Abstract:
1. A packaged semiconductor device, comprising: a planar leadframe embedded in a non-conducting polymer having a plurality of electrically conductive leads but without a die support, said non-conducting polymer having a plurality of termini disposed in a pattern corresponding to a pattern of contacts on a surface of a die; wherein an upper surface of the non-conducting polymer is in the same plane as an upper surface of the plurality of leads forming a uniform surface; a die positioned on top of the non-conducting polymer, the die having a plurality of stud bumps disposed in a pattern corresponding to the pattern of termini on the non-conducting polymer so that the stud bumps on the die are in contact with the corresponding termini on the non-conducting polymer; a plurality of electrical paths between the plurality of termini and the plurality of leads on the uniform surface, wherein the electrical paths comprise electrically conductive ink; and an over-molded, non-conducting polymer encapsulating the die.
