Abstract: A high-voltage transistor (HVT) structure adapts a low-voltage transistor (LVT) 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.

Abstract: To form a MOSFET over a silicon carbide substrate, when a heat treatment accompanied by nitration is carried out to reduce the interface state density in the vicinity of the boundary between a gate insulating film and a silicon carbide substrate, CV hysteresis occurs due to the relationship between the capacitance and gate voltage of the MOSFET, thereby reducing the reliability of a semiconductor device. To solve the above problem, a heat treatment accompanied by nitration is carried out on the insulating film formed over the silicon carbide substrate (step S7). Then, the insulating film is heated in an inert gas atmosphere (step S9). Thereafter, a field effect transistor having a gate insulating film which is composed of the insulating film is formed over the silicon carbide substrate.
