Filed:

Sep 6, 2007

Appl. No.:

11/851325

Inventors:

Victor Moroz - Saratoga CA, US
Dipankar Pramanik - Saratoga CA, US
Xi Wei Lin - Fremont CA, US

Assignee:

Synopsys, Inc. - Mountain View CA

International Classification:

H01L 21/336
H01L 21/8238
H01L 21/76

US Classification:

438300, 438224, 438427, 257E21548

Abstract:

Roughly described, transistor channel regions are elevated over the level of certain adjacent STI regions. Preferably the STI regions that are transversely adjacent to the diffusion regions are suppressed, as are STI regions that are longitudinally adjacent to N-channel diffusion regions. Preferably STI regions that are longitudinally adjacent to P-channel diffusions are not suppressed; preferably they have an elevation that is at least as high as that of the diffusion regions.

Synopsys, Inc. - Mountain View CA

International Classification:

G06F 17/50

US Classification:

716 55, 716122

Abstract:

A system and method are provided for laying out an integrated circuit design into a plurality of circuit layout cells having gaps therebetween, and inserting into each given one of at least a subset of the gaps, a corresponding filler cell selected from a predefined database in dependence upon a desired effect on a performance parameter of at least one circuit cell adjacent to the given gap. The circuit layout cells may be arranged in rows, and in some embodiments the selection of an appropriate filler cell for a given gap depends upon effects desired on a performance parameter of both circuit cells adjacent to the given gap. The predefined filler cells can include, for example, dummy diffusion regions, dummy poly lines, N-well boundary shifts and etch stop layer boundary shifts. In an embodiment, circuit layout cells can be moved in order to accommodate a selected filler cell.

Abstract:

Systems and methods for locating a medical device in a body lumen are provided. A first flexible elongate instrument comprises a plurality of imaging markers, and a location information sensor is disposed at the first flexible elongate instrument or at a second flexible elongate instrument configured for relative movement with respect to the first flexible elongate instrument. A processor is configured to establish a reference coordinate system based on the plurality of imaging markers, which are visible in a medical image comprising the first flexible elongate instrument disposed in a body lumen, receive diagnostic scan or therapeutic delivery information at a plurality of locations of the body lumen from the first or second flexible elongate instrument, and correlate the information with the imaging markers. A display configured to display a composite image comprising the correlated diagnostic scan or therapeutic delivery information and the imaging markers.
