  • Patent number: 11312067
    Abstract: An apparatus is disclosed for performing an additive manufacturing operation to form a structure by processing a photopolymer resist material. The apparatus may incorporate a laser for generating a laser beam, and a tunable mask for receiving the laser beam which has an optically dispersive element. The mask splits the laser beam into a plurality of emergent beams each having a subplurality of beamlets of varying or identical intensity, with each beamlet emerging from a unique subsection of illuminated regions of the mask. A collimator collimates at least one of the emergent beams to form a collimated beam. One or more focusing elements focuses the collimated beam into a focused beam which is projected as a focused image plane on or within the resist material. The focused beam simultaneously illuminates a layer of the resist material to process an entire layer in a parallel fashion.

    Abstract: An auto-rotation module having a single-layer neural network on a user device can convert a document image to a monochrome image having black and white pixels and segment the monochrome image into bounding boxes, each bounding box defining a connected segment of black pixels in the monochrome image. The auto-rotation module can determine textual snippets from the bounding boxes and prepare them into input images for the single-layer neural network. The single-layer neural network is trained to process each input image, recognize a correct orientation, and output a set of results for each input image. Each result indicates a probability associated with a particular orientation. The auto-rotation module can examine the results, determine what degree of rotation is needed to achieve a correct orientation of the document image, and automatically rotate the document image by the degree of rotation needed to achieve the correct orientation of the document image.

The method includes: measuring, for a plurality of n different alignment measurement parameters ? and for a plurality of substrates, a position of the alignment marks; determining a positional deviation as the difference between the n alignment mark position measurements and a nominal alignment mark position; grouping the positional deviations into data sets; determining an average data set; subtracting the average data set from the data sets to obtain a plurality of variable data sets; performing a blind source separation method on the variable data sets, thereby decomposing the variable data sets into a set of eigenwafers representing principal components of the variable data sets; and subdividing the set of eigenwafers into a set of mark deformation eigenwafers and a set of substrate deformation eigenwafers.

  • Patent number: 10475179
    Abstract: Methods and apparatus for inspection of electronic parts such as semiconductor wafers, high-density circuit boards, multi-layer substrates, chrome on glass masks, and other fine line products which compensates for reference misalignment. Conductor linewidth and space measurements are performed along the entire length of every conductor to sub-camera pixel, sub-micron accuracy in real time as the part is scanned. Billions of metrology measurements are also performed in real time to sub-micron accuracy. A self-learning automated method to extract measurement values from Computer Aided Design (CAD) files is described. This method automatically determines locations to perform these billons of operations within defined allowed manufacturing tolerances.

  • Patent number: 10445860
    Abstract: A scene presented by a headset is adjusted to correct for distortion from optical errors of an optics block in the headset. To correct for the distortion, the scene is pre-distorted when presented based on previously modeled distortion of the optics block, so distortion from the optics block corrects the pre-distortion. To model the distortion, the headset displays calibration image including features and images of the calibration image are captured from multiple positions. Differences between locations of features in the calibration images and locations of corresponding features in captured images of the calibration image are identified and a distortion correction is determined based on the differences.

  • Patent number: 10408602
    Abstract: Methods are provided, which estimate a quality of a metrology target by calculating a noise metric of its ROI kernels, derived from application of a Fourier filter on the measured kernel with respect to a periodicity of the target's periodic structure(s); and using the calculated noise metric to indicate the target quality. An additional Fourier filter may be applied perpendicularly on the measured kernel with respect to a periodicity of a perpendicular segmentation of the periodic structure(s), and the (2D) noise metric may be derived by application of both Fourier filters. The estimated noise may be analyzed statistically to provide various types of information on the target.

  • Patent number: 10234285
    Abstract: A tiltmeter-integrated two element optical relative alignment monitor provides relative alignment and contact sensing and can provide precise information regarding the nature of physical contact experienced by objects being monitored. A computer monitor can display the information in real time, in an intuitive manner. This system can provide all the information with good resolution in a low-cost, easily installable package for a wide variety of research, high energy physics applications, and industrial uses. A projector unit is mounted on one component containing a diffuse light source, a coded mask, and a lens. The projector is aligned with a camera to receive the focused image. Shifts in the image of the mask indicate relative motion between the camera and the projector unit. A tiltmeter is affixed to either the camera or projector, to distinguish between image shifts due to translational movement and image shifts due to rotation or tilting.

  • Patent number: 10114995
    Abstract: A method and arrangements for estimating one or more dominating orientations (?dom) in at least a part (201; 301) of a digital image (200; 300; 600). Representative angles (?1 . . . ?N) representing angles of gradient vectors (g1 . . . gN) for pixels (1 . . . N) of said at least part are obtained (401). It is further obtained (402) a target number (n) of dominating orientations. It is also obtained (404) a first sum (a) comprising added sine factors based on computed sines. The sines are computed for angles that correspond to said representative angles (?1 . . . ?N) multiplied with two times the target number (n). Further it is obtained (405) a second sum (b) comprising added cosine factors based on computed cosines for the same angles that said sine were computed for. Said one or more dominating orientations (?dom) are then estimated (406) based on the first sum (a), the second sum (b) and the target number (n).
