    Abstract: The present invention relates to MEMS device that comprises a first electrode, and a second electrode suspended with a distance to the first electrode with the aid of a suspension structure. The MEMS device further comprises at least one deformation electrode. The second electrode or the suspension structure or both are plastically deformable upon application of an electrostatic deformation force via the deformation electrode. This way, variations in the off-state position of the second electrode that occur during fabrication of different devices or during operation of a single device can be eliminated.

    Abstract: A microelectrical device comprising two generally parallel electrodes (20,21) at least one of which is movable, and at least one of the electrodes comprising a layer of a semiconductor presenting space charge characteristics. The electrodes have a closed position an open position. A spring effect biases the movable electrode (21) towards the open position. When the movable electrode (21) is closed by a first voltage pulse (P1) a sufficiently high space charge density (10) is generated to hold the movable electrode (21) closed. When zero voltage is applied the movable electrode (21) is held closed by the built in space charge until the application of a second voltage pulse (P2) which decreases the space charge in the semiconductor (10) to allow the movable electrode(s) to be moved to the open position by the spring effect.

    Abstract: An RF MEMS switch having asymmetrical spring rigidity. The RF MEMS switch has supporting members spaced apart in a certain interval on a substrate, a membrane being a motion member suspended by plural spring members extended on both sides of the membrane, and a bottom electrode being a contact surface on an upper surface of the substrate facing a bottom surface of the membrane, wherein the plural spring members placed on opposite sides of the membrane have asymmetrical rigidity, and a portion of the membrane on a side of stronger spring rigidity is first separated from the contact surface when the RF MEMS switch is turned off. The present invention has an advantage of easy separation of the switch from the contact surface, when the switch is turned off, due to the different rigidity of the springs located on the sides of the membrane.

    Abstract: The invention relates to an electrostatic microswitch which is intended to connect electrically two strip conductors which are disposed on an insulating support (21), the two strip conductors are connected electrically by conducting means (38) which are provided in the central part of deformable means (28) which can be deformed in relation to the support under the effect of an electrostatic force generated by control electrodes (25, 48; 26, 58). The control electrodes are distributed facing one another on the deformable means and the support, such as to form capacitive means around the aforementioned conducting means. The control electrodes are associated with insulating stop elements (35, 36) which are provided in order to prevent a short circuit between electrodes of the capacitive means during the deformation of the deformable means. The distance between the deformable means and the ends of the strip conductors is less than or equal to the distance between the insulating stop elements associated with the control electrodes and the control electrodes located opposite.

    Abstract: A phased-array antenna system and other types of radio frequency (RF) devices and systems using microelectromechanical switches (“MEMS”) and low-temperature co-fired ceramic (“LTCC”) technology and a method of fabricating such phased-array antenna system and other types of radio frequency (RF) devices are disclosed. Each antenna or other type of device includes at least two multilayer ceramic modules and a MEMS device fabricated on one of the modules. Once fabrication of the MEMS device is completed, the two ceramic modules are bonded together, hermetically sealing the MEMS device, as well as allowing electrical connections between all device layers. The bottom ceramic module has also cavities at the backside for mounting integrated circuits. The internal layers are formed using conducting, resistive and high-k dielectric pastes available in standard LTCC fabrication and low-loss dielectric LTCC tape materials.

    Abstract: A microelectromechanical system includes separate conducting elements. An electromechanically deformable element can be switched between a first stable position and a second stable position. Contact elements allow for electrical continuity to be established between the separate conducting elements. Switch control elements ensure that the first deformable element switches so as to establish electrical continuity between the separate conducting elements in the second stable position, by contact between the contact elements, and to break electrical continuity by separating the contact elements in the first stable position. The separate conducting elements and the contact elements are carried by the deformable element.
