Abstract:
A method of attaching a semiconductor device having an active surface thereon to a leadframe having a plurality of leads, comprising:providing a semiconductor wafer having a plurality of semiconductor devices formed thereon;separating the plurality of semiconductor devices formed on said semiconductor wafer, each semiconductor device of the plurality of semiconductor devices having an active surface;identifying criteria for an acceptable semiconductor device of said plurality of semiconductor devices;identifying an acceptable semiconductor device having said identifying acceptable 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 device;partially curing the adhesive from the wet film state to an intermediate tacky and flowable state; andremovably attaching portions of the plurality of leads of the leadframe to the portions of the active surface of said acceptable semiconductor device using the intermediate partially cured tacky and flowable state of said adhesive.
