Abstract:
A method of making a semiconductor device assembly having a first semiconductor die having at least one bond pad on an active surface thereof and having a back side and having a second semiconductor die having at least one bond pad on an active surface thereof and having a back side, said first semiconductor die and said second semiconductor die mounted on a lead frame having a plurality of leads, said method comprising:providing a carrier substrate having a first side and a second side; attaching the back side of the first semiconductor die and the back side of the second semiconductor die to the first side of the carrier substrate; attaching at least one lead of the plurality of leads to a portion of the active surface of the first semiconductor die; attaching at least one other lead of the plurality of leads to a portion of the active surface of the second semiconductor die; forming at least one wire bond extending between the at least one bond pad on the active surface of the first semiconductor die and the at least one lead of the plurality of leads of the lead frame attached to a portion of the active surface of the first semiconductor die; and forming at least one wire bond extending between the at least one bond pad on the active surface of the second semiconductor die and the at least one other lead of the plurality of leads of the lead frame attached to a portion of the active surface of the second semiconductor die.
