Abstract:
A method of attaching at least one semiconductor die having an active surface thereon to at least one lead of a leadframe having a plurality of leads, comprising:providing a semiconductor wafer having a plurality of semiconductor die formed thereon;separating the plurality of semiconductor die formed on said semiconductor wafer, each semiconductor die of said plurality of semiconductor die having an active surface;identifying criteria for an acceptable semiconductor die of said plurality of semiconductor die;identifying an acceptable semiconductor die having said identifying criteria;applying an adhesive in a wet film state in the form of one of a liquid and a paste in a predetermined pattern to portions of the active surface of said acceptable semiconductor die;partially curing the adhesive from the wet film state to an intermediate tacky and flowable state while on portions of the active surface of said acceptable semiconductor die; andremovably attaching a portion of at least one leads of the plurality of leads of the leadframe to a portion of the active surface of said acceptable semiconductor die using the intermediate partially cured tacky and flowable state of said adhesive.
