    Abstract: A method for fabricating a nozzle of microchip-based electrospray device is disclosed. The method includes using a primary mask to accurately define the nozzle feature including the annulus and the through hole of the electrospray device. A secondary masking step is conducted to pattern the through channel (typical the photoresist would serve as the secondary mask), followed by the defining and etching of the primary mask containing the full nozzle feature. The secondary mask serves to selectively mask given areas of the primary mask for subsequent etching. The through hole feature of the secondary mask aligns over the already patterned primary mask through channel, except that the secondary mask contains a slightly larger through channel diameter. This serves to mask off the annulus, but allowing the silicon through channel to be exposed for etching.

    Abstract: A MEMS probe and manufacturing method thereof are provided. The method is mainly to form connected first-level, second-level, and third-level pin grooves on both sides of the silicon substrate through an etching process, followed by two electroplating processes to deposit nickel-cobalt-phosphorus alloy in the first-level pin groove to form the tip of the microprobe, and to deposit nickel-cobalt alloy in the second-level pin groove and the third-level pin to form the pin head and pin arm, thereby forming a three-level microprobe. A circuit substrate made of ceramic material is disposed with at least one window, the surface of the circuit substrate adjacent to the window is provided with a plurality of circuit pads, and the circuit substrate is abutted to the pin arm of the microprobe. The silicon substrate is then removed, to form a plurality of cantilever microprobes made of nickel-cobalt-phosphorus alloy and nickel-cobalt alloy on the circuit substrate.
