    摘要: A micromechanical pumping system is formed on a substrate surface. The pumping system uses a pumping element which pumps a fluid through valves which move in a plane substantially parallel to the substrate surface. An electromagnetic actuating mechanism may also be fabricated on the surface of the substrate. Magnetic flux produced by a coil around a permeable core may be coupled to a permeable member affixed to a pumping element. The permeable member and pumping element may be configured to move in a plane parallel to the substrate. The electromagnetic actuating mechanism gives the pumping system a large throw and substantial force, such that the fluid pumped by the pumping system may be pumped through a transdermal cannula to deliver a therapeutic substance to the tissue underlying the skin of a patient.

    摘要: A separated MEMS thermal actuator is disclosed which is largely insensitive to creep in the cantilevered beams of the thermal actuator. In the separated MEMS thermal actuator, a inlaid cantilevered drive beam formed in the same plane, but separated from a passive beam by a small gap. Because the inlaid cantilevered drive beam and the passive beam are not directly coupled, any changes in the quiescent position of the inlaid cantilevered drive beam may not be transmitted to the passive beam, if the magnitude of the changes are less than the size of the gap.

    摘要: A material for bonding a first wafer to a second wafer, which includes an insulating adhesive with conductive particles embedded in the adhesive substance. When the adhesive is applied and melted or fused, and pressure is applied between the first wafer and the second wafer, the first wafer approaches the second wafer until a minimum separation is reached, defined by a dimension of the conductive particles. Each of the first wafer and the second wafer may have circuitry formed thereon, and the conductive particles may form a conductive path between the circuitry on one wafer and the circuitry on the other wafer. Advantageously, the high fusing temperature required by the insulating adhesive may also serve to activate a getter material, formed in the device cavity between the first wafer and the second wafer.

    摘要: An optical MEM device is fabricated with a patterned device layer formed on a silicon wafer. Preferably, the patterned device layer is patterned with plurality of ribbons and/or access trenches. The central portion of the ribbon is released from the silicon wafer using a selective etch process, wherein a cavity is formed under the central portion of the ribbon, while opposing ribbon ends remain attached to the wafer. The selective etching process preferably utilizes an enchant comprising xenon difluoride. In accordance with further embodiments, the silicon wafer is doped, patterned or otherwise modified to enhance the selectivity of the etching process.

    摘要: A operationally contacting hard disk drive system has reduced friction due to lower capillary adhesion between the disk surface and a transducer in a substantially continuous sliding relationship with the surface. The disk surface has an adhesion-reducing texture that includes a microscopic RMS roughness in a range between about 1.5 and 5.5 nanometers, or a number of asperities having a mean plane to peak height in a range between about 6 and 50 nanometers. The roughness may increase in a radially graded fashion to compensate for the increased linear velocity and concomitant frictional power loss near the outer diameter of the disk. It is important that the uppermost reaches of the textured surface are smooth but not flat in order to obtain lasting low friction operation, which is accomplished by constructing the surface with a highest approximately one percent having an average radius of curvature in a range between 2 microns and 100 microns. An area of the slider in apparent contact with the disk surface is preferably less than 1000 square microns, and a ratio between this nominal area and the mean to peak height is less than 0.3 meters. The slider may also include a substantial thickness of partially wetting material in contact with the disk, or may alternatively be textured with deep grooves or materials having differing wear rates, in order to provide reduced frictional adhesion despite wear of the slider.

    摘要: Controlled laser texturing of a magnetic recording disk is accomplished by use of a textured test band on the disk and an analyzing laser system to provide feedback to the texturing laser. The analyzing laser system determines, from diffracted laser light, the average height of the laser-induced bumps formed in the test band by the texturing laser. The analyzing laser beam is directed to the substrate surface and overlaps a group of individual bumps formed in a repetitive pattern. A scanning linear photodector array receives light diffracted from the surface. The digitized output of the array is the angular distribution of diffracted light intensities and is used to compute the average height of the bumps in the test band. The disk is then translated radially so that the texturing laser is aligned with the region of the disk where the textured landing zone is to be placed. Then, in response to the computed value of average bump height in the test band, a correction signal or signals is output to modify one or more parameters of the texturing laser so that the texturing laser can form bumps of the correct average height in the textured landing zone.
