Abstract:
A method of attaching a semiconductor die to a portion of a lead frame, said method comprising:providing a lead frame having a plurality of lead fingers thereon, at least one lead finger of said plurality of lead fingers having an attaching surface;providing a semiconductor die having an active surface;selecting a non-conductive polymer adhesive from a group that is tacky and compliant at room temperature;applying said non-conductive polymer adhesive in at least one line on at least a portion said active surface of said semiconductor die;retaining said non-conductive polymer adhesive at room temperature;urging said active surface of said semiconductor die and said attaching surface of said at least one lead finger of said plurality of lead fingers of said lead frame together at room temperature to attach said semiconductor die and said at least one lead finger of said plurality of lead fingers of said lead frame together connecting said attaching surface of said at least one lead finger of said plurality of lead fingers of said lead frame and said active surface of said semiconductor device.
