  • Patent number: 10705138
    Abstract: A device testing approach employs optical antennas at test locations of a semiconductor device, usable as either/both radiators or receivers. As a radiator, an antenna responds to localized optical energy at a test location of the device to generate corresponding radiated optical energy that can be sensed and processed by a test system. As a receiver, an antenna receives radiated optical energy as generated by a test system and converts the energy into corresponding localized optical energy for affecting operation of the device. The optical antennas may be formed from metal segments on the same metal layers used for signal interconnections in the device, and thus the disclosed approach can provide enhanced test functionality without burdening the device manufacturing process with additional complexity solely to support testing. The testing approach may be used in different modalities in which the antennas variably act as transmitters, receivers, and reflectors/refractors.

  • Patent number: 9252252
    Abstract: This invention describes a novel electronic device consisting of one—or more—vertically stacked gate-all-around silicon nanowire field effect transistor (SNWFET) with two independent gate electrodes. One of the two gate electrodes, acting on the central section of the transistor channel, controls on/off behavior of the channel. The second gate, acting on the regions in proximity to the source and the drain of the transistor, defines the polarity of the devices, i.e. p or n type. The electric field of the second gate acts either at the interface of the nanowire-to-source/drain region or anywhere in close proximity to the depleted region of the SiNW body, modulating the bending of the Schottky barriers at the contacts, eventually screening one type of charge carrier to pass through the channel of the transistor. This is achieved by controlling the majority carriers passing through the transistor channel by regulating the Schottky barrier thicknesses at the source and drain contacts.

  • Patent number: 9234728
    Abstract: A modular reconnaissance capsule or reconnaissance pod is provided that is suitable for deployment by means of an artillery launching platform, such as a conventional 40 mm grenade launcher or 155 mm cannon wherein a parachute is deployed at a pre-calculated observation altitude, the parachute being designed to yield a sufficiently slow rate of descent to permit live video capture and transmission of images as forward observation information. Alternatively, pods according to the invention may also be air dropped from an aircraft, either piloted or pilotless, thus allowing the aircraft to operate at a safe distance and yet provide close reconnaissance even under a cloud cover. Accurate information about targeting dynamics is made available to the user through commercially available products. The invention complements other reconnaissance methods and provides easy-to-use real-time visual information for a desired area of interest.
