Abstract:
A high-voltage transistor (HVT) structure adapts a low-voltage transistor (LUT) to high-voltage environments. The HVT structure includes a drain node, a source node, a control gate, and a field electrode. The drain node and the source node define a conductive channel, in which mobilized charges are regulated by the control gate. While being isolated from the control gate, the field electrode is configured to spread the mobilized charges in response to a field voltage. The field electrode is structured and routed to prevent charge sharing with any one of the drain node, source node, or control gate. Advantageously, the isolated field electrode minimizes the capacitance of the control gate as well as the drain and source nodes, such that the HVT can switch with less power loss and a more robust performance in a high-voltage environment.

Claim (Index 11):
A device, comprising:\n a first die having a MOS transistor including a first drain node, a first control gate, and a first source node; a second die separated from the first die, and having a gallium nitride (GaN) transistor including a second drain node, a second source node, a second control gate, and a field electrode insulated from the second control gate and the second source node within the GaN transistor; a first conductor external to the first die and the second die, and coupling the field electrode of the GaN transistor to the first source node of the MOS transistor; and a second conductor external to the first die and the second die, and coupling the second control gate of the GaN transistor to the first source node of the MOS transistor.
