  • Patent number: 11810746
    Abstract: An ion source having an extraction plate with a variable thickness is disclosed. The extraction plate has a protrusion on its interior or exterior surface proximate the extraction aperture. The protrusion increases the thickness of the extraction aperture in certain regions. This increases the loss area in those regions, which serves as a sink for ions and electrons. In this way, the plasma density is decreased more significantly in the regions where the extraction aperture has a greater thickness. The shape of the protrusion may be modified to achieve the desired plasma uniformity. Thus, it may be possible to create an extracted ion beam having a more uniform ion density. In some tests, the uniformity of the beam current along the width direction was improved by between 20% and 50%.

  • Patent number: 11402429
    Abstract: A precise optical technique for measuring electronic transport properties in semiconductors is disclosed. Using tightly focused laser beams in a photo-modulated reflectance system, the modulated reflectance signal is measured as a function of the longitudinal (Z) displacement of the sample from focus. The modulated component of the reflected probe beam is a Gaussian beam with its profile determined by the focal parameters and the complex diffusion length. The reflected probe beam is collected and input to the detector, thereby integrating over the radial profile of the beam. This results in a simple analytic expression for the Z dependence of the signal in terms of the complex diffusion length. Best fit values for the diffusion length and recombination lifetime are obtained via a nonlinear regression analysis. The output diffusion lengths and recombination lifetimes and their estimated uncertainties may then be used to evaluate various transport properties and their associated uncertainties.

  • Patent number: 10678971
    Abstract: A system, a computer program product, and method for physically fabricating an electronic circuit using design space exploration as part of a design process is described. The method begins with defining a plurality of design space parameters to be tuned along with parameter ranges for each of the plurality of design space parameters. Next an output target to be optimized is defined. A series of one or more test mask shapes are generated to appear on a photo mask using the plurality of design space parameters. A simulation of a post lithography or etch on the series of one or more test mask shapes is performed to produce simulation output values. Next, the simulation output values and corresponding design space parameters are fed into to a Bayesian inference algorithm for assessment and identification of a next combination of design space parameters to investigate.

  • Patent number: 10627549
    Abstract: Substrates with lenses having lenses disposed therein are aligned with high accuracy. A stacked lens structure has a configuration in which substrates with lenses having a lens disposed on an inner side of a through-hole formed in the substrate are direct-bonded and stacked based on an alignment mark. The alignment mark is formed simultaneously with the through-hole. The present technique can be applied to a camera module or the like in which a stacked lens structure in which at least three substrates with lenses including first to third substrates with lenses which are substrates with lenses in which a through-hole is formed in the substrate and a lens is formed on an inner side of the through-hole is integrated with a light receiving element, for example.

  • Patent number: 10514363
    Abstract: Methods and systems may be configured to integrate data from fixed nondestructive inspection sensors positioned on a test specimen and data from laser ultrasound scans of the test specimen, in order to monitor and track damage and stress indications in the test specimen in real-time during mechanical stress testing of the test specimen. Data from the laser ultrasound scans may identify emergent areas of interest within the test specimen that were not predicted by stress analysis, and further allow for reconfiguration of the test plan in view of the emergent areas of interest, without having the stop the test. Laser ultrasound scans may be performed on the entire test specimen, with high-resolution scans being performed on emergent areas of interest. Thus, stress indications, or stress effects, in the test specimen may be measured, identified, and tracked in real-time (e.g., as growth is propagating) in a test specimen undergoing structural tests.

  • Patent number: 10354929
    Abstract: An optimized measurement recipe is determined by reducing the set of measurement technologies and ranges of machine parameters required to achieve a satisfactory measurement result. The reduction in the set of measurement technologies and ranges of machine parameters is based on available process variation information and spectral sensitivity information associated with an initial measurement model. The process variation information and spectral sensitivity information are used to determine a second measurement model having fewer floating parameters and less correlation among parameters. Subsequent measurement analysis is performed using the second, constrained model and a set of measurement data corresponding to a reduced set of measurement technologies and ranges of machine parameters.

  • Patent number: 9785059
    Abstract: Alignment of layers during manufacture of a multi-layer sample is controlled by applying optical measurements to a measurement site in the sample. The measurement site includes two diffractive structures located one above the other in two different layers, respectively. The optical measurements include at least two measurements with different polarization states of incident light, each measurement including illuminating the measurement site so as to illuminate one of the diffractive structures through the other. The diffraction properties of the measurement site are indicative of a lateral shift between the diffractive structures. The diffraction properties detected are analyzed for the different polarization states of the incident light to determine an existing lateral shift between the layers.
