Microelectromechanical systems (MEMS) switches are disclosed. The MEMS switch may have an actuation voltage greater than the expected voltage of a signal being passed by the MEMS switch in normal operation. The MEMS switches may include a distributed hinge structure in some embodiments. Radial contact pads are included in some embodiments, with or separate from the distributed hinge.

Microelectromechanical systems (MEMS) switch and related methods

An integrated circuit package can contain a semiconductor die and provide electrical connections between the semiconductor die and additional electronic components. The integrated circuit package can reduce stress placed on the semiconductor die due to movement of the integrated circuit package due to, for example, temperature changes and/or moisture levels. The integrated circuit package can at least partially mechanically isolate the semiconductor die from the integrated circuit package.

Integrated circuit packages to minimize stress on a semiconductor die

Optically isolated micromachined (MEMS) switches and related methods are described. The optically isolated MEMS switches described herein may be used to provide isolation between electronic devices. For example, the optically isolated MEMS switches of the types described herein can enable the use of separate grounds between the receiving electronic device and the control circuitry. Isolation of high-voltage signals and high-voltage power supplies can be achieved by using an optical isolator and a MEMS switch, where the optical isolator controls the state of the MEMS switch. In some embodiments, utilizing optical isolators to provide high voltages, the need for electric high-voltage sources such as high-voltage power supplies and charge pumps may be removed, thus removing the cause of potential damage to the receiving electronic device. In one example, the optical isolator and the MEMS switch may be co-packaged on the same substrate.

Microelectromechanical systems (MEMS) switches are described. The MEMS switches can be actively opened and closed. The switch can include a beam coupled to an anchor on a substrate by one or more hinges. The beam, the hinges and the anchor may be made of the same material in some configurations. The switch can include electrodes, disposed on a surface of the substrate, for electrically controlling the orientation of the beam. The hinges may be thinner than the beam, resulting in the hinges being more flexible than the beam. In some configurations, the hinges are located within an opening in the beam. The hinges may extend in the same direction of the axis of rotation of the beam and/or in a direction perpendicular to the axis of rotation of the beam.
