Abstract: Some exemplary embodiments of a III-nitride power device including a HEMT with multiple interconnect metal layers and a solderable front metal structure using solder bars for external circuit connections have been disclosed. The solderable front metal structure may comprise a tri-metal such as TiNiAg, and may be configured to expose source and drain contacts of the HEMT as alternating elongated digits or bars. Additionally, a single package may integrate multiple such HEMTs wherein the front metal structures expose alternating interdigitated source and drain contacts, which may be advantageous for DC-DC power conversion circuit designs using III-nitride devices. By using solder bars for external circuit connections, lateral conduction is enabled, thereby advantageously reducing device Rdson.

Abstract: Some exemplary embodiments of high voltage cascoded III-nitride semiconductor package utilizing clips on a package support surface have been disclosed. One exemplary embodiment comprises a III-nitride transistor attached to a package support surface and having an anode of a diode stacked over a source of the III-nitride transistor, a first conductive clip coupled to a gate of the III-nitride transistor and the anode of the diode, and a second conductive clip coupled to a drain of the III-nitride transistor. The conductive clips are connected to the package support surface and expose respective flat portions that are surface mountable. In this manner, reduced package footprint, improved surge current capability, and higher performance may be achieved compared to conventional wire bonded packages. Furthermore, since a low cost printed circuit board (PCB) may be utilized for the package support surface, expensive leadless fabrication processes may be avoided for cost effective manufacturing.

Abstract: In one implementation, a power unit for plugging into a mother board includes a power module situated on a substrate. The substrate is situated on conductive slats, each having an extended end away from the power module. Each of the conductive slats provides a mounting contact of the power unit. Each mounting contact is electrically coupled to the power module by electrical routing in the substrate. The mounting contacts are configured to provide electrical connection between the power module and the mother board.
