Abstract: A method of forming an integrated circuit structure on a chip includes extracting an active pattern including a diffusion region; enlarging the active pattern to form a dummy-forbidden region having a first edge and a second edge perpendicular to each other; and adding stress-blocking dummy diffusion regions throughout the chip, which includes adding a first stress-blocking dummy diffusion region adjacent and substantially parallel to the first edge of the dummy-forbidden region; and adding a second stress-blocking dummy diffusion region adjacent and substantially parallel to the second edge of the dummy-forbidden region. The method further includes, after the step of adding the stress-blocking dummy diffusion regions throughout the chip, adding general dummy diffusion regions into remaining spacings of the chip.

Abstract: The present invention relates to a single-stage zero-current switching driving circuit for ultrasonic motor, which comprises: a buck-boost converter and a zero-current switching resonant inverter. The driving circuit according to the present invention integrates the buck-boost converter and the resonant inverter into a single-stage structure, so that the buck-boost converter and the resonant inverter share an active switch and a trigger signal, and therefore, the circuit is simplified and the loss caused by stage switching is reduced. Moreover, the buck-boost converter operates in a discontinuous-conduction mode (DCM), which allows the circuit to have high power factor, and enables the active switch to be capable of zero-current switching (ZCS), so that the loss caused by switching is largely reduced. In the driving circuit according to the present invention, there's no interaction of power between the buck-boost converter and the resonant inverter, so that the two circuits can be analyzed individually.

Abstract: A method for transferring inorganic oxide nanoparticles from aqueous phase to organic phase. A modifier is used to change the surface polarity of inorganic oxide nanoparticles, followed by using proper solvents to transfer the modified inorganic oxide nanoparticles form aqueous phase to organic phase. The organic dispersion of modified inorganic oxide nanoparticles can be combined with a polymer to provide a polymer composite with the nanoparticles uniformly dispersed therein.

Abstract: A method for dummy metal and dummy via insertion is provided. In one embodiment, dummy metals are inserted using a place and route tool, where the place and route tool has timing-awareness. Then, dummy vias arrays are inserted inside an overlap area of dummy metals using a design-rule-checking utility. Fine-grained dummy vias arrays are inserted in available space far away from main patterns. The dummy-patterns resulting from the inserted dummy vias are compressed using the design-rule-checking utility to reduce the size of a graphic data system file generated from the integrated circuit design. The dummy vias can be inserted with relaxed via spacing rules. The dummy metals are inserted with a constant line-end spacing between them for better process control and the maximum length of the dummy metal can be limited for smaller coupling effects. The dummy vias can have various sizes and a square or rectangular shape.

Abstract: A video analysis technique includes correlating frames from a processed video with frames from a pre-processed, original video. A linear approximation of a relationship between the correlated frames is determined. A disclosed example includes determining a linear approximation that maximizes the number of processed video frames that fit into the linear approximation. The linear approximation and whether any frames do not fit within the linear approximation is then used to provide quality information for analyzing a quality of the processed video.

Abstract: An exemplary method of welding electronic components on PCBs is disclosed. Firstly, a metal tray including a number of supporting areas is provided. At least one through hole is formed in each of the supporting areas. Secondly, solder pastes are applied onto welding pads of PCBs. Thirdly, electronic components are mounted on the welding pads. Fourthly, PCBs are placed on the metal tray in a manner that each printed circuit board is placed in a corresponding supporting area and the welding pads being above the through hole. Finally, the solder pastes are heated to weld the electronic components on the printed circuit board. By doing so, the heat can pass through the through holes in each supporting area directly and fully melt the solder paste. As a result, welding defects can be reduced.

In addition, the process can translate the high level programming language into a unified format for representation, and the AD can benefit simulation and requirement in a following HDL translation.
