  • MEMS device
    Patent number: 7102472
    Abstract: A MEMS device having a support frame positioned on a substrate surrounding a first electrode. A rigid flange portion at the top of the support frame is closely space from, and is connected to, a second electrode by relatively short spring members. RF conductors connected to respective first and second electrodes complete an RF switch. A dielectric layer on the first electrode forms a capacitive type device and includes an electrostatic shield layer on its surface. This electrostatic shield layer is connected to ground by a multi megohm bleeder resistance.

  • Low charging dielectric for capacitive MEMS devices and method of making same
    Publication number: 20060138604
    Abstract: An improved dielectric suitable for use in electronic and micro-electromechanical (MEMS) components. The dielectric includes silicon nitride having a percentage of Si:H bonds greater than a percentage of N:H bonds, in order to reduce the level of charge trapping of the silicon nitride.
