Abstract:
A multi-package module package includes a plurality of individually packaged chips. Yield is increased over conventional multi-chip packages because the individual chips can be inexpensively and fully tested before being placed into the multi-package module package. Also, the manufacturing process is simpler because the individual chips can be more easily handled while being tested and attached to the multi-package module package. Further, a standard component surface mount process is used for package assembly. Thus, no new capital investment or process development is needed.

This substrate carries two planes or layers of patterned metal (19, 20) thus providing two principal levels of interconnection. A programmable amorphous silicon insulation layer (21) is placed between the metal layers. There are sheet lower metal layers with an insulator which permit power distribution across the wafer. Connections between the metal layers or between the metal layer and the substrate can be made through via holes in the insulator layers or layers, respectively. Pedestals are provided for bonding. Systems can be formed by interconnection discrete die formed on the wafer or by connection thereto, with hybrid circuits being disclosed.

Abstract:
Disclosed are structures and methods related to a barrier layer for metallization of a selected semiconductor such as indium gallium phosphide (InGaP). In some embodiments, the barrier layer can include tantalum nitride (TaN). Such a barrier layer can provide desirable features such as barrier functionality, improved adhesion of a metal layer, reduced diffusion, reduced reactivity between the metal and InGaP, and stability during the fabrication process. In some embodiments, structures formed in such a manner can be configured as an emitter of a gallium arsenide (GaAs) heterojunction bipolar transistor (HBT) or an on-die high-value capacitance element. In some embodiments, some of the foregoing structures can be configured as a capacitance element having a capacitance value representative of the thickness of the emitter layer. Accordingly, monitoring of such a capacitance value during various HBT processes allows monitoring of the integrity of the emitter layer.

Abstract:
A semiconductor package has a capacitor die and a packaging substrate. The capacitor die is coupled to circuitry on a front or back side of a die coupled to the packaging substrate for providing decoupling capacitance. In one example, the capacitor die is coupled to a land side of the packaging substrate in an area depopulated of a packaging array and adjacent to the packaging array. In another example, the capacitor die may be stacked on the die and coupled through wire bonds to circuitry on the die. The capacitor die reduces impedance of the integrated circuit allowing operation at higher frequencies.
