摘要: In the preferred embodiments, a method to reduce gate leakage and dispersion of group III-nitride field effect devices covered with a thin in-situ SiN layer is provided. This can be obtained by introducing a second passivation layer on top of the in-situ SiN-layer, in combination with cleaning of the in-situ SiN before gate deposition and before deposition of the second passivation layer.

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: Disclosed are methods of growing III-V epitaxial layers on a substrate, semiconductor structures thus obtained, and devices comprising such semiconductor structures. An example semiconductor substrate includes a substrate and a buffer layer on top of the substrate, where a conductive path is present between the substrate and buffer layer. A conductive path may be present in the conductive interface, and the conductive path may be interrupted by one or more local electrical isolations. The local electrical isolation(s) may be positioned with the device such that at least one of the local electrical isolation(s) is located between a high voltage terminal and a low voltage terminal of the device.

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).
