After a film layer 6 formed from a die attach film 4 and a UV tape 5 has been provided as a mask on a semiconductor wafer 1, boundary trenches 7 for partitioning semiconductor elements 2 formed on a circuit pattern formation surface 1a are formed in the film layer 6, thereby making a surface 1c of a semiconductor wafer 1 exposed. The exposed surface 1c of the semiconductor wafer 1 in the boundary trenches 7 is etched by means of plasma of a fluorine-based gas, and the semiconductor wafer 1 is sliced into semiconductor chips 1′ along the boundary trenches 7.

An apparatus and method for detecting and correcting for physical misalignments of a pair of digital cameras creating a composite, three dimensional (3D) image of a target. The method involves using the distances from each of a pair of digital cameras to a target and determining correction offset values for one or the other of the images produced in the digital cameras to achieve pixel-to-pixel coincidence of the two images. The correction offset values are calculated and performed in real time and eliminate the need to physically remove a common platform on which the cameras are mounted from a mobile platform or other support structure, and to transport same to a laboratory environment for the needed calibration. Advantageously, the correction values are generated electronically and applied in real time as any misalignment between the cameras is sensed.

There is provided a flexible semiconductor device. The flexible semiconductor device of the present invention comprises a metal layer comprising a gate electrode, a source electrode and a drain electrode; a metal oxide film made from a metal which constitutes the metal layer and formed over a surface region of the metal layer; and a semiconductor layer formed above the gate electrode via the metal oxide film. In the flexible semiconductor device, uncovered portions, each of which is not covered with the metal oxide film, are locally formed in the surface region of the metal layer; and also electrical connections are formed between the source electrode and the semiconductor layer and between the drain electrode and the semiconductor layer via the uncovered portions.

A NAND flash memory device includes a plurality of continuous conductors disposed on a common level of a multilayer substrate, the plurality of continuous conductors including respective conductive lines extending in parallel along a first direction, respective contact pads disposed at ends of the respective conductive lines and respective conductive dummy lines extending in parallel from the contact pads along a second direction.

A portal is provided with a detector for detecting trace amounts of substances of interest that may be retained on the surface or interior of a vehicular subject. The portal relies upon the continuous process by which microscopic flakes of dust, dirt, pollen, and other surface and interior contaminants as well as adsorbed analyte media and analyte vapors continuously separate from the surface of vehicular subjects and escape from the interior of vehicular subjects. The portal further leverages the existence of a vehicular thermal plume consisting of a layer of warm air adjacent to the vehicular subject. The warm air rises in the cooler surrounding air and transports the microscopic flakes of surface contaminants, desorbed analyte, and analyte vapors upwardly. The portal capitalizes on this phenomenon by providing at least a partial enclosure with a funnel-shaped collector above the vehicular subject. A low speed flow of relatively dense cool air may be introduced into the portal to buoyantly lift the warmer air of the vehicular thermal plume upwardly. The air stream defined by the vehicular thermal plume and the contaminant particles, analyte media, and analyte vapors therein moves to a trap in the funnel-shaped collector above the portal. The trap cooperates with a detector for detecting the presence of molecules of interest.

A method of forming fine patterns of a semiconductor device, in which a plurality of conductive lines formed in a cell array region are integrally formed with contact pads for connecting the conductive lines to a peripheral circuit. In this method, a plurality of mold mask patterns, each including a first portion extending in a first direction and a second portion which is integrally formed with the first portion and extends in a second direction, are formed within a cell block on a substrate comprising a film which is to be etched. A first mask layer covering sidewalls and an upper surface of each of the plurality of mold mask patterns is formed on the substrate. First mask patterns are formed by partially removing the first mask layer so that a first area of the first mask layer remains and a second area of the first mask layer is removed. The first area of the first mask layer covers sidewalls of adjacent mold mask patterns from among the plurality of mold mask patterns by being located between the adjacent mold mask patterns, and the second area of the first mask layer covers portions of the sidewalls of the plurality of mold mask patterns, the portions corresponding to an outermost sidewall of a mold mask pattern block.

When a sintered body of ceramic is shot-blasted at normal temperatures to plastically deform the crystal structure of the shot-blasted surface to apply residual stress and is heat-treated to recrystallize fine cracks, dislocated cells in the grain boundary are formed, crystals are finely divided, and the fracture toughness is significantly improved. When the sintered body of ceramic is a thin product, an effective toughening can be attained by shot blasting both the front and back sides. After heat treatment, mechanical strength is significantly improved by removing a part of the modified surface layer by an abrasion treatment.

A shift knob structure includes a shift knob body and a cover member. Movement of the shift knob body in a direction of shaft axis is restricted by a securing member supported by a support part of the shift knob body being locked by a locking groove in the shift shaft. When the cover member is rotated relative to the shaft knob body, the securing member is deformed radially outward and the securing member is unlocked from the locking groove in the shift shaft so that the shift knob body can be removed from the shift shaft.

A large-sized transportable projection screen comprising an any-shaped fillable hollow body, which is embodied in the form of a structure consisting of fillable tubes. The aim is to develop a large-sized transportable projection screen exhibiting an increased stability and making it possible to obtain an improved projection at daylight.
