Patent number: 8472098Abstract: A wafer-level manufacturing method produces stress compensated x-y gimbaled comb-driven MEMS mirror arrays using two SOI wafers and a single carrier wafer. MEMS structures such as comb drives, springs, and optical surfaces are formed by processing front substrate layer surfaces of the SOI wafers, bonding together the processed surfaces, and removing the unprocessed SOI layers to expose second surfaces of the front substrate layers for further wafer-level processing. The bonded SOI wafers are mounted to a surface of the carrier wafer that has been separately processed. Processing wafer surfaces may include formation of a stress compensation layer to counteract physical effects of MEMS mirrors. The method may form multi-layered conductive spring structures for the mirrors, each spring having a first conducting layer for energizing a comb drive, a second conducting layer imparting a restoring force, and an insulating layer between the first and second conducting layers.Type: GrantFiled: September 7, 2010Date of Patent: June 25, 2013Assignee: Teledyne Scientific & Imaging, LLCInventors: Chialun Tsai, Jeffrey F.

Patent number: 8153062Abstract: Electrochemical devices, methods, and systems for detecting and quantifying analytes are disclosed. A chemical detection reagent is locally generated in a test solution by electrochemical reaction of a precursor compound caused to migrate into the test solution from a precursor solution separated from the test solution by a cell separator. This approach provides precise metering of the reagent, via the charge passed, and avoids the need to store a reagent solution that may be chemically unstable. In one embodiment, the starch concentration in a colloidal solution can be measured via spectroscopic detection of a blue complex formed by the interaction of starch with iodine produced, on demand, by electrochemical oxidation of iodide ion. The approach may also be used to characterize certain types of analytes. The invention is amenable to automation and is particularly useful for on-line monitoring of production processes, including the inclusion of feed back loop mechanisms for process control.Type: GrantFiled: March 30, 2007Date of Patent: April 10, 2012Assignee: Teledyne Scientific & Imaging, LLCInventors: Martin W.

Patent number: 8088667Abstract: A fabrication method which forms vertical capacitors in a substrate. The method is preferably an all-dry process, comprising forming a through-substrate via hole in the substrate, depositing a first conductive material layer into the via hole using atomic layer deposition (ALD) such that it is electrically continuous across the length of the via hole, depositing an electrically insulating, continuous and substantially conformal isolation material layer over the first conductive layer using ALD, and depositing a second conductive material layer over the isolation material layer using ALD such that it is electrically continuous across the length of the via hole. The layers are arranged such that they form a vertical capacitor. The present method may be successfully practiced at temperatures of less than 200° C., thereby avoiding damage to circuitry residing on the substrate that might otherwise occur.Type: GrantFiled: November 5, 2008Date of Patent: January 3, 2012Assignee: Teledyne Scientific & Imaging, LLCInventors: Jeffrey F.

Patent number: 8080736Abstract: A foldable microcircuit is initially a planar semiconductor wafer on which circuitry has been formed. The wafer is segmented into a plurality of tiles, and a plurality of hinge mechanisms are coupled between adjacent pairs of tiles such that the segmented wafer can be folded into a desired non-planar configuration having a high fill-factor and small gaps between tiles. The hinge mechanisms can comprise an organic material deposited on the wafer such that it provides mechanical coupling between adjacent tiles, with metal interconnections between tiles formed directly over the organic hinges, or routed between adjacent tiles via compliant bridges. Alternatively, the interconnection traces between tiles can serve as part or all of a hinge mechanism. The foldable microcircuit can be, for example, a CMOS circuit, with the segmented tiles folded to form, for example, a semi-spherical structure arranged to provide a wide FOV photodetector array.Type: GrantFiled: February 18, 2009Date of Patent: December 20, 2011Assignee: Teledyne Scientific & Imaging, LLCInventors: Jeffrey F.

Patent number: 7987714Abstract: A disc resonator gyroscope (DRG) and method of manufacture. The DRG has a surrounding pattern of bond metal having a symmetry related to the symmetry of a resonator device wafer that enables more even dissipation of heat from a resonator device wafer of the DRG during an etching operation. The metal bond frame eliminates or substantially reduces the thermal asymmetry that the resonator device wafer normally experiences when a conventional, square bond frame is used, which in turn can cause geometric asymmetry in the widths of the beams that are etched into the resonator device wafer of the DRG.Type: GrantFiled: October 12, 2007Date of Patent: August 2, 2011Assignee: The Boeing CompanyInventors: Jeffrey F.
