    摘要: A method for manufacturing a III-V CMOS device is disclosed. The device includes a first and second main contact and a control contact. In one aspect, the method includes providing the control contact by using damascene processing. The method thus allows obtaining a control contact with a length of between about 20 nm and 5 μm and with good Schottky behavior. Using low-resistive materials such as Cu allows reducing the gate resistance thus improving the high-frequency performance of the III-V CMOS device.

    摘要: A method is disclosed for producing Group III-N field-effect devices, such as HEMT, MOSHFET, MISHFET or MESFET devices, comprising two active layers, e.g. a GaN/AlGaN layer. The method produces an enhancement mode device of this type, i.e. a normally-off device, by providing a passivation layer on the AlGaN layer, etching a hole in the passivation layer and not in the layers underlying the passivation layer, and depositing the gate contact in the hole, while the source and drain are deposited directly on the passivation layer. The characteristics of the active layers and/or of the gate are chosen such that no two-dimensional electron gas layer is present underneath the gate, when a zero voltage is applied to the gate. A device with this behavior is also disclosed.

    摘要: A semiconductor device is disclosed. In one aspect, the device has a first and second active layer on a substrate, the second active layer having a higher bandgap than the first active layer, being substantially Ga-free and including at least Al−. The device has a gate insulating layer on a part of the second active layer formed by thermal oxidation of a part of the second active layer. The device has a gate electrode on at least a part of the gate insulating layer and a source electrode and drain electrode on the second active layer. The device has, when in operation and when the gate and source electrode are at the same voltage, a two-dimensional electron gas layer between the first and second active layer only outside the location of the gate electrode and not at the location of the gate electrode.

    摘要: Disclosed are methods of growing III-V epitaxial layers on a substrate, a semiconductor structure comprising a substrate, a device comprising such a semiconductor structure, and an electronic circuit. Group III-nitride devices, such as, for example, high-electron-mobility transistors, may include a two-dimensional electron gas (2DEG) between two active layers. For example, the 2DEG may be between a GaN layer and a AlGaN layer. These transistors may work in depletion-mode operation, which means the channel has to be depleted to turn the transistor off. For certain applications, such as, for example, power switching or integrated logic, negative polarity gate supply is undesired. Transistors may then work in enhancement mode (E-mode).
