  • Patent number: 10488328
    Abstract: An imaging system uses polarized light to illuminate the target and then uses a polarization filter to remove the light that is reflected from the target without modification. The target can include one or more anisotropic objects that scatter the light and alter the polarization state of the reflected light and causing it to be selectively transmitted to the imaging device which can record the transmitted light through the filter. The illuminating light can be circularly polarized and the filter can remove the circularly polarized light. The target can include asymmetric nanoparticles, such as nanorods that alter the amplitude or phase of the scattered light enabling pass through the filter to be detected by the imaging device.

  • Publication number: 20190339268
    Abstract: Herein is described kinetic assay, in which individual binding events are detected and monitored during sample incubation. This method uses interferometric reflectance imaging to detect thousands of individual binding events across a multiplex solid phase sensor with a large area. A dynamic tracking procedure is used to measure the duration of each event. From this, the total rates of binding and de-binding as well as the distribution of binding event durations are determined. Systems and components for performing the kinetic assay are also described.

  • Patent number: 10282833
    Abstract: Optical verification testing of an IC includes obtaining images of the IC by, for each image: (i) illuminating the IC with excitation light, wherein the excitation light corresponds to a respective specific optical excitation of a predefined spectrum of optical excitations (e.g., wavelength spectrum); and (ii) detecting scattered light from the IC in response to the specific optical excitation. For each of a set of sub-regions of the images, the respective sub-region is mapped to at least one of (i) a specific sub-unit of a predefined set of sub-units (e.g., gates) of the IC and (ii) a null result, thereby creating a representation of a detected layout of the IC as an arrangement of the sub-units. The representation can be used to verify that an as-fabricated layout is consistent with an as-designed layout, to detect unauthorized modifications of the IC structure.

  • Publication number: 20160313395
    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: 7501303
    Abstract: A silicon wafer having a distributed Bragg reflector buried within it. The buried reflector provides a high efficiency, readily and accurately manufactured reflector with a body of silicon. A photodetector using the buried layer to form a resonant cavity enhancement of the silicon's basic quantum efficiencies and selectivity is provided. The DBR is created by bonding of two or more substrates together at a silicon oxide interface or an oxide-oxide interface. In the former, an hydrogen implant is used to cleave silicon just above the bond line. In the latter, the bonding is at the oxide layers.

  • Publication number: 20080220440
    Abstract: A system for interferometrically detecting the present of bound material using a wave propagating waveguide and the influence on propagation time of bound material in the proximity of the waveguide. The waveguide layer thickness and the radiation wavelength ? are selected so that the effects on phase difference between the two radiations applied in the beam are minimal in the region directly adjacent the surface of the waveguide, so as to unmask the influence of the more distant bound materials.
