Abstract:
Circuit-Under-Pad (CUP) device topologies for high current lateral GaN power transistors comprise first and second levels of on-chip metallization M1 and M2; M1 defines source, drain and gate finger electrodes of a plurality of sections of a multi-section transistor and a gate bus; M2 defines an overlying contact structure comprising a drain pad and source pads extending over active regions of each section. The drain and source pads of M2 are interconnected by conductive micro-vias to respective underlying drain and source finger electrodes of M1. The pad structure and the micro-via interconnections are configured to reduce current density in self-supported widths of source and drain finger electrodes, i.e. to optimize a maximum current density for each section. For reduced gate loop inductance, part of each source pad is routed over the gate bus. Proposed CUP device structures provide for higher current carrying capability and reduced drain-source resistance.

Claim (Index 23):
The semiconductor device structure of  claim 11 , wherein the source contact areas comprise parts of a source bus;\n each drain pad extending laterally in a width direction over a central part of the active region of the section; the source bus comprising first and second portions extending over the underlying first and second portions of the gate bus for the section; an intermetal dielectric layer provided between the first and second level metallization layers M1 and M2; the drain pad being interconnected by conductive micro-vias through the intermetal dielectric layer to underlying drain finger electrodes, and the source finger electrodes being connected laterally to second portions of the source bus.
