    摘要: An electronic device can include a drain electrode of a high electron mobility transistor overlying a channel layer; a source electrode overlying the channel layer, wherein a lowermost portion of the source electrode overlies at least a portion of the channel layer; and a gate electrode of the high electron mobility transistor overlying the channel layer; and a current limiting control structure that controls current passing between the drain and source electrodes. The current limiting control structure can be disposed between the source and gate electrodes, the current limiting control structure can be coupled to the source electrode and the first high electron mobility transistor, and the current limiting control structure has a threshold voltage. The current limiting control structure can be a Schottky-gated HEMT or a MISHEMT.

    摘要: An electronic device can include a channel layer; an access region having an aluminum content substantially uniform or increasing with distance from the channel layer; and a gate dielectric layer overlying and contacting the channel layer. A process of forming an electronic device can include providing a substrate and a channel layer of a III-V semiconductor material over the substrate; forming a masking feature over the channel layer; and forming an access region over the channel layer. In an embodiment, the channel layer can include GaN, and the access region has an aluminum content that is substantially uniform or increases with distance from the channel layer. In another embodiment, the process can include removing at least a portion the masking feature and forming a gate dielectric layer over the channel layer. A dielectric film of the masking feature or the gate dielectric layer contacts the channel layer.
