  • Publication number: 20120273781
    Abstract: A method and device are provided for the RF characterization of nanostructures and high impedance devices. A two-terminal electronic nanostructure device is fabricated by dividing a length of a nanostructure into a plurality of shorter, identical nanostructures using a plurality of finger electrodes electrically connected in parallel. The nanostructure may include a single walled carbon nanotube subdivided into shorter identical copies of a metallic nanotube segment by situating multiple finger electrodes along the length of the single walled carbon nanotube. Each of the subdivided shorter nanotube segments are connected in parallel. This arrangement allows for close impedance matching to radio frequency (RF) systems, and serves as an important technique in understanding and characterizing metallic (and even semiconducting) nanotubes at RF and microwave frequencies.

  • Publication number: 20120276665
    Abstract: The present disclosure provides methods and apparatus that enable characterization of an electrical property of a semiconductor specimen, e.g., dopant concentration of a near-surface region of the specimen. In exemplary method, a target depth for measurement is selected. This thickness may, for example, correspond to a nominal production thickness of a thin active device region of the specimen. A light is adjusted to an intensity selected to characterize a target region of the specimen having a thickness no greater than the target depth and a surface of the specimen is illuminated with the light. An AC voltage signal induced in the specimen by the light is measured and this AC voltage may be used to quantify an aspect of the electrical property, e.g., to determine dopant concentration, of the target region.

  • Patent number: 8206997
    Abstract: A probe having a sufficient height is manufactured by selectively depositing, over the main surface of a wafer, a copper film in a region in which a metal film is to be formed and a region which will be outside an adhesion ring when a probe card is fabricated; forming the metal film, polyimide film, interconnect, another polyimide film, another interconnect and a further polyimide film; and then removing the wafer and copper film. According to the present invention, when probe testing is performed using a prober (thin film probe) having the probe formed in the above-described manner while utilizing the manufacturing technology of semiconductor integrated circuit devices, it is possible to prevent breakage of the prober and a wafer to be tested.

    Abstract: Embodiments of the present invention provide a semiconductor sensor reliability system and method. Specifically, the present invention provides in-situ positioning of a reliability sensor (hereinafter sensors) within each functional block, as well as at critical locations, of a semiconductor system. The quantity and location of the sensors are optimized to have maximum sensitivity to known process variations. In general, the sensor models a behavior (e.g., aging process) of the location (e.g., functional block) in which it is positioned and comprises a plurality of stages connected as a network and a self-digitizer. Each sensor has a mode selection input for selecting a mode thereof and an operational trigger input for enabling the sensor to model the behavior. The model selection input and operation trigger enable the sensor to have an operational mode in which the plurality of sensors are subject to an aging process, as well as a measurement mode in which an age of the plurality of sensors is outputted.

  • Publication number: 20120138800
    Abstract: A radiation sensor includes an integrated circuit radiation sensor chip (1A) including first (7) and second (8) thermopile junctions connected in series to form a thermopile (7,8) within a dielectric stack (3). The first thermopile junction (7) is insulated from a substrate (2) of the chip. A resistive heater (6) in the dielectric stack for heating the first thermopile junction is coupled to a calibration circuit (67) for calibrating responsivity of the thermopile (7,8). The calibration circuit causes a current flow in the heater and multiplies the current by a resulting voltage across the heater to determine power dissipation. A resulting thermoelectric voltage (Vout) of the thermopile (7,8) is divided by the power to provide the responsivity of the sensor.
