Inspection method and apparatus for the inspection of either random or repeating patterns

InactiveUS6021214AHighest-performance and most flexibleMore precisionImage enhancementImage analysisFrequency domainLow complexity
The present invention is a hybrid technique for finding defects on digitized device images using a combination of spatial domain and frequency domain techniques. The two dimensional spectra of two images are found using Fourier like transforms. Any strong harmonics in the spectra are removed, using the same spectral filter on both spectra. The images are then aligned, transformed back to the spatial domain, and subtracted. The resulting spectrally-filtered difference image is thresholded and analyzed for defects. Use of the hybrid technique of the present invention to process digitized images results in the highest-performance and most flexible defect detection system. It is the best performer on both array and random devices, and it can cope with problems such as shading variations and the dark-bright problem that no other technique can address. The hybrid technique of the present invention also uses frequency domain techniques to align the images with fewer errors than spatial domain techniques of similar or lesser complexity. Further, the relative offsets of the pairs of images are determined by frequency domain techniques--and this method may be the most accurate and the least expensive.

Printed circuit board with embedded capacitors therein, and process for manufacturing the same

Disclosed herein are a printed circuit board with embedded capacitors therein and a process for manufacturing the printed circuit board. The embedded capacitors are formed by applying a photosensitive insulating resin to a printed circuit board inner layer, and applying a high dielectric polymer capacitor paste thereto. The process for manufacturing a printed circuit board with embedded capacitors therein comprises the steps of: i) laminating photoresist dry films to a copper clad FR-4, exposing to light and developing the dry films, and etching copper foils of the copper clad FR-4 to form bottom electrodes for forming capacitors; ii) applying a photosensitive insulating resin to the surfaces of the bottom electrodes, and exposing to light and developing to etch the photosensitive insulating resin; iii) applying a capacitor paste to the etched regions and curing the capacitor paste; iv) plating the upper regions of the cured capacitor paste and the photosensitive insulating resin using an electroless copper plating process to form copper foil layers for top electrodes; v) laminating photosensitive dry films to the copper foil layers for top electrodes, and exposing to light and developing the photosensitive dry films to etch regions of the dry films except for the copper foil layers where the top electrodes are to be formed; and vi) etching the regions of the dry films except for the copper foil layers where the top electrodes are to be formed, and the dry films formed on the top electrodes are removed so that the capacitor paste is discretely positioned between the top electrodes and the bottom electrodes to form discrete capacitors.

Method for Implementing and Integrating Biometric Markers, Identification, Real-Time Transaction Monitoring with Fraud Detection and Anti-Money Laundering Predictive Modeling Systems

A method for implementing and integrating biometrical markers, identification, real-time transaction monitoring with fraud detection and anti-money laundering predictive modeling systems as the means of identifying, measuring, detecting and reporting the importance assigned to each member of a population of transactions coupled with images of participants whereby a relationship exists, or groups of relationships, by and between the transactions and the persons identified in the images and/or being affected by at least one suspicious activity factor, transaction or pattern. According to the method, an image is captured and attached to a financial transaction. An identifier is assigned to each member of the image population of persons making transactions for the benefit of one or more financial accounts. The image is cross-referenced against a cloud-based relational database of identified images, known associate persons per images and notations to purported activities and potential risk factors. The cloud-based relational database stores the shared information with subscribers cooperating in the uploading, updating and notating to the identifier record.

Demand-based generation of symbolic information

A human-oriented object programming system (HOOPS) and its debugger provide an interactive and dynamic modeling system to assist in the incremental generation of symbolic information of computer programs that facilitates the development of complex computer programs such as operating systems and large applications with graphic user interfaces (GUIs). A program is modeled as a collection of units called components. A component represents a single compilable language element such as a class or a function. One major functionality built in HOOPS is the debugger, using symbolic properties. The database stores the components and properties. The debugger, using a GUI, displays to the user the execution state of the program. To display the execution state in terms of the programmer's source code, the debugger demands retrieval and/or generation of the symbolic properties of the program. The compiler, which is responsible for calculating the dependencies associated with a component, uses those dependencies to generate the information stored in symbolic properties. The debugger matches versions of source and object code and retrieves source code configuration as needed. Symbolic properties that are stored in the database can be removed to reduce database and disk memory usage; they can be later reconstructed using the same method of demand-based generation of symbolic information.

Method for manufacturing semiconductor device

When single crystal semiconductor layers are transposed from a single crystal semiconductor substrate (a bond wafer), the single crystal semiconductor substrate is etched selectively (this step is also referred to as groove processing), and a plurality of single crystal semiconductor layers, which are being divided in size of manufactured semiconductor elements, are transposed to a different substrate (a base substrate). Thus, a plurality of island-shaped single crystal semiconductor layers (SOI layers) can be formed over the base substrate. Further, etching is performed on the single crystal semiconductor layers formed over the base substrate, and the shapes of the SOI layers are controlled precisely by being processed and modified.

Measuring differential group delay in an optical fiber connection

The differential group delay is measured in an optical fiber connection for an optical signal undergoing a phase modulation BPSK or DPSK by a digital signal at a given rate. A polarization controller at an emerging end of the connection scans polarization states of the modulated optical signal. An emulator iteratively introduces an additional delay in the modulated optical signal emerging from the connection and combines the delayed modulated optical signal and the non delayed modulated optical signal which are both polarized along two orthogonal axes into a resulting optical signal. A polarization controller and a fixed polarizer select a polarization state in the resulting optical signal along one of bisecting lines of the orthogonal axes into a linearly polarized signal. An eye diagram or a spectrum of the polarized signal is acquired by a digital oscilloscope or an optical spectrum analyzer to determine the differential group delay.
