Publication number: 20100207229Abstract: 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: ApplicationFiled: February 18, 2009Publication date: August 19, 2010Inventors: Jeffrey F.

Publication number: 20100110607Abstract: 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: ApplicationFiled: November 5, 2008Publication date: May 6, 2010Inventors: Jeffrey F.

Patent number: 7328604Abstract: A microelectromechanical (MEM) fluid health sensing device comprises a viscosity sensor which provides an output that varies with the viscosity of a fluid in which it is immersed, and at least one other sensor which provides an output that varies with another predetermined parameter of the fluid. The viscosity sensor is preferably a MEM device fabricated by means of a “deep etch” process. The sensors are preferably integrated together on a common substrate, though they might also be fabricated separately and packaged together to form a hybrid device. A data processing means may be included which receives the sensor outputs and provides one or more outputs indicative of the health of the fluid. Sensor types which may be part of the present device include, for example, a temperature sensor, a MEM electrochemical sensor, a MEM accelerometer, a MEM contact switch lubricity sensor, and/or an inductive metallic wear sensor.Type: GrantFiled: September 22, 2005Date of Patent: February 12, 2008Assignee: Teledyne Licensing, LLCInventors: Jeffrey F.

Patent number: 7329932Abstract: A MEM viscosity sensor comprises a substrate, with first and second support structures affixed to the substrate and spaced-apart. A compliant member is affixed to the support structures such that it is suspended above and can flex vertically with respect to the substrate. The member has a high density of perforations, through which a fluid whose viscosity is to be sensed can flow. The sensor includes a drive means to apply a force to the member, and a sensing means to sense the vertical motion of the member in response to the applied force. The member's perforations ensure that its resistance to motion will be shear in nature, and minimizes sensitivity to particulates. The substrate is also preferably perforated to further reduce non-shear forces and facilitate fluid exchange.Type: GrantFiled: September 12, 2005Date of Patent: February 12, 2008Assignee: Teledyne Licensing, LLCInventors: Jeffrey F.

Patent number: 7287415Abstract: Embodiments of the present invention are directed to a MEM viscosity sensor that is configured to be operated submerged in a liquid. The MEMS viscosity sensor comprises a MEMS variable capacitor comprising a plurality of capacitor plates capable of being submerged in a liquid. An actuator places a driving force on the variable capacitor which causes relative movement between the plates, where the movement creates a shear force between each moving plate and the liquid, which damps the movement of the plate and increases the capacitor's response time to the applied force in accordance with the liquid's viscosity. To determine the actual viscosity of the liquid, a sensor is coupled to the variable capacitor for sensing the response time of the plates as an indicator of the liquid's viscosity.Type: GrantFiled: September 30, 2004Date of Patent: October 30, 2007Assignee: Teledyne Licensing, LLCInventors: Robert L.

Patent number: 6979872Abstract: A MEMS module is provided comprising at least one MEMS device adhesively bonded to a substrate or wafer, such as a CMOS die, carrying pre-processed electronic circuitry. The at least one MEMS device, which may comprise a sensor or an actuator, may thus be integrated with related control, readout/signal conditioning, and/or signal processing circuitry. An example of a method pursuant to the invention comprises the adhesive bonding of a pre-processed electronics substrate or wafer to a layered structure preferably in the form of a silicon-on-insulator (SOI) substrate.

Patent number: 6771081Abstract: Micro-electromechanical (MEM) devices having their fixed and movable members immersed in a liquid medium. Movement is effected by applying a stimulus which creates a force that causes the movable member to move with respect to the fixed member. The movable and fixed members are immersed in a liquid medium having desired characteristics. The liquid is preferably selected to have a viscosity which critically damps the motion of the movable member. The liquid may also be chosen to provide a dielectric constant greater than one, which, where applicable, increases the electrostatic force created for a given drive voltage, and the device's capacitance sensing range, over what they would be in air. The liquid medium might also be used to improve the device's thermal dissipation characteristics, or to provide improved isolation between structures.Type: GrantFiled: August 22, 2002Date of Patent: August 3, 2004Assignee: Rockwell Scientific Licensing, LLCInventors: Robert L.
