Abstract: An emission map of a circuit to be tested for alterations is obtained by measuring the physical circuit to be tested. An emission map of a reference circuit is obtained by measuring a physical reference circuit or by simulating the emissions expected from the reference circuit. The emission map of the circuit to be tested is compared with the emission map of the reference circuit, to determine presence of alterations in the circuit to be tested, as compared to the reference circuit.

Abstract: A method is provided for designing a mask layout for an integrated circuit that ensures proper functional interaction among circuit features by including functional inter-layer and intra-layer constraints on the wafer. The functional constraints used according to the present invention are applied among the simulated wafer images to ensure proper functional interaction, while relaxing or eliminating the EPE constraints on the location of the wafer images.

Abstract: A method of forming a planar CMOS transistor divides the step of forming the gate layer into a first step of patterning a resist layer with a first portion of the gate layer pattern and then etching the polysilicon with the pattern of the gates. A second step patterns a second resist layer with the image of the gate pads and local interconnect and then etching the polysilicon with the pattern of the gate pads and local interconnect, thereby reducing the number of diffraction and other cross-talk from different exposed areas.

Abstract: Mass-customized parts are identified by encoding part identification information into a multi-dimensional bar code, wherein mass-customization machinery, such as stereolithography apparatus, is used to make the parts with the multi-dimensional bar code embedded therein.

Abstract: An iterative timing analysis is analytically performed before a chip is fabricated, based on a methodology using optical proximity correction techniques for shortening the gate lengths and adjusting metal line widths and proximity distances of critical time sensitive devices. The additional mask is used as a selective trim to form shortened gate lengths or wider metal lines for the selected, predetermined transistors, affecting the threshold voltages and the RC time constants of the selected devices. Marker shapes identify a predetermined subgroup of circuitry that constitutes the devices in the critical timing path. The analysis methodology is repeated as often as needed to improve the timing of the circuit with shortened designed gate lengths and modified RC timing constants until manufacturing limits are reached. A mask is made for the selected critical devices using OPC techniques.

Abstract: A design system for designing complex integrated circuits (ICs), a method of IC design and program product therefor. A layout unit receives a circuit description representing portions in a grid and glyph format. A checking unit checks grid and glyph portions of the design. An elaboration unit generates a target layout from the checked design. A data prep unit prepares the target layout for mask making. A pattern caching unit selectively replaces portions of the design with previously cached results for improved design efficiency.

Abstract: Apparatus and methods for pumping and oxygenating blood are provided that include a gas removal system. An integrated blood processing unit is provided in which a gas removal/blood filter, pump and blood oxygenation element are mounted within a common housing. The gas removal system includes a sensor mounted on the housing to sense the presence of gas, and a valve is operably coupled to the sensor to evacuate gas from the system when the sensor detects an accumulation of gas.

Abstract: System and method for simultaneously tracking a position of a medical device and ablating a tissue within a body. The system includes a power supply, a navigation device, and a control circuit. The power supply generates a current that is suitable for ablating tissue, such as heart tissue. The navigation device establishes a three-dimensional reference coordinate system and identifies a location of an energy delivery device in relation to the established coordinate system. The control circuit switches or alternates between activating the power supply and acquiring ultrasound data that identifies the location of the medical device within the established coordinate system.

Abstract: A dual-sectioned automotive propeller shaft features a weakened area in a first section. Under an axial load, the first section buckles transversely to a longitudinal axis of the shaft to absorb substantially all of the energy exerted against the shaft. A second section of the shaft is thereby isolated from consequences of the axial load enabling its placement and proximity to other components mounted to the undercarriage of the vehicle.

Abstract: A mask inspection method and system. Provided is a mask fabrication database describing geometrical shapes S to be printed as part of a mask pattern on a reticle to fabricate a mask through use of a mask fabrication tooling. The shapes S appear on the mask as shapes S? upon being printed. At least one of the shapes S? may be geometrically distorted relative to a corresponding at least one of the shapes S due to a lack of precision in the mask fabrication tooling. Also provided is a mask inspection database to be used for inspecting the mask after the mask has been fabricated by the mask fabrication tooling. The mask inspection database describes shapes S? approximating the shapes S?. A geometric distortion between the shapes S? and S? is less than a corresponding geometric distortion between the shapes S? and S.
