    摘要: The present invention increases the number of characters available on a stencil for charged particle beam lithography. A stencil for charged particle beam lithography is disclosed, comprising two character projection (CP) characters, wherein the blanking areas for the two CP characters overlap. A stencil is also disclosed comprising two CP characters with one or more optional characters between the two characters, wherein the optional characters can form meaningful patterns on a surface only in combination with one of the two characters. A stencil is also disclosed wherein the blanking area of a CP character extends beyond the boundary of the stencil's available character area. Methods for design of the aforementioned stencils are also disclosed.

    摘要: Methods for designing and manufacturing an integrated circuit are disclosed, in which the physical design process for a standard cell or cells utilizes a preferred diagonal direction for minimum-width patterns on at least one layer, where the standard cell or cells are used in the layout of an integrated circuit. The methods also include forming the patterns on a photomask using model-based fracturing techniques with charged particle beam simulation, and forming the patterns on a substrate such a silicon wafer using the photomask and an optical lithographic process with directional illumination which is optimized for the preferred diagonal direction.

    摘要: A transmission is provided in which gears (31 to 34) of a first gear group provided on a first auxiliary input shaft (13) to which driving force of a main input shaft (12) is transmitted via a first clutch (24) and gears (37 to 39) of a second gear group provided on a second auxiliary input shaft (14) to which the driving force of the main input shaft (12) is transmitted via an idle gear (17 to 19) and a second clutch (25) use in common gears (43 to 46) of a third gear group provided on an output shaft (16), whereby it becomes possible to cut the number of components and reduce the dimensions of the transmission. Further, since the advance/retard relationship between the timing with which the first and second clutches (24, 25) are switched over and the timing with which the synchronizing devices (35, 36, 41, 42) are switched over can be freely chosen when establishing any of the gear positions, it is possible to prevent the occurrence of shift shock due to timing lag, thus enabling gear shifting to be carried out smoothly.

    摘要: The present invention introduces methods, systems, and architectures for routing clock signals in an integrated circuit layout. The introduced clock signal clock signal structures are rendered with non Manhattan routing. In a first embodiment, the traditional recursive H clock signal structure is rendered after transforming the coordinates system such that a rotated recursive H clock signal structure is rendered. In another embodiment, a recursive Y structure is used to create a clock signal structure. The recursive Y structure may also be implemented in a rotated alignment. For clock signal redundancy, non Manhattan wiring may be used to create a clock signal mesh network.
