    摘要: In order to adjust an electric device, it is proposed to integrate a programmable memory unit into the device and to address said programmable memory unit without enlarging the footprint, via contact areas that are obtained by dividing previous contact areas. In this case, an adjustment value in particular for compensating for a fault tolerance is fed into the memory unit, an operating parameter being readjusted with the aid of said adjustment value. In each case two divided contact areas are short-circuited via a common soldering location during the mounting of the device.

    摘要: Apparatus, methods and systems for nano/micro machining. A lathe head has a microscopic pivot aperture for seating a conical tip. The conical tip is carried on a turnable part at one end thereof and is polished down to a microscopic apex. The microscopic pivot aperture is dimensioned for seating the concentric tip in the pivot aperture such that an apex of the conical tip protrudes through and beyond the aperture to a position in close proximity with the aperture. A driver system can comprise a rotator for axially rotating the turnable part, including the conical tip seated in the pivot aperture, and a forward pressure applicator for concurrently applying forward pressure to the conical tip in the direction of the pivot aperture. A light/particle beam system can be utilized to machine the rotating conical tip and the rotating turnable part, including the tip, can be easily removed after machining.

    摘要: The present disclosure provides a semiconductor structure. The semiconductor structure includes a cavity disposed in a substrate and enclosed by a first surface and a second surface opposite to the first surface. The semiconductor structure also includes a first electrode pair having a first electrode on the first surface and a second electrode on the second surface. The first electrode pair is configured to measure a first spacing between the first surface and the second surface. The semiconductor structure further includes a second electrode pair having a third electrode on the first surface and a fourth electrode on the second surface. The second electrode pair is configured to measure a second spacing between the first surface and the second surface.

    摘要: A reversible bonded microfluidic structure comprises an overhanging cap or gasket structure atop a continuous microfluidic channel wall. An overhanging gasket structure may reduce stress concentrations at the edge of the channel wall and can permit improved reversible adhesion of the channel wall and adjacent dry adhesive fibers. In one example, reversible adhesion of the overhanging channel wall gasket and adjacent dry adhesive fibers may approach 1 MPa in axial loading. An overhanging gasket structure of the microfluidic channel wall may comprise a single “fiber” that is continuous around the perimeter of the desired microfluidic channel shape, and may define a self-sealing gasket which will contain fluid. The overhanging gasket structure may be surrounded by further overhanging or undercut dry adhesive fibers to enhance the adhesion and help make the rest of the surface more tolerant to defects and surface roughness.

    摘要: According to an embodiment, a micro-fabricated test structure includes a structure mechanically coupled between two rigid anchors and disposed above a substrate. The structure is released from the substrate and includes a test layer mechanically coupled between the two rigid anchors. The test layer includes a first region having a first cross-sectional area and a constricted region having a second cross-sectional area smaller than the first cross-sectional area. The structure also includes a first tensile stressed layer disposed on a surface of the test layer adjacent the first region.
