Abstract: In one aspect of the invention, an integrated circuit package is described. The integrated circuit package includes a substrate formed from a dielectric material that includes multiple electrical contacts and conductive paths. An upper lead frame is attached with and underlies the substrate. The upper lead frame is electrically connected with at least one of the contacts on the substrate. The active surface of an integrated circuit die is electrically and physically coupled to the upper lead frame through multiple electrical connectors. A lower lead frame may be attached with the back surface of the integrated circuit die. A passive device is positioned on and electrically connected with one of the contacts on the substrate and/or the upper lead frame.

Abstract: An integrated circuit package is described that includes a substrate, a leadframe and one or more integrated circuits that are positioned between the substrate and the leadframe. Multiple electrical components may be attached to one or both sides of the substrate. The active face of the integrated circuit is electrically and physically connected to the substrate. The back side of the integrated circuit is mounted on a die attach pad of the leadframe. The leadframe includes multiple leads that are physically attached to and electrically coupled with the substrate. A molding material encapsulates portions of the substrate, the leadframe and the integrated circuit. Methods for forming such packages are also described.

Abstract: A semiconductor chip package having multiple leadframes is disclosed. Packages can include a first leadframe having a first plurality of electrical leads and a die attach pad having a plurality of tie bars, a second leadframe generally parallel to the first leadframe and having a second plurality of electrical leads, and a mold or encapsulant. Tie bars can be located on three main sides of the die attach pad, but not the fourth main side. Gaps in the first and second plurality of electrical leads can be enlarged or aligned with each other to enable the elimination of mold flash outside the encapsulated region, which can be accomplished with mold cavity bar protrusions. Additional components can include a primary die, a secondary die, an inductor and/or a capacitor. The first and second leadframes can be substantially stacked atop one another, and one or both leadframes can be leadless leadframes.
