摘要:
MEMS devices having discharge circuits. In some embodiments, a MEMS device can include a substrate and an electromechanical assembly implemented on the substrate. The MEMS device can further include a discharge circuit implemented relative to the electromechanical assembly. The discharge circuit can be configured to provide a preferred arcing path during a discharge condition affecting the electromechanical assembly. The MEMS device can be, for example, a switching device, a capacitance device, a gyroscope sensor device, an accelerometer device, a surface acoustic wave (SAW) device, or a bulk acoustic wave (BAW) device. The discharge circuit can include a spark gap assembly having one or more spark gap elements configured to facilitate the preferred arcing path.

Disclosed herein are switching or other active FET configurations that implement a main-auxiliary branch design. Such designs include at least two FETs, an auxiliary FET providing an auxiliary path and a main FET providing a main path. Distortions that are generated in the main path, such as third-order harmonics and/or intermodulation distortions, can be reduced by distortions generated in the auxiliary path. This can be accomplished by applying a tailored gate bias to the auxiliary path so that the auxiliary path generates signals with distortions of a similar magnitude but opposite in phase relative to the distortions of the signals in the main path. Accordingly, the overall performance in the active FET is improved by reducing these distortions or nonlinearities.

Field-effect transistor (FET) devices are described herein that include one or more body contacts implemented near source, gate, drain (S/G/D) assemblies to improve the influence of a voltage applied at the body contact on the S/G/D assemblies. For example, body contacts can be implemented between S/G/D assemblies rather than on the ends of such assemblies. This can advantageously improve body contact influence on the S/G/D assemblies while maintaining a targeted size for the FET device.

摘要:
Radio-frequency (RF) devices are fabricated by providing a field-effect transistor (FET) formed over a an oxide layer formed on a substrate layer and removing at least a portion of the substrate layer to form an opening exposing at least a portion of a backside of the oxide layer, the opening being positioned to enhance RF performance for one or more components of the RF device.

Silicon-on-insulator (SOI) devices having contact layer. In some embodiments, a radio-frequency (RF) device can include a field-effect transistor (FET) implemented over a substrate layer, and an insulator layer implemented between the FET and the substrate layer. The RF device can further include a contact layer implemented between the insulator layer and the substrate layer to allow adjustment of RF performance of the FET. In some embodiments, such an RF device can be implemented as an RF switch in various products such as a die, a packaged module, and a wireless device.

Microelectromechanical systems (MEMS) having contaminant control features. In some embodiments, a MEMS die can include a substrate and an electromechanical assembly implemented on the substrate. The MEMS die can further include a contaminant control component implemented relative to the electromechanical assembly. The contaminant control component can be configured to move contaminants relative to the electromechanical assembly. For example, such contaminants can be moved away from the electromechanical assembly.
