of the semiconductor wafer to determine if the criteria for the acceptable semiconductor die are included in any semiconductor die of the plurality of semiconductor dice; applying an adhesive in a wet film state in a form of one of a liquid and a paste in a predetermined pattern to portions of the active surface of the acceptable semiconductor die; partially curing the adhesive from the wet film state to an intermediate tacky and flowable state; removably attaching a portion of the at least one lead of the plurality of leads of the leadframe to a portion of the active surface of the acceptable semiconductor die using the partially cured intermediate tacky and flowable state adhesive; identifying additional criteria of the acceptable semiconductor die attached to the leadframe; testing the acceptable semiconductor die attached to the at least one lead of the plurality of leads of the leadframe to determine if the additional criteria are present in the acceptable semiconductor die; removing the at least one lead of the plurality of leads of the leadframe attached to the acceptable semiconductor die therefrom if the acceptable semiconductor die is determined to be an unacceptable semiconductor die based on the testing; and reworking the unacceptable semiconductor die.
