The crack deflecting scribe seal includes continuous metal layers and continuous contacts and continuous vias between the continuous metal layers. The continuous metal layers do not extend past the continuous contacts and continuous vias. The continuous contacts and continuous vias are recessed from edges of the underlying continuous metal layers on the scribeline side of the scribe seal, providing an angled outer surface on the scribe seal which may desirably terminate crack propagation or deflect crack propagation upward to a top surface of the scribeline or the crack deflecting scribe seal.

Abstract: The present invention provides, in one embodiment, a method (100) of manufacturing a semiconductor device. A conventionally formed reticle is positioned over a resist located on a substrate (110). A radiation path through the reticle and a window assembly located between a radiation source and resist (120), is considered. It is determined whether or not the radiation would expose a predefined blocking area of the resist within the exposure zone (130). If the radiation would expose a blocking area, then the window assembly is configured to prevent radiation from exposing the blocking area in the exposure zone (140). Other embodiments include a window assembly (300) and system (400) to facilitate manufacturing of the semiconductor device according to the method (100).

Abstract: An x-ray confocal defect detection system comprises an x-ray source, a confocal component, and defect detectors and operates on a target portion of a semiconductor device. The x-ray source generates x-ray energy. The semiconductor device includes a plurality of formed layers. The target portion is a selected layer or portion of the plurality of formed layers. At least a portion of the x-ray is transmitted through the semiconductor device as transmitted x-ray. The confocal component receives the transmitted x-ray and passes target x-ray intensity from the target portion of the transmitted x-ray energy. Detectors receive the target x-ray from the confocal component from which defect analysis can be performed.

Abstract: A hydrogen passivated photovoltaic device such as a solar cell comprises a lattice mismatched substrate such as Ge or Si, and a hydrogen passivated heteroepitaxial layer such as InP grown on the substrate. The hydrogen passivated heteroepitaxial III-V photovoltaic device is produced by exposing a sample of a heteroepitaxial III-V material grown on a lattice-mismatched substrate to reactive hydrogen species at elevated temperatures. Reactive hydrogen forms bonds with dangling bonds along dislocations defined in the sample. The electrical activity in the dislocations is passivated as a result of the hydrogenation process.
