    摘要: A process for fabricating mechanically interconnected, released, electrically isolated metal microstructures, and circuit components and actuators produced by the process. A dielectric stack on a substrate is patterned and etched to produce trenches in which a metal such as tungsten is deposited. The dielectric is removed from selected regions of the metal to expose metal beams, and to form mechanically interconnecting, electrically insulating hinges supporting the beams. The beams and hinges are then released for relative motion. Electrical potentials may be established between adjacent beams to produce controlled motion.

    摘要: The present invention provides a method and apparatus for forming reliable interconnects in which the overlap of the line over the plug or via is minimized or eliminated. In one aspect, a barrier plug comprised of a conductive material, such as tungsten, is deposited over the via to provide an etch stop during line etching and to prevent diffusion of the metal, such as copper, into the surrounding dielectric material if the line is misaligned over the via. Additionally, the barrier plug prevents an overall reduction in resistance of the interconnect and enables reactive ion etching to be employed to form the metal line. In another aspect, reactive ion etching techniques are employed to selectively etch the metal line and the barrier layer to provide a controlled etching process which exhibits selectivity for the metal line, then the barrier and then the via or plug.

    摘要: A bidirectional optical scanner assisting in mammography is revealed. The optical scanner that calculates functional images obtained by diffuse optical tomography, used in combination with a mammography machine can reduce the number of mammograms taken and the dose exposure. The bidirectional optical scanner includes a compression module, a first optical detection module, and a second optical detection module. The same test position of the tested breast can be detected twice in different directions by the first and the second optical detection modules. No matter where the tumor is located, the tumor can be detected. Besides structural images provided by the mammography machine, functional tomographic images of the breast are obtained by the bidirectional optical scanner. Thus diagnostic accuracy in the detection of breast cancer is improved.

    摘要: The present invention is to a chemical vapor deposition process for depositing a substantially planar, highly reflective layer on a substrate, and is particularly useful for filling high aspect ratio holes in the substrate with metal-containing material. The substrate is placed in a process zone, and successive seeding and oriented crystal growth stages are performed on the substrate. In the seeding stage, the substrate is heated to temperatures T.sub.s, within a first lower range of temperatures .DELTA. T.sub.s, and a seeding gas is introduced into the process zone. The seeding gas deposits a substantially continuous, non-granular, and planar seeding layer on the substrate. Thereafter, in an oriented crystal growth stage, the substrate is maintained at deposition temperatures T.sub.d, within a second higher range of temperatures .DELTA. T.sub.D, and deposition gas is introduced into the process zone. The deposition gas forms an oriented crystal growth layer on the seeding layer, the oriented crystal growth layer having a highly reflective surface that results from highly oriented, relatively large crystals that grow on the seeding layer.

    摘要: An image reconstruction method is described as follows. A structural image of an object is obtained. An actual optical detected result of the object is obtained. An inhomogeneous initial state is determined based on the structural image. At least one solution converged with the actual optical detected result is determined by iteratively calculating a physical model from the inhomogeneous initial state. The image of the object is reconstructed based on the solution.
