US Patent 7919361 Semiconductor package with position member

The present disclosure provides a very thin semiconductor package including a leadframe with a die-attach pad and a plurality of lead terminals, a die attached to the die-attach pad and electrically connected to the lead terminals via bonding wires, a position member disposed upon the die and/or die-attach pad, and a molding material encapsulating the leadframe, the die, and the position member together to form the semiconductor package. The method for manufacturing a very thin semiconductor package includes disposing a first position member on one side of the die-attach pad of a leadframe, attaching a die onto the opposite side of the die-attach pad, optionally disposing a second position member on top of the die, electrically connecting the die to the lead terminals of the leadframe, and encapsulating the leadframe, the die, and the position member(s) together to form the very thin semiconductor package.
