    Abstract: PROBLEM TO BE SOLVED: To provide a chemical analytical system of large capacity easy to be reproduced and allowing mass production. SOLUTION: The chemical analytical system includes the first substrate having a main face, the second substrate joined or attached thereto, a liquid chromatography system integrated thereto, and constituted to receive and treat an analytical liquid to be discharged, and a monolithic electrospray device having an inlet orifice located in a injection side, a nozzle located on a discharge face opposite to the injection side, a channel extended penetrated continuously through a monolithic device, and communicated with the inlet orifice and the nozzle, and an area recessed from the discharge face to surround the nozzle. The monolithic device is integrated on the first substrate, the injection side is constituted to receive the treated liquid from the liquid chromatography system, and the main face is constituted to distribute the liquid by electrospraying the liquid.

    Abstract: A micromechanical capacitive accelerometer is provided from a single silicon wafer. The basic structure of the micromechanical accelerometer is etched in the wafer to form a released portion in the substrate, and the released and remaining portions of the substrate are coated with metal under conditio ns sufficient to form a micromechanical capacitive accelerometer. The substrate is preferably etched using reactive-ion etching for at least the first etch ste p in the process that forms the basic structure, although in another preferred embodiment, all etching is reactive-ion etching. The accelerometer also may comprise a signal-conditioned accelerometer wherein signal-conditioning circuitry is provided on the same wafer from which the accelerometer is formed, and VLSI electronics may be integrated on the same wafer from which the accelerometer is formed. The micromechanical capacitive accelerometer can be used for airbag deployment, active suspension control, active steerin g control, anti-lock braking, and other control systems requiring acceleromete rs having high sensitivity, extreme accuracy and resistance to out of plane forces.

    Abstract: Three fundamental and three derived aspects of the present invention are disclosed. The three fundamental aspects each disclose a process sequence th at may be integrated in a full process. The first aspect, designated as "latent masking", defines a mask in a persistent material like silicon oxide that is held abeyant after definition while intervening processing operations are performed. The laten oxide pattern is then used to mask an etch. The second aspect, designated as "simultaneous multi-level etching (SMILE)", provides a process sequence wherein a first pattern may be given an advanced start relative to a second pattern in etching into an underlying material, such that the first pattern may be etched deeper, shallower, or to the same depth as the second pattern. The third aspect, designated as "delayed LOCOS", provides a means of defining a contact hole pattern at one stage of a process, then using the defined pattern at a later stage to open the contact holes. The fourth aspect provides a process sequen ce that incorporates all three fundamental aspects to fabricate an integrated liquid chromatography (LC)/electrospray ionization (ESI) device. The fifth aspect provides a process sequence that incorporates two of the fundamental aspects to fabricatean ESI device. The sixth aspect provides a process sequence that incorporates two of the fundamental aspects to fabricate an LC device. The process improvements described provide increased manufacturing yield and design latitude in comparison to previously disclosed methods of fabrication.

    Abstract: An electrospray device, a liquid chromatography device and an electrospray-liquid chromatography system are disclosed. The electrospray device comprises a substrate defining a channel between an entrance orifice on an injection surface and an exit orifice on an ejection surface, a nozzle defined by a portion recessed from the ejection surface surrounding the exit orifice, and an electrode for application of an electric potential to the substrate to optimize and generate an electrospray; and, optionally, additional electrode(s) to further modify the electrospray. The liquid chromatography device comprises a separation substrate defining an introduction channel between an entrance orifice and a reservoir and a separation channel between the reservoir and an exit orifice, the separation channel being populated with separation posts perpendicular to the fluid flow; a cover substrate bonded to the separation substrate to enclose the reservoir and the separation channel adjacent the cover substrate; and, optionally, electrode(s) for application of a electric potential to the fluid. The exit orifice of the liquid chromatography device may be homogeneously interfaced with the entrance orifice of the electrospray device to form an integrated single system. An array of multiple systems may be fabricated in a single monolithic chip for rapid sequential fluid processing and generation of electrospray for subsequent analysis, such as by positioning the exit orifices of the electrospray devices near the sampling orifice of a mass spectrometer.
