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.

Patent number: 7810379Abstract: A microelectromechanical (MEM) device per the present invention comprises a semiconductor wafer—typically an SOI wafer, a substrate, and a high temperature bond which bonds the wafer to the substrate to form a composite structure. Portions of the composite structure are patterned and etched to define stationary and movable MEM elements, with the movable elements being mechanically coupled to the stationary elements. The high temperature bond is preferably a mechanical bond, with the wafer and substrate having respective bonding pads which are aligned and mechanically connected to form a thermocompression bond to effect the bonding. A metallization layer is typically deposited on the composite structure and patterned to provide electrical interconnections for the device. The metallization layer preferably comprises a conductive refractory material such as platinum to withstand high temperature environments.Type: GrantFiled: August 30, 2007Date of Patent: October 12, 2010Assignee: Rockwell Scientific Licensing LLCInventors: Jeffrey F.
