Abstract: Reusable interfaces and methods for photosensitive device testing are disclosed. The reusable interface includes a removable lid, an opening, a bed configured to hold one or more photosensitive devices. The electrically conductive contacts are configured to interface with the one or more photosensitive devices.

Abstract: A yield and failure analysis system having composite wafermaps provides the ability to view numerous lots on a single screen, identifying the semiconductor manufacturing process, which caused wafer failures and the associated malfunctioning equipment. A wafer inspection instrumentation (28) probes each wafer within a given lot and applies a series of tests. Wafer defect data is stored in a first relational database (46) for compiling a composite wafermap for each lot. Collected wafer defect data is converted into a FFT signature. Present wafer defect data is compared with stored converted wafer defect data patterns to generate correlation coefficients. When the correlation coefficients are within a predetermined range, the converted wafer defect data pattern is stored in the second relational database (47). Data may be accessed from both databases by a user interface (44), enabling the user to analyze data in real time and generate reports.

Abstract: A method involves capturing visual indicia as a digital image, isolating the visual indicia on the digital image, converting the visual indicia to image primitives, identifying and presenting the visual indicia. An apparatus contains a camera for capturing a visual image, a video-to-digital converter, and a computer with a processor, appropriate memory, and software.
