Patent number: 10718931Abstract: A confocal inspection system can optically characterize a sample. An objective lens, or separate incident and return lenses, can deliver incident light from a light source to the sample, and can collect light from the sample. Confocal optics can direct the collected light onto a detector. The system can average the incident light over multiple locations at the sample, for example, by scanning the incident light with a pivotable mirror in the incident and return optical paths, or by illuminating and collecting with multiple spaced-apart confocal apertures. The system can average the collected light, for example, by directing the collected light onto a single-pixel detector, or by directing the collected light onto a multi-pixel detector and averaging the pixel output signals to form a single electronic signal. Averaging the incident and/or return light can be advantageous for structured or inhomogeneous samples.Type: GrantFiled: December 22, 2015Date of Patent: July 21, 2020Assignee: Apple Inc.Inventors: Mark Alan Arbore, Matthew A.

Patent number: 10705435Abstract: Two pairs of alignment targets (one aligned, one misaligned by a bias distance) are formed on different masks to produce a first pair of conjugated interference patterns. Other pairs of alignment targets are also formed on the masks to produce a second pair of conjugated interference patterns that are inverted the first. Misalignment of the dark and light regions of the first interference patterns and the second interference patterns in both pairs of conjugated interference patterns is determined when patterns formed using the masks are overlaid. A magnification factor (of the interference pattern misalignment to the target misalignment) is calculated as a ratio of the difference of misalignment of the relatively dark and relatively light regions in the pairs of interference patterns, over twice the bias distance. The interference pattern misalignment is divided by the magnification factor to produce a self-referenced and self-calibrated target misalignment amount, which is then output.Type: GrantFiled: January 12, 2018Date of Patent: July 7, 2020Assignee: GLOBALFOUNDRIES INC.Inventors: Dongyue Yang, Xintuo Dai, Dongsuk Park, Minghao Tang, Md Motasim Bellah, Pavan Kumar Chinthamanipeta Sripadarao, Cheuk Wun Wong

Patent number: 10670523Abstract: Techniques are disclosed for particulate matter (PM) measurement in a medium (such as air) using flat-top intensity laser sheet beam generation. The techniques for generating the laser sheet beam may include nonspecialized optical elements (e.g., aspherical, spherical, biconvex, and/or cylindrical lenses) that are cost-effective, reduce the overall footprint of the system, and also provide for relatively increased power efficiencies compared to conventional techniques. The PM measurement system may use the laser sheet beam generated in combination with a medium flow channel to pass the medium through the laser sheet beam, thereby causing particulates within the medium to scatter light, which can be detected using a light sensor (e.g., a photodetector). The scattered light signals can then be analyzed to match them with corresponding particulate sizes and the amount of signals per particulate size can also be determined to measure the size and count of particulates within the medium.Type: GrantFiled: April 19, 2016Date of Patent: June 2, 2020Assignee: INTEL CORPORATIONInventors: Tolga Acikalin, Shengbo Xu, Melissa A.
