摘要： A micro-electro-discharge machining apparatus includes a substrate, a plurality of electrically conductive electrodes on the substrate arranged in an array, and a plurality of electrical interconnect lines formed on the substrate extending to one or more of the electrodes. An electrical power source is connected from one of its terminals through a resistor to each of the interconnect lines and from its other terminal to a workpiece to be machined. The electrodes connected to different interconnect lines may charge and discharge independently of each other, speeding up the machining process. An interconnect line may extend individually to each electrode so that all of the electrodes can charge and discharge independently of the others. The capacitor that is charged to produce the discharge voltage may be a separate discrete capacitor or a conductive substrate.

摘要： Micro-electro-discharge machining is carried out utilizing a semiconductor array electrode having a substrate with a face surface and electrode protrusions extending from the face surface. The array electrode may be formed by lithographically patterning a semiconductor wafer such as a silicon wafer utilizing lithographic techniques of the type used in semiconductor device processing. The electrode protrusions in the surface of the substrate may be coated with a conducting metal. The electrode is positioned adjacent to a workpiece and a power supply is connected to the electrode and the workpiece to charge a capacitor until discharge takes place between the electrode protrusions and the surface of the workpiece, to electro-discharge-machine the workpiece to replicate the pattern of electrode protrusions into the workpiece. The semiconductor electrode is formed to be consumed during the machining process, during which many individual workpiece elements can be micromachined in parallel to provide rapid and economical production of micromachined parts.

摘要： A micromachined probe apparatus and methods for making and using same to characterize liquid in a fluidic channel and map embedded charge in a sample on a substrate are provided. The probe apparatus includes an integrated scanning tip and a dither actuation mechanism. The actuation is achieved using a bent-beam electrothermal actuator, and the probe tip is insulated from the actuator with a wide isolation gap. The device is fabricated by a modified micro electro-discharge machining process which allows electrical isolation within the micromachined structure using an epoxy plug. The apparatus may be used to measure changes in the external surface potential of a microfluidic channel as a function of varying pH of liquid inside the channel. The apparatus also may be used to map embedded charge in a thin layer on a substrate, showing it to be suitable for monitoring microelectronics manufacturing processes.

摘要： A micromachined thermal probe has a substrate with a surface and an edge, and at least one flexible probe body formed on the substrate that includes a cantilever beam section that extends from a proximal end outwardly to a distal end. A pair of conductors in the probe body extend to a junction at the distal end at which is formed a probe tip. Current passed through the conductors to the junction heats the probe tip, with changes in the effective probe resistance occurring as the probe tip is scanned over a sample with different thermal conductivities at different positions. A second flexible probe body may be mounted to the substrate and constructed similarly to the first probe body to act as a reference probe to allow compensation of the first probe. The probe body may be formed of layers of flexible polymer joined together over pairs of conductors, which is bent back onto itself and secured together at a proximal end of the cantilever beam.

摘要： This invention addresses a contact mode hybrid scanning system (HSS), which can be used for measuring topography. The system consists of a cantilever or a cantilever array, a scanning stage, a light source, and instrumentation to synchronize and control the individual components. Detection of the cantilever's movement is achieved by directly measuring the change in disposition of the cantilever including its height, rotation at one or more points on the cantilever thereby providing a partial three-dimensional reconstruction without the need for actuating the cantilever. This is achieved by employing a displacement meter such as a triangulation meter or a confocal meter.
