摘要： A heat-sensitive apparatus includes a substrate with a top surface, one or more bars being rotatably joined to the surface and having bimorph portions, and a plate rotatably joined to the surface and substantially rigidly joined to the one or more bars. Each bimorph portion bends in response to being heated. The one or more bars and the plate are configured to cause the plate to move farther away from the top surface in response to the one or more bimorph portions being heated.

摘要： A freely rotatable micromechanical plate is achieved by employing at least three rotatable plates that are each suspended from a substrate via respective springs, and are coupled via other respective springs to at least three moveable plate attachment points, so that rotation of the rotatable plates about an axis transfers motion to the moveable plate attachment points. Respective posts couple the movement of each respective moveable plate attachment point to a moveable plate. In operation, the rotatable plates may be individually rotated, and the resulting motion of each rotatable plate is passed to its respective moveable plate attachment point. The combined motion of the moveable plate attachment points is passed to the moveable plate via the posts. Using proper control, the plate may be made to tip, tilt and piston. Advantageously, the piston motion may achieve a high vertical movement frequency response.

摘要： Targeted heating is employed to essentially only heat a material that is used as a spacer and to bond a first chip of a flip-chip to a second chip thereof and not the rest of the chips. In order to heat only the spacer-bonding material, one or more wires are located within, or adjacent to, the spacer-bonding material, and an electrical current is passed through the one or more wires causing them to heat. At the time of final bonding the heat generated by the one or more wires causes the spacer-bonding material to heat to its final curing temperature.

摘要： A MEMS device achieves a large angle of rotation of a plate about 2 independent axes by employing a handle portion of the plate which is isolated by respective springs coupling the handle portion to each of two actuators. A first actuator, which rotates the mirror about the same axis as done in U.S. Pat. No. 6,781,744 is essentially the same structure disclosed therein, but with the mirror plate thereof shrunken in size. This shrunken plate is coupled by a spring to the mirror plate of the instant invention. Movement of the shrunken plate causes corresponding movement of the handle portion, and hence the mirror. A second actuator, coupled by another spring to the mirror plate of the instant invention, rotates about a second axis that is perpendicular to the first axis and parallel to the substrate. The second actuator includes an actuator plate and an electrode thereunder.

摘要： A representative embodiment of the invention provides a thermal actuator for a MEMS-based relay switch. The thermal actuator has an “active” arm that is movably mounted on a substrate. The “active” arm has (i) a thermal expansion layer and (ii) a resistive heater that is electrically isolated from the thermal expansion layer. The thermal expansion layer is adapted to expand in response to a temperature change induced by a control current flowing through the resistive heater, thereby bending the “active” arm and moving that arm with respect to the substrate. Due to the fact that mechanical and electrical characteristics of the “active” arm are primarily controlled by the thermal expansion layer and the resistive heater, respectively, those characteristics can be optimized independently to obtain better operating characteristics for MEMS-based relay switches of the invention compared to those attained in the prior art.
